A New Method of Reducing the Measurement Blind Area for MPS

Abstract:

The magnetostrictive position sensor (MPS), which can be used to detect the absolute position of motion objects in a coordinate system, is widely used in industry. It is especially applicable to the conditions of greasy dirt, oil and water. As an important disadvantage for MPS, the measurement blind area (BA) occurs due to the induced electromotive force (EMF) oscillation when the magnetic field of excitation pulse passes the receiving coil. A new structure with two coils is proposed in this paper. Two signals can be obtained by each coil, respectively, and the BA will be improved by different operations between two signals. Finally, the validity of this approach has been proved by experiments.
