Study on Stress Measurement of the MSG Magnetic Measurement Stress Sensor Based on Composite Properties of Materials

Abstract:

The magnetic measurement stress sensor is the core of the magnetic measurement stress technology. Magnetic measurement stress sensor using magnetostriction and Giant Magneto Resistance (GMR) theory has good correspondence between stress and magnetic, and been validated scientific and reliable through indoor experiments and engineering applications. This paper gives a method on stress sensor anode calibration, verifies the different performance of the sensor based on different materials, makes an analysis of the error between the theoretical calculations and actual measurements of the standard objects, describes the working conditions of using the sensor and indicates a reasonable match is a prerequisite to obtain the desired signal processing results.
