Your Expert Diaphragm Seal Supplier in China

BCST diaphragm seal could be a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the fabric being contained. Common uses for diaphragm seals are to shield pressure sensors from the fluid whose pressure is being measured.

BCST diaphragm seal is employed with pressure gage, pressure transmitter, pressure switch, and pressure transducers on process applications. In addition, BCST manufactures an entire line of diaphragm seals for a range of industries and processes.
