    摘要： A pressure module includes a sensor assembly with tubes extending from a pressure sensor to fluid isolator members. The pressure sensor is contained in a cavity in a module housing. The module housing includes support members joined by joints to the fluid isolator members to provide barriers to leakage of process fluids into the cavity. Threaded process inlets on a bottom outside surface of the module housing couple the process fluids to the fluid isolator members through process passageways in the module housing.

    摘要： A field device is coupled to a process through at least one process interface element. The process interface element may be a field device flange, a manifold, or a process flange. The process interface element has a temperature sensor attached thereto, and is adapted to receive a thermal source. In one embodiment, the thermal source is one or more electrical heaters. In another embodiment, the thermal source is thermal transfer fluid tracing through the process interface element. A controller is coupled to the temperature sensor and is adapted to control the heat applied to the process interface element based upon the temperature of the process interface element measured by the temperature sensor.

    摘要： A microwave level gauge for measuring a level of a process material in a tank includes a ceramic seal and a microwave conductor. The ceramic seal is disposed adjacent to an opening in the tank and adapted to isolate circuitry from the process material. The microwave conductor is electrically coupled to the circuitry and extends through the hermetic seal and into the process material in the tank. The ceramic seal and an isolating adapter cooperate to isolate the microwave conductor from the process fluid and from external forces.
