Error Compensation of Measurement System Based on Magnetoresistive Sensors

Abstract:

A measurement system based on the magneto-resistive sensor is described and its error factors and influences are analyzed as well. A reasonable and simple approach is presented to compensate the measurement error from Magneto-resistive Sensor output. Firstly, the principle of the new method is illustrated. Secondly, the steps of the error compensation are introduced. Finally, the test is carried out, results are shown that the maximum angle value of deviation is no more than 2° and compensation method can be used in common measurement system based on magneto-resistive sensors.
