OMC-406 Temperature & Humidity Sensor
2Pages

The Temperature humidity range consists of several sen- sors and accessories, for measuring air temperature, sea water temperature and relative humidity. As standard an OMC-406 is used for measurement of temperature and humidity. This sensor is supplied with two 4..20 mA out- puts and should be mounted into a radiation shield. When only air temperature is required the OMC-443 may be ap- plied. This sensor is also used on board ships for sea wa- ter temperature. In this last case the sensor is mounted into a the sea water inlet using a thermo well.

The air temperature and humidity probe 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 princi- ple of humidity measurement is based on a capacitive measuring device. The air temperature sensor OMC-443/448 provides an ac- curate measurement of temperature using a Pt100 sensing element. A build-in amplifier is provided with a 4...20 mA output. This corresponds with -40 to +60 deg. C. Of course other ranges are available on request. nection and fits in the OMC-449...
