ABSTRACT:
An isolation assembly for connection to a process transmitter and for mitigating high temperature effects of a process fluid includes a process coupling face having an isolation diaphragm configured to contact process fluid. A transmitter coupling has a pressure coupling configured to couple to a pressure port of the process transmitter. A temperature isolation fluid conduit extends between the process coupling face and the transmitter coupling and carries an isolation fluid which couples a pressure applied to the isolation diaphragm to the pressure coupling to minimize high temperature effects of the process fluid on the process transmitter.
