PRESSURE SENSOR WITH MINERAL INSULATED CABLE

摘要

A pressure measurement system (10) is provided. The system (10) includes a pressure sensing probe (16) extendable into a process fluid and having a pressure sensor (50) with an electrical characteristic that varies with process fluid pressure. A mineral insulated cable (18) has a metallic sheath (30) with a distal end attached to the pressure sensing probe and a proximal end. The mineral insulated cable (18) includes a plurality of conductors (34, 36) extending within the metallic sheath (30) and being spaced from one another by an electrically insulative dry mineral (58). The proximal end of the metallic sheath is configured to be sealingly attached to a process fluid vessel (14).
