Chemical / Diaphragm Seal Unit
Corrosive process fluid.Process fluid having sediments or is viscous.Process fluid has a tendency to solidify, freeze or crystallise at lower
temperatures which may block the sensing element.Process fluid is hazardous.The diaphragm seal transmits process pressure to the instrument
through a diaphragm. The instrument side of the diaphragm is filledwith appropriate fluid. As liquids are incompressible, pressure ishydraulically transmitted to the pressure sensing element.Proper selection of diaphragm seal is important after reviewing
