OMC-408 Ex Temperature and Humidity

The OMC-408 Temperature Humidity Aensor is the Ex version of the popular OMC-406 sensor. It consists of a probe and transmitter for safe and accurate measurement of temperature and humidity in 0 and 1.

Obviously every engineer tries to keep measurement devices beyond hazardous areas; e.g. on plants, ships, LNG jetties and offshore objects. However, sometimes this is not possible. While choosing the best location for meteorological and hydrological sensors, it is sometimes required to install these in hazardous areas. Observator’s wide range of MetOcean sensors can also be supplied as Ex sensors, nowadays even supplied with required ATEX certificates.
