Abstract

Considering the distinct disadvantages, such as complex electric circuit, long debugging period, low testing efficiency, and nonconductivity to the actually promoted application of the traditional permalloy force transducer’s testing system, a new testing system of a permalloy force transducer is proposed according to the characteristics of the output signals. The working principle of the testing system is analyzed. The measuring and controlling section of AT89C52 single-chip microcomputer is studied and the single-chip microcomputer system is discussed from the design and realization of both hardware and software aspects. Economic and practical method is utilized to solve the problem of quantitative research on the piezomagnetic effect of the designed permalloy force transducer. The experimental measurements indicate that the designed testing system is practical and effective. The testing system is of great significance to the quantitative research of the piezomagnetic properties and the repeatability characteristic of piezomagnetic force transducer, which can greatly promote the engineering applications of permalloy piezomagnetic force transducers.
