Applications of linear Hall-effect sensors on angular measurement

The non-contact type application on the permanent magnet and linear Hall-effect sensor gauging rotary system is introduced in this paper. For such a contactless case, there is no wear. This provides a longer life span in association, and in particular, high reliability to achieve continuous use. The main component of the angular position estimation system is the linear Hall-effect sensor. The angle gauge depends on the Hall voltage at the rotation of the magnetic induction. The advantage of the system is its reliable operation in special environmental conditions, such as high vibration, humidity, or dust. Higher accuracy and precision will be achieved, as shown by the experimental results, and it can be widely used in the angular measurement field.
