PRESSURE TRANSMITTER WITH PRESSURE SENSOR MOUNT
First Claim
1. A pressure transmitter with pressure sensor mount, comprising:
- pressure measurement circuitry;
a metal body of the pressure transmitter having a pressure coupling configured to couple to a process pressure;
a pressure sensor configured to receive the process pressure and responsively provide a sensor output related to the process pressure to the pressure measurement circuitry the sensor output electrically coupled to the measurement circuitry;
a conduit coupled to the pressure sensor configured to apply an applied pressure corresponding to the process pressure to pressure sensor; and
a non-conductive spacer disposed between the metal body and conduit and configured to electrically isolate the conduit from the metal body of the pressure transmitter, the non-conductive spacer having an opening formed therein and arranged to convey the applied pressure from the metal body to the conduit.

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.
