Microwave humidity sensor with probe and stainless steel housing MWM 200 PCE Instruments

Product description:

• Moisture sensor, with continuous measurement in oil, diesel, fuel, sand and grit.
• It consists of a central probe surrounded by four probes.
  • The distance between the central probe and the surrounding probes is 25 mm.
• The device is made of AISI 321 stainless steel, offering high resistance against corrosion.
• The diameter of the bolt is 12 mm.
• The upper part of the sensor integrates an internal thread into the tube.
  • It functions as a coupling for mounting on a pipe with a diameter of 33 mm.
• The cable, which connects the sensor to an electronic unit, is hermetically sealed in the pipe.
• It can be operated at temperatures up to +145 °C.
