Signal Processing of Giant Magnetostritive Force Sensors

Abstract:

Based on the analysis of the principle of giant magnetostrictive force sensor, the signal processing system of the sensor has been designed. First, this paper designs manual and automatic working mode for the giant magnetostrictive force sensor. Using SCM as a micro-controller, its peripheral interface circuits hardware system have been designed, including signal amplification circuit, analog to digital (A/D) conversion interface circuit, LED display interface circuit, determinant keyboard input interface circuit and imposing force control circuit. This system is able to display the numerical value of the imposed force. The software of the whole system is designed. Experiments are conducted to show that the signal processing system works well, which is important to practical application of the giant magnetostritive force sensor.
