EXtract 825

plastic for welding socket DN25

Extract 825 is a pneumatically operated retractable probe housing to be attached on process tanks or tubing by welding sockets DN25. 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. An intergrated PTFE scraper allows the use also in rougher processes.
