Retractable probe housing EXtract 815M

pneumaticmanual

Product description
EXtract 815M is a manually operated retractable probe housing for welding sockets DN25, available in stainless steel (1.4404 / 316L) or Alloy C22 (2.4602). The manual rotary drive inserts the sensor into the process medium and retracts it into the cleaning chamber. A safety knob automatically locks the unit in the “measuring” and “service” positions. Cleaning, rinsing and calibration of the sensor are possible without stopping the process. An integrated PTFE scraper enables use in abrasive or rough process conditions.

Your advantages

• Integrated PTFE scraper for harsh processes
• Automatic locking with clear indication of measuring and service positions
• Automatic safety lock when sensor is removed
• Safe handling at elevated process pressures due to unique rotary drive
• Materials: stainless steel AISI 316L (1.4404) or Alloy C22 (2.4602)
• Immersion length up to 90 mm
• Suitable for ATEX areas
• Rated up to 16 bar and 140 °C
• Maintenance-free manual drive; retrofit to pneumatic drive possible

Applications

• Compatible with Ø12/225 mm and Ø12/280 mm sensors with PG13.5 thread (pH glass, ISFET, conductivity, temperature, turbidity and optical sensors)
