Retractable probe housing EXtract 830

pneumatic

Description
EXtract 830 is a pneumatically operated retractable probe housing made of stainless steel in hygienic design 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 a pneumatic position signal responds automatically. Cleaning, rinsing and calibration of the sensor is possible while the process is running.

Your advantages
