Mounting
• Possible mounting angle 15° above horizontal:
• Mounting angle 360° (i.e. even upside down)
for special sensors only containing thickened
electrolytes which thus cannot flow.

Function Description
SensoGate WA 132
The retractable fitting can be moved to two positions using compressed air:
• PROCESS position:
The sensor is located in the process medium.
• SERVICE position:
The sensor is located in the calibration chamber.
In SERVICE position you can clean, maintain, calibrate or adjust the measuring system.
Using compressed air, a control unit such as the Unical 9000 moves the sensor between SERVICE
position and PROCESS position and leads the different calibration or cleaning liquids to the sensor
when it is 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 or by
compressed air.
For operating the SensoGate, you must connect control air and rinsing or calibration media to the
SensoGate. There are two possible ways to do so.
• When the SensoGate is operated with a Unical or Uniclean electro-pneumatic controller and the
Protos measuring system, the cables and tubings for air pressure and rinsing/calibration media
are combined in a single hose with just one plug connection. This hose is referred to as media
connection. This media connection is installed on the SensoGate together with the outlet hose.
• When you do not use an electro-pneumatic controller (Unical or Uniclean and Protos measuring
system), you can connect the supply lines for control air and rinsing/calibration media with a
free hose connection via adapters ZU 0742 / ZU 0733 / ZU 0734 (see page 40).
To replace the sensor, you must move the retractable fitting to the SERVICE position
(see page 13) and secure it using SensoLock (see page 11).
