ANGULAR POSITION SENSING DEVICE AND METHOD FOR MAKING THE SAME

摘要

The present disclosure provides a sensor for sensing an angular position range of a rotatable shaft. The sensor comprises an indicating circuit for generating a binary state signal having a first signal state and a second signal state in response to the rotation of a bipolar magnet device that is attached on the rotatable shaft (108) and adapted to rotate together with the rotatable shaft; and an adjusting circuit for adjusting the binary state signal to compensate variations of operating conditions of the sensor. The binary state signal is in the first signal state when the rotatable shaft is within the angular position range and the binary state signal is in the second signal state when the rotatable shaft is beyond the angular position range. The width and/or offset of binary state signal of the sensor can be adjusted to compensate in response to operating condition variations.
