Properties, Features, Operating ParametersCeramat® WA 150(X) Sensor Lock-Gate with Ceramic Sealing

Chemically aggressive and solid-containing process media corrode the seals of conventional retractable fittings and shorten the service life of the sensor technology. In addition to chemi-cal stresses, this causes common elastomeric gaskets to become dynamically deformed on every insertion and retraction from the process. Any fibers or particles present additionally stress the elastomeric gaskets mechanically or abrasively. This considerably shortens the service lives of these lock-gates. Replacing the components is then typically a long and complicated procedure. The process must be interrupted, making expensive downtimes inevitable.

Properties and featuresWith the Ceramat®, Knick offers a ceramic sensor lock-gate which does not require conventional O-ring seals. With the pneumatically operated retractable fitting for automatic maintenance and calibration of the sensors, the rotary movement of two highly planar, hard ceramic disks ensure the safe sealing of the calibration chamber from the process. Thanks to the robust ceramic slide and a fixed outer housing made of carbon fiber-reinforced PEEK or PVDF, the lock-gate is suitable for use in highly corrosive, abrasive and fibrous media which form heavy deposits. The elasto-meric gaskets used for inflow and outflow are statically loaded and subject to no rolling stress. An elastomeric gasket on the sensor socket is moved axially against a honed and flushed surface and is not subject to rolling stress. All relevant elastomeric gaskets can be checked under process pressure when the ceramic process gate is closed (without interrupting the process) and replaced if required. This considerably increases measuring point availability – many difficult measuring points are only possible at all with this technology. If sensors are defective or broken, they can be exchanged without interrupting the process. In the event of broken glass, the pneumatic drive can be disconnected from the process unit under process pressure when the ceramic process gate is closed. The closed ceramic process gate can then be rinsed and any glass splinters removed. If required, damaged O-rings on the disconnected pneumatic drive can be replaced.

Operating and maintenance parametersTo ensure smooth performance of the measuring points with the Ceramat®, a number of impor-tant operating and maintenance parameters must be complied with. It is, for example, strongly recommended that cavity rinsing is activated to flush away process medium which has permeated the cavity (diffusion) between the outer housing and the ceramic (see “Cavity Rinsing“ on page 9).The operating and maintenance information below describes the few maintenance procedures required to ensure smooth operation of the retractable fitting, even under the most difficult measuring point conditions.

Checking the Sensor Installation / Sensor Dismount GuardOnly relevant with Ceramat® for sensors with solid electrolyte

In conjunction with the Unical® or Uniclean® electro-pneumatic controllers and the Protos® measuring system, the Ceramat® is fitted with a sensor dismount guard. This serves to prevent the immersion of the sensor lock-gate without sensor (a message is triggered in the Protos®). If the sensor is absent or incorrectly mounted, compressed air noticeably and audibly escapes from a leak, whose position can therefore be determined, below the drive’s coupling nut (see fig.).The compressed air escaping from this leak is detected by a flow switch in Unical® and signals the missing or incorrectly mounted sensor in Protos®. Note: All information regarding the sensor dis-mount guard in the Unical® is equally applicable to Uniclean®.

The sensor dismount guard only works with a correctly installed O-ring and slip ring on the sensor (see fig.). If these elements are not pres-ent, the “sensor dismounted” message is shown in the Protos® display.Before installing a new sensor, check whether there are any sealing elements at the bottom of the sensor holder from previous installations which have not been removed!

Checking the Sensor Dismount Guard Only relevant for operation with Unical-Protos

While applying compressed air, loosen the mounted sensor from the thread of the sensor holder. If the sensor dismount guard is intact, compressed air audibly escapes and the following mes-sage is shown on the Protos®: “Sensor dismounted”. On tightening the sensor in the thread, the message disappears and no more compressed air escapes.

Possible Errors

Error Actions

Sensor is installed. Very small amounts of air are escaping. No trigger of the flow switch in Unical® and therefore no “Sensor dismount-ed” message in Protos®.

No action required.This minor leakage does not impair the function of the Ceramat®!

Sensor is installed. Air is nevertheless audi-bly escaping and releases the flow switch.“Sensor dismounted” message in Protos®.Sensor cannot be inserted into the process via Unical®.

Check correct installation of the sensor. Check sensor gaskets. Where applicable, switch off safety function of the sensor dismount guard in Unical® (see Unical® 9000 user manual) to continue operating the measuring point without the safety function.To repair the safety function, send in the fitting to the factory.

Sensor is dismounted. No exhaust air is escaping. No trigger of the flow switch in Unical® and therefore no “Sensor dismount-ed” message in Protos®. The safety function is therefore suspended.Caution! It is possible to insert the fitting into the process without an installed sensor

Continued operation of the Ceramat® is possible without the safety function.To repair the safety function, send in the fitting to the factory.

Despite clearly noticeable and audible exhaust air, no trigger of the flow switch in Unical® and therefore no “Sensor dismounted” message in Protos®.

Flow switch defective.Replace flow switch.

No noticeable or audible exhaust air. The flow switch is nevertheless constantly released.“Sensor dismounted” message in Protos®. Sensor cannot be inserted into the process via Unical®.

Visual Check of Drive FunctionCeramat® WA 150(X) Sensor Lock-Gate

Visually check the movement of the drive unit. To do so, move the drive unit from the PROCESS to SERVICE position and back several times.Use the manual control of the Unical® and the Protos® or the ZU 0631 standard-media interface (see page 20).Make sure that the stroke movement is complet-ed (see fig. state B) before the rotary movement towards SERVICE position starts (see fig. state C).

The rotary position indicator must not move during the stroke movement.

Cavity Rinsing Function and function check

FunctionIn SERVICE position, inlet and outlet are directly connected with the calibration chamber. The ceramic slides are mounted in an outer housing made of plastic, which is in contact with the pro-cess. Due to diffusion (permeation), process fluids may penetrate into the cavity between ceramic and outer housing. Such fluids can be drained off using the cavity rinsing function. For this pro-cedure, the inlet is rerouted to the cavities when the WA150 moves to PROCESS position. When the rinsing function is activated (e.g. by Unical®), the cavities are rinsed and the fluids are drained off through the outlet. Normally, rinsing should be performed every 8 hours for 30 seconds. With very frequent probe movements, aggressive, sticky or fibrous process media, the rinsing intervals should be accordingly reduced.

Function check Move WA150 to PROCESS position, activate rinse water for 30 sec. using Unical® manual control. Collect rinse water at outlet hose and measure the volume. Flow should be between 0.5 and 1.5 l/min. If the flow is too low or missing, the channels in the ceramic slides are probably clogged (e.g. by lime or process residues). A possible remedy is cleaning with dilute acid. Residues and deposits can also be removed after installation with the help of the Unical® controller and the cleaner pump. For this, move the Ceramat® into PROCESS position. Using the Unical® manual control, release 1 to 2 pump strokes of cleaner and allow to act for a few minutes. Then rinse with rinse water. If necessary, repeat and watch the outlet to see if sufficient rinse water is discharged. Finally, detach the Ceramat® drive unit and check the ceramic process gate for deposits.

Disconnecting the Drive Unit from the Process Unit Ceramat® WA 150(X) Sensor Lock-Gate

Move the drive unit to the SERVICE position.Remove sensor. The ZU 0647 sensor mounting wrench (19 mm) is recommended for this.Loosen the coupling nut. Use the ZU 0648 Ceramat mounting wrench for this(see page 21).

Caution! Before disconnecting the drive unit under process pressure, observe the outlet hose. If process medium is discharged from the outlet hose, the lock-gate function is defective. When loosening the coupling nut, make sure that no process medium is leaking from the outlet. In this case, always switch the system to unpres-surized before disconnecting the drive unit to avoid discharge of process medium. Have defec-tive sensor lock-gates repaired at the factory.

The drive unit can only be disconnected from the process unit if the Ceramat® is moved to the SERVICE position. Only then is the ceramic pro-cess gate closed and the drive unit mechanically unlocked from the process unit (safety function).Caution! Attempts to remove the drive unit when not in the SERVICE position wlll result in serious damage to the fitting and represents a safety risk (open ceramic process gate)!

While loosening the coupling nut, pull the drive unit upwards until it becomes completely free.Then fully disconnect the drive unit from the process unit.

Checking / Replacing the O-Rings of the Drive UnitCeramat® WA 150(X) Sensor Lock-Gate

Removing the sensor socket:After removing the drive unit, the sensor socket is hard to access in the SERVICE position. It is therefore advisable to return the drive unit to the PROCESS position after removal. When con-trolling via Unical® and Protos®, you should use manual control with Unical® (see Unical®, Protos® user manuals).

Installing the Drive Unit in the Process UnitCeramat® WA 150(X) Sensor Lock-Gate

Note! Before installing the drive unit in the process unit, check whether the drive unit is in SERVICE position. Only then can the drive unit be inserted sufficiently deep into the process unit so that the thread of the coupling nut can engage.When mounting the drive unit to the process unit, make sure that the guiding grooves of the drive unit engage with the guiding bars of the process unit (see double groove in fig.). After successful alignment, the drive unit can be inserted and the coupling nut screwed until it noticeably stops. Where required, continue to press the drive unit in while screwing the coupling nut to make screwing easier. Hand tighten the coupling nut with the ZU 0648 Ceramat mounting wrench (refer to “Accessories“ on page 21).Now, the sensor can be installed. Use the ZU 0647 Ceramat mounting wrench (19 mm) for this (refer to “Accessories“ on page 21).

Turn the drive unit so that the double bars engage with the double groove!

Maintenance IntervalsCeramat® WA 150(X) Sensor Lock-Gate

Because of the highly variable process conditions (pressure, temperature, chemically aggressive media etc.), general information on necessary maintenance intervals is difficult to provide. If proven experience has been gained from similar points of measurement with regard to materi-als used and their resistance unter process conditions, the maintenance intervals can be adjusted by the customer. If previous experience is positive, parts of the first inspection may be omitted.

The following maintenance intervals are generally recommended by the manufacturer:

Maintenance interval* Operations required

First inspection after a few weeks Move the probe to the PROCESS position and observe the outlet. If the sensor lock-gate is untight, process fluid will leak from the outlet hose. Move the probe to the SERVICE position. Remove the drive unit (no process interrup-tion necessary) and carry out visual checks of the O-rings to check the general suitability of the material used under the present process conditions (refer to “Disconnecting the Drive Unit from the Process Unit“ on page 10 and “Checking / Replacing the O-Rings of the Drive Unit“ on page 11).

After 1-2 years or 30,000 strokes(after successful first inspection and suitabili-ty of all materials used, this time period may be extended.)

Check/replace the dynamically loaded O-ring on the sensor socket, check the statically load-ed O-rings without process interruption (see also “Checking / Replacing the O-Rings of the Drive Unit“ on page 11).Where required, examine the cavity rinsing (see “Cavity Rinsing“ on page 9).If deposits or chemical attacks on the probe housing are suspected (visible in the probe housing after removing the drive unit), check the process unit (see “Checking the Process Unit“ on page 14).

After 10 years or 500,000 strokes Complete maintenance at the factory with replacement of pneumatic sealings, lubricants, and check of all functions, pressure test, leak test

* The intervals are rough recommendations and vary with the individual application.
