Hazardous Area Dew Point Transmitters

Hazardous Area Dew Point Transmitters, Analyzer in explosion proof enclosure, UL approved for use in Hazardous Locations Class I Division 1 Group B, C & The Analyzer uses an Aluminum Oxide sensor. The breakhrough technology represents advances in thin film and metal oxide sciences and offers significant performance advantages over all other aluminum oxide sensors.The operating principle of the aluminum oxide sensors is that a hygroscopic layer of aluminum oxide adsorbs or releases water molecules within its pores, depending on the water vapor pressure in its environment. The electrical capacitance of the aluminum oxide layer changes with the surrounding water vapor pressure. The electrical capacitance is measured between the aluminum core of the sensor and a porous conductive gold layer on the outside. This results in a very sensitive sensor with fast response.
