Intended Use
Ceramat® WA 160(X) Retractable Fitting
The Ceramat® WA 160 (X) pneumatic retractable fitting with ceramic sealing is used for installing
a sensor for measuring process variables in liquid media. The sensor can be cleaned, calibrated, or
replaced under process conditions (pressure and temperature).
Since the pneumatic drive unit and the process unit with the ceramic retractable fitting are sepa-
rate modules, the drive unit can be removed and replaced under process conditions.
The retractable fitting is suitable for sensors with an outer diameter of 12 mm,
· Length 225 mm, sensor head with PG 13.5
Sensors with refillable liquid electrolyte are not suitable.
The Ceramat® WA 160(X) retractable fitting allows:
• inserting and retracting the sensor under process pressure (retractable fitting)
• calibrating or adjusting the measuring system and cleaning the sensor in the running process
(different options available)
• removing or replacing the sensor after separation from the process (in SERVICE position)
Take account of the influences of humidity, ambient temperature, chemicals, and corrosion.
Safe Use
If you are not sure whether the retractable fitting can be safely used for your intended
application, please contact the manufacturer.
To ensure safe use of the equipment, you must follow the instructions given in the manual and
observe the specified temperature and pressure ranges.
The SensoGate WA 160(X) retractable fitting has been developed and manufactured in compli-
ance with the applicable European guidelines and standards. Compliance with the European
Harmonized Standards for use in hazardous locations is confirmed by the EC-Type-Examination
Certificate. Compliance with the European directives and standards is confirmed by the EC
Declaration of Conformity.
For hazardous-area applications, the sensors used must ensure proper separation of the ATEX
zones. When the retractable fitting is in
SERVICE position
, the sensor may be replaced within a
Zone 1 hazardous location.
There is no particular direct hazard caused by the operation of the device in the specified environ-
ment.
To ensure smooth performance of the measuring points with the Ceramat®, a number of impor-
tant operating and maintenance parameters must be complied with (see Ceramat WA160
Maintenance Instructions).
