Abstract
A process seal assembly adapted for installation to a process vessel opening. A probe with a probe connector connects to a rod inside a passageway of a housing adapted to be sealingly mounted to the process vessel opening. The rod has a first end coupled to the probe connector and a second end adapted to couple with a transmitter connector body. A rigid, electrically insulating spool is fastened in the passageway, with an outer spool surface fitting tightly to a wall of the passageway and an axial hole fitting tightly to the rod.
