The input pressure (pe) is transferred to the gauge pressure sensor ⑥ via the separating diaphragm ④ and the fill fluid ⑤, displacing its measuring diaphragm. The displacement

changes the resistance value of the four piezo resistors in the measuring diaphragm in a bridge circuit. The change in the resistance causes a bridge output voltage proportional to the

input pressure. Transmitters with measuring span ≤ 63 bar measure the input pressure against atmosphere, those with spans ≥ 160 bar against vacuum.

Differential pressure is transmitted to the silicon pressure sensor ⑤ through the separating diaphragms ⑦ and the fill fluid ⑧. When measuring limits are exceeded, the overload

diaphragm ⑥ is displaced until one of the separating diaphragms ⑦ rests on the measuring cell body ④. The separating diaphragm thus protects the silicon pressure sensor ⑤ from overload. The measuring diaphragm is displaced using differential pressure. The displacement changes the resistance value of the four piezo resistors in the measuring diaphragm in a bridge circuit. The change in the resistance causes a bridge output voltage

proportional to the differential pressure. 3.5.3.53.5.3.53.5.3.53.5.3.5 Measuring cell for absolute pressure from the differential pressure seriesMeasuring cell for absolute pressure from the differential pressure seriesMeasuring cell for absolute pressure from the differential pressure seriesMeasuring cell for absolute pressure from the differential pressure series

3.63.63.63.6 Remote sealRemote sealRemote sealRemote seal Product descriptionProduct descriptionProduct descriptionProduct description

A remote seal measuring system comprises the following elements:

• Remote seal

• Transmission line, e.g. capillary line

• Measuring device

Do not separate these components under any circumstance. The measuring system based

on a hydraulic principle is used to transfer pressure. The capillary line and the remote separating diaphragm are the most sensitive components in the remote seal measuring system. The material thickness of the remote separating diaphragm is only ~0.1 mm. The smallest of leakages in the transmission system leads to the loss of transmission fluid. The loss of transmission fluid leads to inaccuracies in the measurement and the failure of the

measuring system. In order to avoid leakages and measuring errors, please observe the following general installation and maintenance instructions in addition to the safety notes.

• Statuses ⑤ and ⑦

Depending on the customer setting, the displayed measured value ① represents the following:

• The current emitted by the transmitter

• The percentage measurement value of the adjusted measurement type, e.g. level, related to the adjusted measurement range.

• The measurement value in a selectable physical unit

The Violation of lower limit ⑤ and Violation of upper limit ⑦ displays are also referred to as status since they have meanings dependent on the settings.

If the communication display ⑧ blinks, this indicates an active communication.

In "Pressure" measuring mode, you can set or adjust the start of scale value and full scale value using the buttons. Modes 2 and 3 are used for this. Rising and falling characteristic

curves can be realized with appropriate use of the buttons. If the transmitter is not in "Pressure" measuring mode, this mode is skipped in local operation.

DifferenceDifferenceDifferenceDifference

The difference between setting and adjusting lies in the calculation.

Setting with reference pressureSetting with reference pressureSetting with reference pressureSetting with reference pressure

Condition

Two reference pressures pr1 and pr2 are available. The reference pressures are initialized by the process or generated by a pressure sensor.

When setting, a desired start of scale value or a full scale value is allocated to the standard current values (4 mA or 20 mA). After setting, the measuring span entered on the type plate may no longer correspond with the adjustment.

Depending on the series and measuring range, a maximum downscaling of 1:100 can be achieved (measuring span ratio = r, turn down).

NoteNoteNoteNote

Setting the start of scale value does not change the measuring span. Setting the full scale value does not change the start of scale value.

The start of scale value should therefore be set first, then the full scale value.

The correlation between the measured pressure and the output current generated is linear.

The square root extracting characteristic curve for differential pressure transmitters is an exception. Calculate the output current using the following formula.

Example of setting with reference pressureExample of setting with reference pressureExample of setting with reference pressureExample of setting with reference pressure A Initial situation

B Setting start of scale value C Setting full scale value

Explanations for the example of setting with reference pressure A The measuring range is from 0 to 16 bar. You are changing the start of scale value from 0 to 2 bar

and the full scale value from 16 to 14 bar. The measuring span is then 12 bar. B 2 bar process pressure is created.

Use the [M] button to set the transmitter to mode 2. To set the start of scale value, press the [↑]

and [↓] buttons simultaneously for 2 seconds. If there is 2 bar input pressure, the transmitter produces an output current of 4 mA.

C 14 bar process pressure is created. Use the [M] button to set the transmitter to mode 3. To set the full scale value, press the [↑] and [↓] buttons simultaneously for 2 seconds. If there is 14 bar input pressure, the transmitter produces an output current of 20 mA.

D The output current can be calculated for any input pressure using the "current calculation formula for setting".

NoteNoteNoteNote If the value exceeds or falls below the preset measuring limits by more than 20% when setting, the setting function is not carried out. The old value is retained in this case. With a marked elevation of the zero point, the full scale value must therefore previously be reduced such that it still lies within the permitted range after elevation of the zero point. This setting function is only possible in "Pressure" measuring mode.

Adjusting with reference pressureAdjusting with reference pressureAdjusting with reference pressureAdjusting with reference pressure Condition: The reference pressure, the adjusted start of scale value and adjusted full scale value are known. When adjusting, a start of scale value or a full scale value can be allocated to a desired current value with the aid of a reference pressure. This function is particularly suitable when the required pressures for the start of scale value and the full scale value are not available After adjustment, the measuring range specified on the type plate may no longer correspond with the setting. Using the formulae below, the current to be set for the desired start of scale value and the full scale value can be calculated. To calculate the output currents when setting the start of scale value or the full scale value, the reference pressure must be selected such that a value between 4 and 20 mA results for the current.

Explanations for the example of adjusting with reference pressure A The measuring range is from 0 to 16 bar. You are changing the start of scale value from 0 to 2 bar

and the full scale value from 16 to 14 bar. The measuring span is then 12 bar. A reference pressure of 11 bar is created.

B Use the [M] button to set the transmitter to mode 2. The "Current calculation formula for adjusting with reference pressure" can be used to calculate

the current to be adjusted for the desired start of scale value IMA (13 mA at 2 bar) with the existing reference pressure. It can be adjusted with the [↑] or [↓] buttons IMA.

C Use the [M] button to set the transmitter to mode 3. The "Current calculation formula for adjusting" can be used to calculate the current to be adjusted for the desired full scale value IME (16 mA at 14 bar) with the existing reference pressure. It can be adjusted with the [↑] or [↓] buttons IM.

NoteNoteNoteNote If the preset measuring limits are exceeded or fallen below by more than 20% during adjustment, the resulting current cannot be set above these limits. With a marked elevation of the zero point, the full scale value must therefore previously be reduced such that it still lies within the permitted range after elevation of the zero point.

7.17.17.17.1 Operating functions through HART Operating functions through HART Operating functions through HART Operating functions through HART communicationcommunicationcommunicationcommunication ConditionConditionConditionCondition

You can operate the transmitter through HART communication. The following is required for this purpose:

• A HART communicator or PC software such as SIMATIC PDM.

• A HART modem to connect a PC with the transmitter or a lead to connect a HART communicator with the transmitter.


The full functionality of the transmitter is available via HART communication. The HART communicator and PC software are not supplied with the transmitter. How to connect and

operate a HART communicator or the PC software is described in separate operating instructions or in the online help for both these tools.

Fundamental descriptionFundamental descriptionFundamental descriptionFundamental description

The input signal is provided in the form of digital information in the following variables through HART communication:

• Pressure

• Level

• Volume

• Mass

• Volume of flow

• Mass flow rate

• User programmable "characteristic curve"

As soon as you have set up the HART communication and the transmitter, you can adapt the transmitter to your relevant measuring task. When doing so you are assisted by the selectable measuring modes "Pressure", "Level", "Flow rate" and a user programmable

"Characteristic curve". One or more device variables are permanently allocated to each measuring mode in order to execute corresponding measuring tasks.

The transmitter can be set for the corresponding measuring task using a few parameters. You can select the following measuring modes:

• Pressure

• Level

• Flow rate

• Users: user programmable characteristic curve

You can use the measuring mode selector to activate measuring modes "Level", "Flow rate"

and "User".

Selecting the device variablesSelecting the device variablesSelecting the device variablesSelecting the device variables

One or more device variables are permanently allocated to each measuring mode. The following device variables are always active and are therefore always displayed:

• Pressure

• Sensor temperature

• Electronics temperature

• Pressure (untrimmed)

The following device variables are activated only when the allocated measuring mode is

activated and parameterized simultaneously:

• "Level", "Volume" and "Mass" are allocated to the "Level" measuring mode.

• "Volume of flow" and "Mass flow rate" are allocated to the "Flow rate" measuring mode.

• "User" is allocated to the "User" measuring mode.

The inactive device variables have the CONSTANT status.

7.3.27.3.27.3.27.3.2 Measuring mode selectorMeasuring mode selectorMeasuring mode selectorMeasuring mode selector

You can use this switch to toggle between measuring modes "Pressure", "Level", "Flow rate"

and a characteristic curve programmable by a "User".

If a measuring mode has been selected using the measuring mode selector, it has to be configured. This does not mean that this block has an automatic effect on the current output (4 to 20 mA). For that, you need to switch the corresponding device variable to the primary variable (PV) using a so-called variable mapper.

7.3.37.3.37.3.37.3.3 Variable mapperVariable mapperVariable mapperVariable mapper


In this transmitter, the dynamic variable that determines the behavior of current output is

always called the primary variable (PV). You need to use the variable mapper for a number of purposes, including selecting which device variable is to be switched to PV. The variable selected as PV using a PC program such as SIMATIC PDM or using the HART Communicator is scaled once again in the analog output stage to a zero value and a limit value. These two values then correspond to the current values 4 and 20 mA.

As soon as the PV is switched over using the variable mapper, the start of scale value and full scale value in the analog output stage are preset to the limit values of the new device variables. You can define these limit values within the individual block functions.

The dynamic variables "Primary", "Secondary", "Tertiary" and "Quarternary" (PV, SV, TV, QV) can be interconnected with any active device variables. Various different measuring mode examples are conceivable with a 4 bar pressure transmitter.



7.3.47.3.47.3.47.3.4 Measuring mode "Pressure"Measuring mode "Pressure"Measuring mode "Pressure"Measuring mode "Pressure"

The "Pressure" measuring mode contains the "Sensor trim" function, and is always active

since it is the standard measuring mode. When the measuring mode selector is set to "Off", further measuring variables are not derived from the "Pressure" measuring variable. Except the first four variables, all other device variables are marked as inactive and have the CONSTANT status. These four variables are mapped with dynamic variables PV, SV, TV and QV by default.

Switching an inactive device variable to the primary variable (PV) generates an error message since the variable currently does not have a valid measured value. This message is displayed in SIMATIC PDM or the HART communicator.

The volume of flow is thus 250 l/s at a process pressure of 0.5 bar. The "Mass flow rate" device variable is automatically activated when the "Flow rate" block is configured. If you have not yet configured a value for the density, the initial value of 1 kg/l is

preset. In the calculation example, a mass of 1000 kg/s is derived for the "Mass flow rate" device variable at a value of 4 kg/l. The value of density entered is used only to calculate the mass flow rate. The entered value of density has no effect on the diaphragm calculation that is to be carried out by the user. In SIMATIC PDM or the HART communicator, the "Flow rate" block is configured in an online dialog box in an extremely compact manner. In this online dialog box, you can compile all values in a menu and transfer them to the device collectively.

7.3.87.3.87.3.87.3.8 Measuring mode "User"Measuring mode "User"Measuring mode "User"Measuring mode "User"


The "User" measuring mode is the simplest of the measuring modes that you can select with the measuring mode selector. Only one further device variable, "User", is activated in this measuring mode in addition to the four standard device variables. The variables "Level", "Volume", "Mass", "Volume of flow" and "Mass flow rate" are marked as inactive and are

given the status CONSTANT.

In the "User" measuring mode, you have an option to define a customized unit for output scaling. This customized unit is, e.g. a specific quantity of liquid. This quantity of liquid depends on the input process pressure.

Example: Fill the beverages in cans having a capacity of 0.33 l. You can now define a customized unit "Can" that is exactly equal to 0.33 l. The quantity of "cans" depends on the

input process pressure.

SIMATIC PDM or the HART communicator. In the calculation example, the value at the input of the characteristic curve is transferred 1:1 to the output. In the calculation example, a number of filled cans is set for the output scaling. You can enter up to five characters for any given unit. Do not confuse this with the user-programmable

display unit of the "Analog output" block. In the calculation example, you have a start of scale value of 0 cans and a full scale value of 1000 cans. At a process pressure of 0.5 bar, you get a value of 250 cans for the "User" device variable.

If a variable having the BAD status is an output value for calculation, the measured value is BAD.

The basic measured values, namely pressure and temperatures, have the BAD status in the

following cases:

• The analog-to-digital converter does not function.

• Linearization values in the EEPROM are defective.

• If the two end points of the customized characteristic curve are exceeded for the status of the device variables of the following function.

UNCERTAIN statusUNCERTAIN statusUNCERTAIN statusUNCERTAIN status

If a pressure value exceeds or falls below the sensor limits of the device by more than 20%, the corresponding measured value and the variables inferred from it are UNCERTAIN.

If the analog-to-digital converter is overrange, the HIGH LIMIT label is allocated. If the analog-to-digital converter is underrange, the LOW LIMIT label is allocated.

Change in statusChange in statusChange in statusChange in status

If the status of a device variable changes and it was right at the front of the sequence of operations for a block, e.g. pressure, then all variables that are derived from it will take on the same status. In the following example, the device variable "Pressure" has the BAD status.

Since the measuring mode selector is set to "USER", the device variable "User" is also given the BAD status.

The reasons for changes in the status of a device variable are summarized in the table. If there were several reasons for a change in status, MANUAL always has the BAD has the second highest and UNCERTAIN the third highest priority.

The "Analog output" block converts the value provided by the dynamic primary variable (PV) into a current value of 4 to 20 mA. When you actuate the measuring mode selector, you automatically define the start of scale value and the full scale value to the current values 4 and 20 mA, respectively. Limit values of corresponding device variables are used for scaling the analog output by default. You have entered these limits when setting the parameters of

your measuring mode.

The sensor trim can be used to set the characteristic curve of the transmitter at two sensor trim points. The results are then correct measured values at the sensor trim points. The sensor trim points can be selected as any points within the nominal range.

Devices that are not turned down prior to delivery are trimmed at 0 bar and the upper limit of the nominal range; devices that are turned down prior to delivery are trimmed at the lower and upper limits of the set pressure measuring range.

Application exApplication exApplication exApplication examplesamplesamplesamples

• For a particular device that is not turned down (e.g. 63 bar), the typical measured value is 50 bar. To attain the highest possible accuracy for this value, set the upper sensor calibration at 50 bar.

• A 63-bar transmitter is turned down to 4 to 7 bar. You can attain the highest possible accuracy by selecting 4 bar for the lower sensor calibration point and 7 bar for the upper.

• A 250-mbar absolute pressure transmitter shows 25 mbar at 20 mbar (abs). A reference pressure of 100 mbar is available. You can carry out zero point correction by performing a lower sensor trim at 100 mbar. NoteNoteNoteNote

The accuracy of the test device should be at least three times as high as that of the transmitter.

The "srlin2" function has a permanently defined application point of 10%. The range up to this point contains two linear characteristic curve sections. The first section ranges from the zero point to 0.6% of the output value and 0.6% of the pressure value. The second section has a higher gradient and it goes up to the root application point at 10% of the output value and 1%

of the pressure value.

7.21.17.21.17.21.17.21.1 OverviewOverviewOverviewOverview


HART communication allows you to activate and evaluate a wide range of diagnostic functions from a central control room or onsite:

• Calibration/service timer

• Min/max indicator

• Limit monitoring modules

• Simulation of measured pressure and temperature values

• Limit monitoring of all device variables

The diagnostics strategy employed for the transmitter incorporates a diagnostic warning and

a diagnostic interrupt for diagnostic functions for monitoring limit values, e.g. for monitoring current saturation. This warning and interrupt can be configured:

• Diagnostic warning: The device transmits via HART communication the diagnostic event that has occurred. The current output value is unaffected. The message "Diagnostic Warning" alternates with the unit on the display.

• Diagnostic interrupt: The device goes into the fault current state. The message "Diagnostic Warning" or "Diagnostic Alarm" appears on the display, along with the message ERROR. In addition, the diagnostic event is made available via HART communication.

In the default settings, all warnings and alarms are switched off. You can choose to set either the diagnostic warning only or the diagnostic interrupt and warning. For HART communication, use the HART Communicator or PC software such as SIMATIC PDM. To see the steps required, refer to the attached table for operation of the HART Communicator or the help functions in the SIMATIC PDM software.

7.21.27.21.27.21.27.21.2 Operating hours counterOperating hours counterOperating hours counterOperating hours counter


An operating hours counter can be read via HART communication for the electronics and another for the sensor. For HART communication, use the HART Communicator or PC

software such as SIMATIC PDM. The counters are activated the first time the transmitter is put into operation. If the device is separated from its power supply, the counter readings are automatically stored in the non-volatile memories. That means that the current counter readings can be accessed at the next restart. The operating hours counters cannot be reset.

7.21.37.21.37.21.37.21.3 Calibration timer and service timerCalibration timer and service timerCalibration timer and service timerCalibration timer and service timer


To guarantee regular calibration of the electronics and for servicing work on the sensor, you can fit a two-stage timer to each. After the first time period has elapsed, a calibration or

service warning will be issued. After a second time period, which can be configured as a time differential, a diagnostic interrupt is reported and fault current is output.

To perform calibration work, you need to acknowledge warnings and interrupts. You can then reset the timers and switch off the monitoring function. The calibration intervals for the electronics are calculated using the following formula:

For operating/acknowledging the warnings and interrupts in SIMATIC PDM and via the HART

Communicator, the following applies:

As long as the warning/interrupt limit has not been reached, the following applies:As long as the warning/interrupt limit has not been reached, the following applies:As long as the warning/interrupt limit has not been reached, the following applies:As long as the warning/interrupt limit has not been reached, the following applies:

• "Reset" resets the timer and starts again from count 0. Monitoring remains active.

• "Acknowledge" has no effect; the timer continues running and monitoring remains active.

• "Reset and deactivate" stops the timer, resets it, and deactivates monitoring.

When the warning/interrupt limit has been reached, the following applies:When the warning/interrupt limit has been reached, the following applies:When the warning/interrupt limit has been reached, the following applies:When the warning/interrupt limit has been reached, the following applies:

• "Acknowledge" resets the warning/interrupt message, but allows the timer to keep running. In this state, a new interrupt or warning is not possible since the time limits have already been exceeded.

• "Reset" resets the warning/interrupt message and the timer. It acknowledges the interrupt or warning at the same time. The timer immediately starts running again from zero and will report again when the warning/interrupt limit is next reached. The next calibration interval is therefore immediately active.

• "Reset and deactivate W/I" resets the warning/interrupt message and the timer and deactivates it.

7.21.47.21.47.21.47.21.4 Min/max indicatorMin/max indicatorMin/max indicatorMin/max indicator


The measuring transmitter provides three min/max indicator pairs, which you can use to monitor the three measured variables Pressure, Sensor temperature, and Electronics temperature for negative and positive peak values. For each measured value, a resettable min/max indicator saves the maximum and minimum peak values in long-term storage in the

two non-volatile memories. Consequently, the values are available even after the device is restarted. The min/max indicators are also updated during a simulation.

Configuring the direction of fault currentConfiguring the direction of fault currentConfiguring the direction of fault currentConfiguring the direction of fault current The current value is proportional to pressure within the saturation limits. When the saturation limits are exceeded, the direction of fault current can however vary from the direction of saturation. The upper or the lower fault current is displayed depending on the parameter settings of the direction of fault current. You can configure the direction of fault current for a current saturation interrupt depending on your requirements. The following settings are possible under the current saturation menu: Active interrupt value The applicable settings are those under the current interrupt type menu

command. Inverse interrupt value The applicable settings are the inverse settings under the current

interrupt type menu command. Saturated interrupt value The fault current is output in the direction of current saturation. Inverse saturated interrupt value

The fault current is output in the opposite direction to current saturation.

The difference between different settings is evident in examples 3 and 4 in the following figure. Example 3 shows the direction of fault current with the "Saturated current value" setting. Example 4 shows the direction of fault current with the "Active upper interrupt value"

setting.

At t1, current reaches the configured saturation limit of 20.5 mA for the first time. At t2, the response time ends. The stop time begins and the interrupt is triggered. Time t3 is the configured end of the stop time. At t3, the interrupt is

immediately revoked even if the current then drops below the saturation limit again.

For reasons of safety, all simmeans that when the device is restarted any simulation which may be active will be shut down. You can simulate the pressure and both temperature values. It should be noted here that changing the temperatures by simulation will have no effect on the measured pressure value.

Taking the physical unit into account you can set a fixed simulation value for all three possible simulation paths. You can simulate the pressure value and both temperature values

simultaneously. While pressure simulation is activated, the transmitter willchanges in the process pressure.

The value to be simulated can be provided as a fixed value or in the form of a ramp function.Simulation of pressure and temperature values is handled in the same way in terms of parameter settings and function, so the following will only deal with the general simulation procedures "Fixed value" and "Ramp function".

For reasons of safety, all simulation data are held only in the non-volatile user memory. This means that when the device is restarted any simulation which may be active will be shut down. You can simulate the pressure and both temperature values. It should be noted here

In addition to the adjustable fixed values for all three simulation paths, you can, as a second option, also configure one ramp function in each case. Adjustable lower and upper values together determine the limits between which the simulation values with a rising or falling tendency can move. The step width can be calculated with the step number, which is also

adjustable. You can specify the rate of rise of the ramp via the duration of the individual ramp steps.

7.237.237.237.23 Limit monitorLimit monitorLimit monitorLimit monitor DescriptionDescriptionDescriptionDescription

You can activate up to three limit monitors in order to monitor any of the device variables. The limit monitor monitors a value at an upper or lower limit value. If this limit is violated it sends a diagnostic warning or a diagnostic interrupt. Select the "Limit Monitor" menu command in

SIMATIC PDM or in the HART communicator. You can program the following values for each of the three limit monitors:

Table7-4Parameter of the limit monitor

Monitoring variable You will be shown a list of the active device variables. This list is independent of the measuring mode selected.

Limit monitoring: warning / interrupt Select whether a warning or a warning plus an interrupt should be triggered when a limit is violated.

Limit monitoring: upper / lower Specify here whether a device variable monitors the upper limit, the lower limit, or both limits.

Upper limit value Upper limit value in the unit of the device variable.

Lower limit value Lower limit value in the unit of the device variable.

Hysteresis Operating point for chatter suppression in the case of small pressure changes.

Response time The time which must pass after the limit is violated before this violation is registered.

Stop time The time for which a limit interrupt or warning will always be sustained even when the event which triggered it is no longer present.

You can count the limit violations for each limit monitor by activating an event counter that provides separate, cumulative totals of upper and lower limit violations. A diagnostic warning

and / or a diagnostic interrupt can be issued once a certain numbernumber which you can also program. You can program the following values for the event counter:

NoteNoteNoteNote In order to obtain stable measured values, the transmitter must be allowed to warm up for at least 5 minutes after the power supply is switched on. The order data must match with the values given on the type plate. The transmitter is in operation as soon as the power supply is switched on. The following cases of commissioning can be taken as the typical examples. Changing the arrangements specified here may be practical depending on the system configuration.

9.39.39.39.3 Introduction to commissioningIntroduction to commissioningIntroduction to commissioningIntroduction to commissioning Following commissioning, the transmitter is immediately ready for use. To obtain stable measured values, the transmitter needs to be allowed to warm up for five minutes or so after the power supply is switched on. The measuring span which can be set corresponds to the information on the nameplate. Even in the case of a customer-specific setting configured in the factory, the zero point and the limit point will appear on the nameplate. If need be, you can change the parameters by simple user operations on the device even during commissioning.

NoticeNoticeNoticeNotice The structure of this device is modular. You can thus replace different parts with original spare parts. When replacing components, always adhere to the notes provided with the components to be replaced. This is especially applicable for devices that are used in hazardous areas.

RelatedRelatedRelatedRelated Both the individual components "Measuring cell" and "Electronics" always have a non-volatile

memory (EEPROM). Every EEPROM has a data structure that is permanently allocated to the measuring cel, or the electronics. Measuring cell data (e.g.: measuring range, measuring cell material, oil filling) are stored in the EEPROM of the measuring cell. Data of the electronics (e.g.: downscaling, electrical additional damping) is located in the EEPROM of the electronics. It is thus ensured that the data that is relevant for the remaining components is

retained when replacing the electronic unit. Before starting the replacement work, you have the following setting options via HART:

• After replacement, the common measuring range settings from the measuring cell or from the electronic unit are adopted.

• A standard parameterization is carried out.

The measuring accuracy in the specified measuring limits with a 1:1 downscaling can be reduced by the temperature error in unfavorable cases.

In the course of further technical development, it is possible to implement advanced functions

in the measuring cell or the electronic unit. This is indicated by modified Firmware statuses (FW). The Firmware status does not have an effect on the replaceability. The scope of functions however is limited to the functioning of the older components.

If a combination of certain Firmware statuses of measuring cell and electronic unit is not possible due to technical reasons, the device identifies this status and goes into the "Fault

current" status. This information is provided via the HART interface.

10.410.410.410.4 Notes for servicing of the remote sealNotes for servicing of the remote sealNotes for servicing of the remote sealNotes for servicing of the remote seal

The remote seal measuring system usually does not need servicing. If the mediums are contaminated, viscous or crystallized, it could be necessary to clean the diaphragm from time to time. Use only a soft brush and a suitable solvent to remove the

deposits from the diaphragm. Do not use corrosive cleaning agents. Prevent the diaphragm from getting damaged due to sharp-edged tools.

The AccuFlo P, DS III series is approved by "EHEDG". The AccuFlo P300 is approved by "EHEDG" and "3A" for example.

The same flanges and flush mounted connections are used for both the pressure

transmitters. The connections for both the abovementioned approvals are thus specified.

Since the AccuFlo P, DS III series transmitter is not approved by "3A", the connections marked with "3A" are not applicable for the AccuFlo P, DS III series.

FIT Failure in Time Frequency of failure Number of faults withing 109 hours

HFT Hardware Fault Tolerance Hardware fault tolerance: Capability of a function unit to continue executing a required function in the presence of faults or deviations.

MooN "M out of N" voting Classification and description of the safety-instrumented system in terms of redundancy and the selection procedures used. A safety-instrumented system or part that consists of "N" independent channels. The channels are connected to each other in such a way that "M" channels are in each case sufficient for the device to perform the safety instrumented function. Example: Pressure measurement: 1oo2 architecture. A safety-instrumented system decides that a specified pressure limit has been exceeded if one out of two pressure sensors reaches this limit. In a 1oo1 architecture, there is only one pressure sensor.

MTTR Mean Time To Restoration Average period between the occurrence of a fault in a device or system and restoration of functionality

PFD Probability of Failure on Demand Probability of dangerous failures of a safety function on demand

PFDAVG Average Probability of Failure on Demand

Average probability of dangerous failures of a safety function on demand

SFF Safe Failure Fraction Proportion of safe failures: Proportion of failures without the potential to bring the safety-instrumented system into a dangerous or non-permissible functional status.

SIL Safety Integrity Level The international standard IEC 61508 defines four discrete Safety Integrity Levels (SIL 1 to SIL 4). Each level corresponds to a range of probability for failure of a safety function. The higher the Safety Integrity Level of the safety-instrumented system, the lower the probability that it will not execute the required safety functions.

SIS Safety Instrumented System A safety-instrumented system (SIS) executes the safety functions that are required to achieve or maintain a safe status in a system. It consists of a sensor, logic unit/control system and final controlling element.
