Angle sensor is an important sensor used in instrument measurement, industrial automation, aviation and navigation. The measurement principles are diverse and commonly used are encoder disc type, grating type and potentiometer type, but these sensors have some problems in practical applications, such as encoder disc type, grating type, etc. High precision, high resolution, angle measurement The range is wide, but the volume is large, the subsequent measurement circuit is more complicated, the potentiometer type structure is simple, but the contact is easy to wear, and the output characteristic is stepped and the resolution is not high.
Our company collects and processes sensor signals and develops a non-blind-angle magnetoresistive angle sensor with a measuring range of 0-360° and an accuracy of 12 digits. The sensor uses magnetic field as the medium, has no contact, and has no time limit for its service life. The angle information can be accurately obtained after power-on, which is an absolute reading, which can realize multi-angle measurement with high accuracy, high resolution, low cost and small volume.
