Differential pressure transmitter with pressure sensor protection

摘要: A differential pressure to electrical signal transmitter has a pair of barrier diaphragms and one or two central control located between the diaphragms. chamber on outside diaphragm is pressurized with first fluid, other second fluid. First chambers diaphragm, length capillary tubing connected remotely sensor capsule, are filled incompressible fill liquid. Second another The pressures liquids act opposite sides minute displacement sensing element, chambers, displace element cause it produce an output which dependent upon difference liquid pressures, hence fluids.
