Abstract
A pressure transmitter with pressure sensor mount includes pressure measurement circuitry. A metal body of the pressure transmitter has a pressure coupling configured to couple to a process pressure. A pressure sensor is configured to provide an output related to an applied pressure to the pressure measurement circuitry. A conduit is coupled to the pressure sensor and configured to apply an applied pressure corresponding to the process pressure to pressure sensor. A non-conductive spacer is configured to electrically isolate the conduit from the metal body. The non-conductive spacer has an opening formed therein and is arranged to convey the applied from the metal body to the conduit.
