Differential sensor for acquisition of speeds and direction of rotation
The differential magneto-resistive (MR) sensor developed by ROTEC is used to acquire the rotational speeds of ferromagnetic gears. In addition, the direction of rotation can also be detected. The sensor has a two-part design, which allows the sensor alignment and the face sensor distance to the encoder wheel to be adjusted independently of each other.
