The air temperature and humidity probe OMC-406 provides accurate and precise measurements of both temperature and humidity in two 4Š20mA outputs. The temperature sensor within the probe is a Pt 100 element, while the principle of humidity measurement is based on a capacitive measuring device.
The OMC-406 should be mounted on a OMC-422 Natural Aspired Anti-Radiation Shield, which is a naturally ventilated, multi-plated 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.
