Product Details

The 220-HMP155D Humidity Sensor provides reliable humidity measurement utilizing a new generation HUMICAP 180R sensor that has excellent stability and withstands well in harsh environments. The probe structure is solid and the sensor is protected with a sintered teflon filter. The 220-HMP155D is especially designed for use in meteorological applications and hydrological weather stations. It has a weatherproof IP66 housing and 11 feet of cable with an 8-pin MP12 connector. An electrical circuit in the sensor body converts the capacitance to a voltage output which is linearly proportional to the ambient relative humidity. Calibration adjustment potentiometers are provided.
