Page 8: Function Description
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. -
Page 9: Overview Of Retractable Fitting
Overview of Retractable Fitting SensoGate WA 132 The SensoGate retractable fitting has a modular design. This allows the drive unit, immersion tube and process adaptation to be exchanged. The retractable fitting consists of two main units: The drive unit performs the required movements to move the sensor into and out of the process. The process adaptation comprises the process-wetted part of the calibration chamber. -

Page 11: Sensolock
SensoLock SensoGate WA 132 The SensoLock ring securely blocks the retractable fitting in SERVICE position. Twisting the SensoLock ring to the “lock“ position mechanically locks the internal lift piston and thus prevents the retractable fitting from moving to PROCESS position. The SensoLock ring can only be rotated when in SERVICE position. -

Page 23: Sensors With Liquid Electrolyte
Sensors with Liquid Electrolyte SensoGate WA 132 You can use sensors with a length of 250 mm and an electrode diameter of 12 mm, e.g., Knick SE 551. To ensure that the electrolyte flows from the reference electrode to the process medium, the air pressure in the sensor pressure chamber must be 0.5 to 1 bar above that of the process medium. -
Page 24: Removing The Sensor
Sensors with Liquid Electrolyte SensoGate WA 132 Removing the Sensor 1) Before removing the sensor, make sure that the retractable fitting is in SERVICE position and secured with SensoLock (the rubber bellows is expanded). 2) Remove the cable jack. 3) Before removing the sensor, check that there is no liquid leaking from the outlet (process sealing might be defective). -
