Abstract: A remote seal assembly for a process transmitter includes a seal body containing a cavity sealed by a diaphragm. The seal body configured to be mounted to a process element containing a process fluid such that a first side of the diaphragm is exposed to the process fluid. A capillary contains a fill fluid that is in fluid communication with the cavity and a second side of the diaphragm. A coupling has a capillary recess and two cavities separated by a second diaphragm. The capillary extends through the capillary recess and connects to the coupling such that the fill fluid in the capillary is in fluid communication with one of the two cavities and the second diaphragm. A thermally conductive element preferably extends continuously along the capillary from the seal body toward the coupling and into the capillary recess without contacting the coupling.

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.
