  • Process fluid pressure transmitter with replaceable atmospheric vent filter
    Patent number: 8863580
    Abstract: A process fluid pressure transmitter for measuring a process pressure referenced to atmospheric pressure is provided. The process fluid pressure transmitter includes a pressure sensor fluidically coupled to a pair of pressure conveying conduits. The pressure sensor has an electrical characteristic that varies with the pressures applied by the pressure conveying conduits. A process fluid inlet is disposed to contact a process fluid, and is in fluidic communication with a first conduit of the pair of pressure conveying conduits. An atmospheric vent is coupled to a second conduit of the pair of pressure conveying conduits. The atmospheric vent is replaceable and has a filter element disposed therein.
