Diaphragm seals use a flexible barrier, (the diaphragm) to isolate a differential pressure gauge, switch or transmitter sensor from the process media. This isolation eliminates many of the adverse effects the process poses to the differential pressure gauge. Use with Mid-West models 140 & 142 diaphragm type differential pressure gauges.
A Diaphragm Seal, when properly mounted and filled, will accurately transmit process pressure to the instrument. Pressure exerted on the flexible diaphragm is transmitted hydraulically to the instrument through the fill fluid, which fills the void between the diaphragm and the instrument.
