U-GAGEQT50U Series Sensor Analog Output

Principles of Operation

Ultrasonic sensors emit one or multiple pulses of ultrasonic energy, which travelthrough the air at the speed of sound. A portion of this energy reflects off the target

and travels back to the sensor. The sensor measures the total time required for theenergy to reach the target and return to the sensor. The distance to the object is thencalculated using the following formula:

D = ct

2

D = distance from the sensor to the targetc = speed of sound in airt = transit time for the ultrasonic pulse

To improve accuracy, an ultrasonic sensor may average the results of several pulsesbefore outputting a new value.

Temperature EffectsThe speed of sound is dependent upon the composition, pressure and temperature ofthe gas in which it is traveling. For most ultrasonic applications, the composition andpressure of the gas are relatively fixed, while the temperature may fluctuate.

In air, the speed of sound varies with temperature according to the followingapproximation:

Cm/s = 20 273 + TC

Cm/s = speed of sound in meters per secondTC = temperature in C

Or, in English units: C ft/s = 49 460 + TF

Cft/s = speed of sound in feet per secondTF= temperature in F

The speed of sound changes roughly 1% per 6 C (10 F). QT50U series ultrasonicsensors have temperature compensation available, via the 8-pin DIP switch.Temperature compensation will reduce the error due to temperature by about 90%.

NOTE: If the sensor is measuring across a temperature gradient, the compensation willbe less effective.

Analog Output Slope

The U-GAGE QT50U sensor may be programmed for either a positive or a negativeoutput slope, depending on which conditions are taught for the Min and Max Analoglimits (see Figure 1). If the Min Analog limit is the Near Window setting and the MaxAnalog limit is the Far Window setting, then the slope will be positive. If the opposite istrue, then the slope will be negative.

Sensor Programming

Two TEACH methods may be used to program the sensor: by teaching individualminimum and maximum limits, or by using the auto-window feature to center a

sensing window around the taught position. The sensor may be programmed either viaits two push buttons, or via a remote switch. Remote programming may also be usedto disable the push buttons, preventing anyone on the production floor from adjustingany of the programming settings. To access this feature, connect the gray wire of thesensor to 0 - 2V dc, with a remote programming switch connected between them.

NOTE: The impedance of the Remote Teach input is 12 k .

Programming is accomplished by following the sequence of input pulses (seeprogramming procedures starting on page 5). The duration of each pulse(corresponding to a push button click), and the period between multiple pulses, aredefined as T:

0.04 seconds < T < 0.8 seconds

Configuration

The QT50U features an 8-pin DIP switch bank for user setup. The DIP switches arelocated behind the access cover on the back of the sensor as shown in Figure 2.A spanner tool is included with each sensor for removing the cover.

DIP-Switch-Selectable Functions

Switch 1: Output Mode Select ON = 4 to 20 mA current output is enabled

OFF = 0 to 10V dc voltage output is enabled

Switch 1 configures the sensor internally to use either the current output or voltageoutput configuration.

Switch 2: Loss of Echo Mode SelectON = Min-Max ModeOFF = Hold Mode

Switch 2 determines the output response to the loss of echo. Min-Max Mode (Switch2 ON) drives the output to either the minimum value or the maximum value when theecho is lost. (Minimum or Maximum value is selected via Switch 3.)

Hold Mode (Switch 2 OFF) maintains the output at the value which was present atthe time of echo loss.

Switch 3: Min-Max DefaultON = Default to maximum output value at loss of echo (10.5V dc or 20.8 mA)OFF = Default to minimum output value at loss of echo (0V dc or 3.6 mA)

Switch 3 selects the output response to loss of echo when Min-Max Mode isselected via Switch 2. When Switch 2 is OFF, Switch 3 has no function.

Switch 4: Teach/Transmit Enable Control ON = Gray (or yellow) wire configured for remote teachOFF = Gray (or yellow) wire configured for transmit enable/disable

High (5 to 30V dc): Transmit Enabled (Power LED solid Green)Low (0 to 2V dc):Transmit Disabled (Power LED flashes at 2 Hz)

When Switch 4 is ON, the gray wire is used to teach window limits to the sensors.

When Switch 4 is OFF, the gray wire is used to enable and disable the sensors transmitburst. The sensor output will react as if a loss of echo occurred and either holdthe output or change to minimum or maximum value (depending on switch 2 and 3settings). This function may be used when multiple sensors are in close proximity,which may make them vulnerable to crosstalk interference. A PLC can be used toenable the sensors one at a time to avoid crosstalk.

Switches 5 and 6: Response Speed Adjustment

Switches 5 and 6 are used to set the speed of the output response. The four valuesfor response speed (see DIP switch settings table on page 3) relate to the number ofsensing cycles over which the output value is averaged.

Switch 7: Temperature Compensation ON = Temperature compensation enabledOFF = Temperature compensation disabled

Changes in air temperature affect the speed of sound, which in turn affects thedistance reading measured by the sensor. An increase in air temperature shifts bothsensing window limits closer to the sensor. Conversely, a decrease in air temperatureshifts both limits farther away from the sensor. This shift is approximately 3.5% ofthe limit distance for a 20 C change in temperature. With temperature compensationenabled (Switch 7 ON), the sensor will maintain the window limits to within 1.8 percentover the -20 to +70 C range.

CAUTION . . . To avoid damage to thesensor caused by staticdischarge (ESD), observe

proper ESD precautions (grounding)while adjusting the DIP switches.



5/36


The temperature sensor in the sensors bezel cannot adapt to temperature changeas quickly as an external temperature device can. When there are fast fluctuations intemperature, it may be best to use an external temperature monitor and feed its signaland the uncompensated distance measurement into a controller and perform thecompensation calculations within the controller.

Consult the factory for details on performing temperature compensation calculations.

NOTES: If temperature compensation is enabled, exposure to direct sunlight can affect the

sensors ability to accurately compensate for changes in temperature.

With temperature compensation enabled, the temperature warmup drift upon power-up is less than 0.8% of the sensing distance. After 15 minutes, the apparent distancewill be within 0.5% of the actual distance. After 30 minutes, the apparent distance wilbe within 0.3% of the actual distance.

Using the Auto-Window Feature

Teaches a sensing distance threshold centered within a fixed sensing window (a 1 m window centered on the position taught). Thisprocedure centers the analog output on the taught position at approximately 5V dc or 12 mA.

Push Button LockoutEnables or disables the keypad to prevent unauthorized personnel from adjusting the programming settings.

General Notes on Programming

1. The sensor will return to RUN mode if the limit is not registered within 120 seconds after entering TEACH Mode.

2. Press and hold the programming push button > 2 seconds (before teaching the limit) to exit PROGRAM mode without saving anychanges. The sensor will revert to the last saved program.

3. If push buttons do not respond, perform remote lockout procedure to enable push buttons.

U-GAGEQT50U Series Universal Supply Voltage

OverviewUltrasonic sensors excel in position-monitoring applications and in applications involvingclear or multi-colored targets.

QT50U sensors are available in a variety of models: dc sensors with either analog or twodiscrete outputs, or universal voltage models that feature an SPDT electromechanicalrelay for switching larger loads. Programming and setup for the universal voltage modelsare accomplished using the sensors two push buttons.

Models are available with Teflon sensor face and hex nut, plus Teflon-coated transducer and special o-rings for use in harsh environments, such as fill-level monitoring in an acid-filled tank. See models table, dimensions, and installation information on page 8 for moreinformation.

Principles of OperationUltrasonic sensors emit one or multiple pulses of ultrasonic energy, which travel throughthe air at the speed of sound. A portion of this energy reflects off the target and travels

back to the sensor. The sensor measures the total time required for the energy to reachthe target and return to the sensor. The distance to the object is then calculated usingthe following formula:

D =ct

D= distance from the sensor to the targetc = speed of sound in air t = transit time for the ultrasonic pulse


Temperature EffectsThe speed of sound is dependent upon the composition, pressure and temperature of the gas in which it is traveling. For most ultrasonic applications, the composition andpressure of the gas are relatively fixed, while the temperature may fluctuate.


In metric units:Cm/s= 0 73 + TC Or, in English units:Cft/s=49460 + TFCm/s = speed of sound in meters per secondCft/s= speed of sound in feet per secondTC = temperature in C TF= temperature in F

Temperature CompensationThe speed of sound changes roughly 1% per 6 C (10 F). QT50U series ultrasonicsensors have temperature compensation available; temperature compensation willreduce the error due to temperature by about 90%.

Changes in air temperature affect the speed of sound, which in turn affects the distancereading measured by the sensor. An increase in air temperature shifts both sensingwindow limits farther away from the sensor. Conversely, a decrease in air temperatureshifts both limits closer to the sensor. This shift is approximately 3.5% of the limitdistance for a 20 C change in temperature. With temperature compensation enabled,the sensor will maintain the window limits to within 1.8% over the entire-20 to +70 C range.

NOTES: If temperature compensation is

enabled, exposure to direct sunlightcan affect the sensors ability toaccurately compensate for changesin temperature.

If the sensor is measuring acrossa temperature gradient, thecompensation will be less effective.

With temperature compensationenabled, the temperature warmupdrift upon power-up is less than1.0% of the sensing distance. After 30 minutes, the apparent switchpointwill be within 0.5% of the actualposition. After 60 minutes, theapparent switchpoint will be within0.3% of the actual position.

Installation Chemical-Resistant ModelsThe sensor may be threaded directly into the side of a tank (seedimensions for hole diameter and thread specifications), or into a

non-threaded hole, using the included threaded nut.For a non-threaded hole, install an o-ring onto the flange, andinsert the flange completely into the hole until the sensor frontsurface is against the tanks exterior surface. Place the other o-ring into the groove on the Teflon nut, and thread the nut onto theflange (see Figure 6). Tighten enough to eliminate gaps betweenthe flange and the tank surface. This will ensure that the o-ringsare fully compressed.

U-GAGEQT50U Series Sensor Discrete Output

Principles of Operation

Ultrasonic sensors emit one or multiple pulses of ultrasonic energy, which travelthrough the air at the speed of sound. A portion of this energy reflects off the target

and travels back to the sensor. The sensor measures the total time required for theenergy to reach the target and return to the sensor. The distance to the object is thencalculated using the following formula:

D = ct

2

D = distance from the sensor to the targetc = speed of sound in airt = transit time for the ultrasonic pulse


Temperature Effects

The speed of sound is dependent upon the composition, pressure and temperature ofthe gas in which it is traveling. For most ultrasonic applications, the composition andpressure of the gas are relatively fixed, while the temperature may fluctuate.


Cm/s = 20 273 + TCCm/s = speed of sound in meters per secondTC = temperature in C

Or, in English units:

C ft/s = 49 460 + TF

Cft/s = speed of sound in feet per secondTF= temperature in F

The speed of sound changes roughly 1% per 6 C (10 F). QT50U series ultrasonicsensors have temperature compensation available, via the 8-pin DIP switch.Temperature compensation will reduce the error due to temperature by about 90%.

NOTE: If the sensor is measuring across a temperature gradient, the compensation willbe less effective.

Sensor Programming

Three TEACH methods may be used to program the sensor: Teach individual minimum and maximum limits,

Use Auto-Window feature to center a sensing window around the taught position, or Simultaneously use Auto-Window and position a threshold for background

suppression at the taught position.

The sensor may be programmed either via its two push buttons, or via a remoteswitch. Remote programming also may be used to disable the push buttons,preventing unauthorized personnel from adjusting the programming settings. Toaccess this feature, connect the gray wire of the sensor to 0 - 2V dc, with a remoteprogramming switch between the sensor and the voltage.

NOTE: The impedance of the Remote Teach input is 12 k .

Programming is accomplished by following the sequence of input pulses (seeprogramming procedures starting on page 5). The duration of each pulse

(corresponding to a push button click), and the period between multiple pulses, aredefined as T:0.04 seconds < T < 0.8 seconds

Configuration

The QT50U features an 8-pin DIP switch bank for user setup. The DIP switches arelocated behind the access cover on the back of the sensor as shown in Figure 2.A spanner tool is included with each sensor for removing the cover.

DIP-Switch-Selectable Functions

Switch 1: Output Mode Select ON = Both outputs set to PNP (current sourcing)

OFF = Both outputs set to NPN (current sinking)

This switch configures the sensor internally to use either the PNP or NPN outputconfiguration.

Switch 2: High/Low Level Control ON = High/Low (fill level control)OFF = ON/OFF (window)

This switch determines whether the sensor is in fill level control mode or normalON/OFF mode. The fill level control is shown in Figure 3. When switch 2 is ON, theswitch 3 setting will determine whether the sensor is set up for pump-in or pump-outoperation.

In ON/OFF mode, the sensor is either ON or OFF when the target is within the windowlimits and opposite when outside of the window limit.

Switch 3: ON/OFF Mode ON = normally open (output is energized when the target is within window)OFF = normally closed (output is energized when the target is outside window)

Switch 4: Teach/Transmit Enable Control ON = Gray (or yellow) wire configured for remote teachOFF = Gray (or yellow) wire configured for transmit disable

High (5 to 30V dc or open): Transmit Enabled (Power LED solid Green)Low (0 to 2V dc):Transmit Disabled (Power LED flashes at 2 Hz)

When switch 4 is ON, the gray or yellow wire is used to teach the sensors window

limits. When switch 4 is OFF, the gray or yellow wire is used to enable and disablethe sensors transmit burst. This function may be used when multiple sensors areoperating in close proximity and may be vulnerable to cross-talk interference. A PLCcan be used to enable the sensors one at a time to avoid cross-talk.

When disabled, the sensor outputs will react as if no target is being sensed.

Switches 5-6: Response Speed Adjustment The speed of the output response is set using DIP-switch positions 5 and 6 (see tableon page 3). There are four values for response speed, which relate to the number ofsensing cycles over which the output value is averaged.

Switch 7: Temperature Compensation ON = Temperature compensation is enabledOFF = Temperature compensation is disabled

Changes in air temperature affect the speed of sound, which in turn affects thedistance reading measured by the sensor. An increase in air temperature shifts bothsensing window limits closer to the sensor. Conversely, a decrease in air temperatureshifts both limits farther away from the sensor. This shift is approximately 3.5% ofthe limit distance for a 20 C change in temperature. With temperature compensationenabled (Switch 7 ON), the sensor will maintain the window limits to within 1.8% overthe -20 to +70 C range.

CAUTION . . . To avoid damage to thesensor caused by static

discharge (ESD), observeproper ESD precautions (grounding)while adjusting the DIP switches.

Power ON/OFF LED(Green) indicates the operating status of the sensor.

NOTES: If temperature compensation is enabled, exposure to direct sunlight can affect the

sensors ability to accurately compensate for changes in temperature.

With temperature compensation enabled, the temperature warmup drift upon

power-up is less than 0.8% of the sensing distance. After 15 minutes, the apparentswitchpoint will be within 0.5% of the actual position. After 30 minutes, the apparentswitchpoint will be within 0.3% of the actual position.

Output 1: Auto-Window (automatically centers a 200 mm window on taught position)Output 2: Background Suppression (sensor ignores objects beyond the taught

position)Taught position is identical for both outputs.

To adjust the Background Suppression limit (different from the limit for Output 1),teach a new limit to Output 2 using the Auto-Window procedure (page 7). Output 2will remain in Background Suppression mode until it is taught new min/max limits(page 6).

U-GAGE Chemically Resistant Ultrasonic SeTeflon -protected sensors for harsh environments

Features

Available option for all Banner QT50U and T30U..B models.

Factory-installed Teflon flange and film coating bonded over the transducer provideprotection from harsh environments.

The flange is sealed to the sensor face using a Viton o-ring; other o-ring materialsmay be specified (contact factory).

Performance specifications for these models are identical to those of correspondingstandard models, with the exception of reduced sensing range (see PerformanceCurves below).

Sensor dimensions and mounting vary somewhat from corresponding standardmodels (see dimensions on reverse).

Teflon is a registered trademark of Dupont Viton is a registered trademark of Dupont Dow Elastomers

Models

Add suffix -CRFV to the model number of any standard QT50U or T30U..B modelsensor to get this option. For example: QT50ULBQ6-CRFVor T30UINB-CRFV. Consultfactory for information on T30U..A models.

WARRANTY: Banner Engineering Corp. warrants its products to be free from defects forone year. Banner Engineering Corp. will repair or replace, free of charge, any product of itsmanufacture found to be defective at the time it is returned to the factory during the warranty

Installation

The sensor may be threaded directly intothe side of a tank (see dimensions for hole

diameter and thread specifications), or intoa non-threaded hole, using the includedthreaded nut.

For a non-threaded hole, install an o-ringonto the flange, and insert the flangecompletely into the hole until the sensorfront surface is against the tanks exteriorsurface. Place the other o-ring into thegroove on the Teflon nut, and thread thenut onto the flange (see Figure 1). Tightenenough to eliminate gaps between the flangeand the tank surface. This will ensure thatthe o-rings are fully compressed.
