Retractable probe housing EXtract 830M

pneumaticmanual

Product overview
EXtract 830M is a manually operated retractable probe housing in hygienic stainless steel design for mounting on process tanks and pipelines. The drive unit inserts the sensor into the process medium and returns it to the cleaning chamber. Each final position ("measuring" or "service") is automatically secured by a safety knob. Sensor cleaning, rinsing and calibration can be performed while the process remains running.

Your advantages

• Hygienic design
• Automatic locking with indicators for measurement and service positions
• Automatic safety lock when sensor is removed
• AISI 316L / 1.4404, surface finish Ra < 0.78 µm, electropolished
• Wide range of process connections and sealing materials
• Operational up to 16 bar and 140 °C
• Maintenance-free manual drive
• Easy retrofit to pneumatic drive possible

Applications

• For all 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)
• Food industry
• Pharmaceuticals
• Hygienic process applications
• Sensor replacement under process conditions
