Retractable probe housing EXtract 815

pneumatic

Product description
EXtract 815 is a pneumatically operated retractable probe housing for mounting on process tanks or piping via DN25 welding sockets (G1 1/4"). The drive unit inserts the sensor into the process medium and retracts it into a cleaning chamber. Pneumatic position signals indicate the measuring and service positions. Sensor cleaning, rinsing and calibration are possible in-line while the process runs. An integrated PTFE scraper permits use in abrasive or rough processes.

Your advantages

• Integrated PTFE scraper and robust industrial design
• Extends sensor lifetime and reduces maintenance efforts
• Automatic safety lock when the sensor is removed
• Plug-and-play installation with colour- and size-coded connections
• Integrated limit switches (pneumatic / electrical)
• Suitable for use in ATEX areas
• Immersion length up to 90 mm
• Rated up to 16 bar and 140 °C
• Wetted materials: stainless steel AISI 316L / 1.4404 or Alloy C22
• Can be fully automated with electropneumatic control unit EXmatic 470
• Maintenance-free drive unit

Applications

• For Ø12–225 mm sensors or Ø12–280 mm liquid-filled sensors with PG13.5 thread (pH glass and ISFET sensors, conductivity, temperature, turbidity and other optical sensors)
• Chemicals
• Water and wastewater treatment
• Abrasive or rough processes
• Processes requiring automated sensor cleaning or calibration
