Product Description The DMP 331 compound range pressure transducer has a semiconductor strain gauge sensing element with a vent to atmospheric pressure on the reverse side of the silicon diaphragm which provides a gauge pressure reference. The Silicon element is protected from the process media by sealing it inside an oil filled capsule with a convoluted isolation membrane to facilitate the transfer of pressure to the sensing element. The DMP-331 bi-directional pressure sensor has a variety of configurations with all welded wetted parts, semi-flush diaphragm, process style electronics housing and IP68 buccaneer electrical connector.
