Wireless device having movable antenna assembly and system and method for process monitoring

[0009]In one exemplary embodiment of the present disclosure, a wireless device having a movable antenna assembly can be operably coupled to a sensing device that is operable to capture data representative of one or more parameters of a process device or sample. Since the movable antenna assembly antenna can be used for both transmitting and receiving, the wireless device can be a transmitter, receiver, or a transceiver. The wireless device can have a housing with a mounting structure for rigidly connecting the wireless device with respect to the process device or sample, and an antenna assembly having a movable connection with the housing. The antenna assembly can be moved with respect to the housing. The movable connection can maintain a hermetic seal and an explosion-proof flame path of the housing and the antenna assembly. In one embodiment the wireless device is a wireless transmitter or transceiver which wirelessly transmits the sensor data using the antenna assembly to a remote receiver.

However, control steps are often highly dependent upon measured or otherwise sensed data from the sensors, and inaccuracies or delays in receipt of the data can have a significant effect on the ability to control the process.

Under certain arrangements (e.g. structures and the like in the path of transmission) or environmental conditions, for a given
