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 using an elongate housing with a fill fluid capillary. In one example configuration, at least one thermoelectric element is included within the elongate housing to apply heat to, or conduct heat away from, the process coupling in response to an applied electric current or signal, allowing fill fluid to be preheated to facilitate cold startup or calibration, and providing cooling of the process coupling during high temperature operation.
