Seals provide a protective barrier between a pressure sensor such as a gauge, switch, transmitter or transducer and the process media. Chemical seals protect pressure instruments against corrosion, abrasion, viscosity and crystallizing media. Diaphragm seal housings are available in stainless steel, carbon steel, Hastelloy, PTFE and titanium materials. Diaphragm materials include 316 stainless steel, PTFE, Viton, Monel and tantalum metals. Configurations include threaded, flanged, in-line flow-through, sanitary and remote capillary systems.
