A process device wireless adapter includes a wireless communications module, a metallic housing, and an antenna. The wireless communications module is configured to communicatively couple to a process device and to a wireless receiver. The metallic housing surrounds the wireless communication module and has a first end and a second end. The first end is configured to attach to the process device. In one embodiment, a metallic shield contacts the housing second end such that the metallic shield and the housing form a substantially continuous conductive surface. The antenna is communicatively coupled to the wireless communication module and separated from the wireless communication module by the metallic shield. Preferably, the wireless communications module illustratively includes a printed circuit board that has a length that is greater than its width.

Apparatus to determine the position of a movable member of an actuator operating a valve assembly are disclosed. The movable member of the actuator displaces an actuation arm of a position sensor such that relative displacement occurs between a magnetic flux source and a magnetic flux sensor of the position sensor.

Apparatus to determine the position of an actuator

A valve actuator with an instrument mounting pad and a manifold in a power module and yoke combination for mounting a valve controller instrument without tubing or mounting brackets. A cover encloses the feedback linkage between the actuator and instrument. The actuator includes a second instrument mounting pad and manifold so the power module is reversible to accommodate fail-safe opened or fail-safe closed valve conditions. A valve actuator and instrument combination is no higher than the actuator alone.
