ABSTRACT:
The shaft monitoring device for monitoring the rotation of a shaft about a longitudinal axis is comprised of an encoder, a stationary housing, and a shaft-engaging member rotatably attached to the stationary housing. The encoder has a target and a proximity sensor located within the housing. The housing is mounted to a stationary object such as a block-type bearing supporting one end of the rotating shaft to be monitored. A first end of the shaft-engaging member is placed against the shaft. The first end firmly engages the rotating shaft, thereby allowing the shaft-engaging member to rotate in unison with the rotating shaft. As the shaft rotates, the target attached to a second end of the shaft-engaging member also rotates in unison. As the target passes over the end of the proximity sensor, the sensor reads the presence of the target and closes a switch. Each time the switch is closed, a pulse is generated. This pulse or signal is carried by a signal cable to a signal receiving device which can read the signals to determine the speed, direction of rotation, position, or rotation count of a shaft.
