Abstract: A pressure transmitter assembly for measuring a process pressure of an industrial process includes a pressure sensor configured to sense the process pressure. A process coupling couples the pressure sensor to the industrial process. In one example configuration, a phase change material carried in the process coupling is configured to reduce heat transfer from the industrial process to the process variable sensor by changing phase in response to heat from the industrial process. In another example configuration, a thermocouple electric cooling element is coupled to the process coupling and configured to conduct heat away from the coupling in response to an applied electric current.
