Thermoelectric heating, cooling and power generation for direct mount and dual compartment fill remote seal systems

A pressure transmitter assembly for measuring a process pressure of an industrial process, comprising:

• a pressure sensor configured to sense the process pressure;
• and
• a process coupling configured to couple the pressure sensor to the industrial process, the process coupling comprising:
• an elongate housing having a process mount configured to couple to process fluid of the industrial process and an opposed coupling configured to couple to the pressure sensor;
• a capillary in the elongate housing extending from a process end adjacent the process mount to a pressure end adjacent the opposed coupling, the capillary having a fill fluid contained therein which conveys the process pressure at the process mount to the opposed coupling;
• at least one thermoelectric element configured to apply heat to, or conduct heat away from, the process coupling in response to an applied electric signal.
