Abstract
A wireless sensor system includes a sensor assembly and a sensor trigger assembly. The sensor assembly includes a housing configured to be coupled to a device actuated by a rotary actuator, at least two position sensors disposed within the housing, and a power source disposed within the housing and configured to provide power to the at least two position sensors. The housing and the at least two position sensors and the power source disposed therein are coupled to the device such that the sensor assembly is stationary. The sensor trigger assembly is configured to be coupled to and rotate with a rotatable shaft of the rotary actuator. The sensor trigger assembly includes a sensor trigger carrier configured to be coupled to the rotatable shaft and a sensor trigger connected to the sensor trigger carrier. The at least two position sensors are disposed in a first position relative to the sensor trigger to sense a change in a rotational position of the sensor trigger when the rotatable shaft rotates.
