Pressure Connectors: G1/4, G1/2, 1/4 or 1/2 inch NPT male thread plus G1/2 flush diaphragm (EN837 only), open pressure port design and M20 x 1.5 male
Media Compatibility: Stainless steel 316 Ti pressure port, stainless steel 316L diaphragm with all welded, FKM or EPDM O ring internal seal
Special Features: low compound pressure ranges
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.
