Retractable probe housing EXtract 821

pneumatic

Extract 821 is a retractable holder made of plastics to be attached on process tanks or tubing with an extended immersion length up to 207mm. The drive unit inserts the sensor into the process medium and back into the cleaning chamber. When reaching the final position of “measuring” or “service”, the armature responds automatically by a pneumatic position signal. Cleaning, rinsing and calibration of the sensor is possible while the process is running.
