OIL HUMIDITY SENSOR

  • Continual condition monitoring of oils
  • Two analog outputs for relative moisture and temperature
  • High pressure resistance
  • Quick installation via process connection
For 8-wire cordsets the core colors are not standardized. Please note the wiring of the sensor and the cordsets (see data sheet).
