Temperature and Humidity Sensor

Temperature and Humidity Sensor


Observator's Air Temperature and Humidity Sensor OMC-406 provides accurate and precise measurements of both temperature and humidity in two 4…20 mA outputs. The temperature sensor within this probe is a Pt100 element while the principle of humidity measurement is based on a capacitive measuring device.

The OMC-422 Natural Aspired Anti-Radiation Shield is a naturally ventilated, multiplated shield, designed for ambient temperature and relative humidity sensors. The convenient size and weight of this type make it useful for a wide range of applications and it is recommended for all new installations.
