Diaphragm seal with flanged connection FP 340
Fantinelli
Diaphragm seal consists of an elastic element that insulates the process fluid from the sensing element, transmitting pressure through the compression of a liquid in a separation chamber. It is necessary to adapt this device where there are particular physical and chemical characteristics incompatible with the sensing element. This way the instrument is no more subject to drawbacks caused by particularly aggressive fluids or by highly viscous, crystallizable or solidifiable process fluid. The diaphragm seal is an integral part of the instrument, so there is no possibility of disassembling. Diaphragm seals shown below are suitable born for SP 300 and SP 2000 series (Bourdon tube pressure gauges), for DP series (differential pressure gauges), for TR series (pressure gauges with integrated trasmitter) and SE series (transmitters or pressure switches).
