    Abstract: A process device (34, 360, 500, 600) includes a controller (36, 362) and a wireless communications module (32, 366, 506). The wireless communications module (36, 366, 506) is coupled to the controller (36, 362). A power generation module (38, 365, 508, 602, 604, 620) is provided to generate electricity for the process device (32, 366, 506). The power generator module (38, 365, 508, 602, 604, 620) can be disposed within the process device (32, 366, 506) or it can be a separate unit coupled to the process device (32, 366, 506).

    Abstract: A field device (36) is coupled to a process through at least one process interface element (50, 102, 172, 200). The process interface element (50, 102, 172, 200) may be a field device flange, a manifold, or a process flange. The process interface element (50, 102, 172, 200) has a temperature sensor (106) attached thereto, and is adapted to receive a thermal source (104, 124, 156, 178, 206). In one embodiment, the thermal source (104, 124, 156, 178, 206) is one or more electrical heaters (104, 156, 206). In another embodiment, the thermal source is thermal transfer fluid tracing (126, 174) through the process interface element (50, 102, 172, 200). A controller (108) is coupled to the temperature sensor (106) and is adapted to control the heat applied to the process interface element (50, 102, 172, 200) based upon the temperature of the process interface element (50, 102, 172, 200) measured by the temperature sensor (106).

    Abstract: 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.

    Abstract: An in-line pressure transmitter (10) for sensing an absolute or gage process pressure of a process fluid includes an in-line process coupling (14). The coupling has a mounting member (16) which includes a substantially flat mounting face (18) and a bore generally aligned with an isolation diaphragm assembly (30). The member (16) is configured to mount to a flat process coupling.
