Abstract
In order to break through the limitation of measurement range of traditional Fe-Ni magnetostrictive material adopt a new kind of Fe83Ga17 material
traditional hardware comparison circuit method is discussed. The digital signal processor( DSP)-based signal processing system for magnetostrictive displacement sensor
includes A / D sampling module
FIR filtering module and displacement measurement module is designed in order to handle the problems of the hardware comparison circuit. Considering the error caused by the environmental factor
temperature compensation is designed
measurement result is corrected. The experimental results show that the proposed system can achieve high measurement precision
it has a positive meaning in practical applications for magnetostrictive displacement sensor.
