Maintenance Work on the Drive Unit 

SensoGate® WA 131 H

The drive unit must be removed, for example:

•  for general maintenance or inspection

•  to clean the calibration chamber, e.g. after a sensor has broken

•  to change the sensor / calibration-chamber gaskets

•  in the event of a technical fault of the drive unit.

WARNING!

To separate the sensor lock-gate safely from the process, make sure  

that it is disconnected from all process media and process pressure.

CAUTION!

Before working on the drive unit, make sure that the sensor lock-gate is in 

SERVICE position (see “Function Description” on page 10).
