Function Description
SensoGate WA 133
The pneumatically operated retractable fitting can be moved to two positions:
•
PROCESS position:
The sensor is located in the process medium.
•
SERVICE position:
The sensor is located in the calibration chamber.
To replace the sensor, you must move the retractable fitting to the SERVICE position (see “SERVICE
Position” chapter). The same applies when shutting down the retractable fitting.
In SERVICE position the measuring system can be calibrated or adjusted or the sensor can be
cleaned. Through the rinse connection, different calibration or cleaning liquids can be transferred
to the sensor located in the calibration chamber. These liquids leave the calibration chamber
through an outlet hose, i.e., they are displaced from the calibration chamber by following liquids.
Control Air and Feedback
The pneumatic retractable fitting is controlled by introducing compressed air. The compressed-air
hoses have an outer hose diameter of Ø 6 mm and are connected to push-in fittings.
The icons indicate the travel direction of the retractable fitting:
•
P:
Move the retractable fitting to the PROCESS position (measuring position).
•
S:
Move the retractable fitting to the SERVICE position (rinsing, calibration, and
service position).
