225-HMP155 and 225-HMP60 RH/Temp Sensors
225-HMP155 & 225-HMP60 RH/Temp Sensors

The 225-HMP60A Relative Humidity & Temperature Sensor features the laser trimmed INTERCAP® capacitive for accurate relative humidity measurements. The chip is user replaceable and requires no calibration. A membrane filter protects the sensor from dirt and dust. The 225-HMP60A also measures temperature. The sensor should be mounted in a solar radiation shield when placed outdoors.

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.

The 225-500-B Relative Humidity & Temperature Sensor has the addition of an integrated circuit transducer that provides a linear microamp current output proportional to temperature. The 225-501-B utilizes a one-element thermistor and the 225-HMP155A uses an active temperature circuit with a linear 0-1 Vdc output. Contact NovaLynx for other temperature sensor options.
