FILL FLUID THERMAL MANAGEMENT

摘要

A remote seal assembly (100) for a process transmitter (128) includes a seal body (102) containing a cavity (110) sealed by a diaphragm (106). The seal body (102) configured to be mounted to a process element (104) containing a process fluid such that a first side of the diaphragm (106) is exposed to the process fluid. A capillary (112) contains a fill fluid that is in fluid communication with the cavity (110) and a second side of the diaphragm. A coupling (116) has a capillary recess and two cavities (120,122) separated by a second diaphragm (118). The capillary (112) extends through the capillary recess and connects to the coupling (116) such that the fill fluid in the capillary (112) is in fluid communication with one of the two cavities (120, 122) and the second diaphragm (118). A thermally conductive element (402) preferably extends continuously along the capillary from the seal body toward the coupling (116) and into the capillary recess without contacting the coupling (116).
