Retractable probe housing EXtract 825

pneumatic

Extract 825 is a retractable holder 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. Your advantages • Robust design, integrated PTFE scraper • Usable for DN25 welding socket • Extension of sensor-lifetime and reducing of maintenance efforts • Automatic safety lock while sensor is removed • Usable in ATEX-areas • Immersion length 70mm • Up to 10 bar and 140 °C • PP / PVDF or PEEK • Can be fully automated with electropneumatic control unit EXmatic 470 • Drive unit free of maintenance Specifications • Process pressure0…10 bar • Process temperature-10…140°C • Ambient temperature-10…70°C • Immersion length70mm • O-ring position25mm • SensorsØ12-225mm PG 13.5 • MaterialsPP, PVDF, PEEK • SealingsEPDM, FPM (Viton), FFKM (Kalrez) • Process connectionG1 1/4" (DN25) • Cleaning portsG1/8", G1/4", FNPT 1/4" • Operating power: compressed air 4...6 bar • Limit switchespneumatic, integrated
