5.3 Installing and Removing Sensors
5.3.1 Safety Instructions on Installing and Removing Sensors
WARNING! Process medium, possibly containing hazardous substances, can escape from the
SensoGate WA131M.
Follow the safety instructions.
CAUTION! Risk of cutting injuries from broken sensor glass.
Handle the sensor with care. Follow
the safety instructions in the related sensor documentation.
Note:
The outlet is used to drain trapped process medium and must not be closed. By moving the sen-
sor to the respective limit positions, pressurized process medium can enter the calibration chamber
and be compressed when the outlet is closed. This process medium may splash out during sensor re-
placement.
