Abstract: An apparatus for sensing a process variable, includes a housing and a process variable sensor that has an electrical characteristic that changes with a process variable. A first sealed portion is configured to be exposed to a process fluid. The process variable sensor is mounted relative to the first sealed portion. A second sealed portion couples the first sealed portion to the housing. The second sealed portion has at least one seal that fluidically isolates the first sealed portion from the housing.
