Retractable probe housing EXtract 815

pneumatic

Extract 815 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 rough processes. Your advantages • Robust design, integrated PTFE scraper • Extension of sensor-lifetime and reducing of maintenance efforts • Automatic safety lock while sensor is removed • Plug and play installation, colour- and size-coded connection system • Integrated limit switches • Usable in ATEX-areas • Immersion length up to 90mm • Up to 16 bar and 140 °C • Stainless steel AISI 316L / 1.4404 or Alloy C22 • Can be fully automated with electropneumatic control unit EXmatic 470 • Drive unit free of maintenance Specifications • Process pressure: 0…16bar • Process temperature: -10…140°C • Ambient temperature: -10…70°C • Immersion length: up to 90mm • O-ring position: 28mm / 50mm • Sensors: Ø12-225mm PG 13.5 • Materials: stainless steel 1.4404 /316L, Alloy C22 (2.4602) • Sealings: EPDM, FPM (Viton), FFKM (Kalrez) • Process connection: G1 1/4" (DN25) • Cleaning ports: G1/8", G1/4", FNPT 1/4" • Operating power: compressed air 4...6 bar • Limit switches: pneumatic, integrated
