Abstract
A wireless valve-position monitor includes a housing having a plurality of possible antenna module mounting ports. A position sensor is within the housing that interfaces to a movable portion of a process-control valve for providing a position detection signal that reflects a position of the process-control valve. A wireless transceiver system including a transceiver coupled to an antenna module is coupled to the position sensor for transmitting a wireless signal that communicates the position of the process-control valve. The antenna module is mounted to one of the plurality of possible mounting ports on the housing.

21. A wireless position monitor, comprising:
-
a housing comprising a plurality of antenna module mounting ports; a position sensor disposed within said housing, the position sensor adapted to interface to a movable portion of a device and configured to supply a position detection signal representative of a position of said device; a wireless transceiver coupled to receive the position detection signal from said position sensor and configured to generate a wireless signal that includes at least a signal representative of the position detection signal; and an antenna module mounted to one of said antenna module mounting ports, the antenna module comprising an antenna element coupled to said transceiver and configured to emit the wireless signal. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

23. A method of determining a preferred antenna module mounting location for a wireless position monitor that includes a housing having a plurality of antenna module mounting ports and a wireless position sensing and transmission system disposed within the housing, the wireless position sensing and transmission system comprising a transceiver configured to generate a wireless signal and an antenna module that includes an antenna element coupled to the transceiver and configured to emit the wireless signal, the method comprising the steps of:
-
individually mounting said antenna module to each of said plurality of different antenna module mounting ports; while said antenna module is individually mounted in each of said plurality of different antenna module mounting ports, measuring a signal strength of said wireless signal at a remote location; determining a preferred antenna module mounting port from said plurality of different antenna module mounting ports based on the measured signal strengths; and mounting said antenna mounting port to the preferred antenna module mounting port. - View Dependent Claims (19)
