pneumatic retractable housing made of plastic
Extract 820 is a pneumatically operated retractable probe housing to be attached on process tanks or tubing. The drive unit inserts the sensor into the process medium and back into the cleaning chamber. When reaching the final position of the “measuring” or “service” position, the probe housing responds automatically with a pneumatic position signal. Cleaning, rinsing and calibration of the sensor is possible while the process is running.
