WIRELESS POSITION SENSOR ASSEMBLY FOR A ROTATING ACTUATOR

摘要

A device for wirelessly transmitting a rotation position of an actuator. The device comprises first and second housings. The housing configured for securing to a body of the actuator. An adaptive sleeve may be used for coupling the second housing to a stem of the actuator. The device includes a sensor and a sensor trigger that are mounted in different ones of the first and second housings. The sensor generates a sensor output signal based on a proximity of the sensor to the sensor trigger. The sensor and sensor trigger are mounted such that relative motion between the first and second housings produces a change in the sensor output signal. A radio transmitter transmits the rotational position of the actuator stem based on the sensor output signal.
