Retractable probe housing EXtract 810

pneumatic

Overview
EXtract 810 is a pneumatically operated retractable probe housing designed to be attached to 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 a pneumatic position signal responds automatically. Cleaning, rinsing and calibration of the sensor is possible while the process is running.
