摘　　要：文章中的微动位移测量装置以MSP430单片机为核心,辅以正弦信号产生电路、差动变压器、直流电机驱动、键盘、LCD显示等电路,实现了精确测量并显示磁棒微动位移的功能。磁棒位移范围为-20mm～+20mm,测量的绝对误差小于1mm;磁棒位移可由键盘设定。测试结果表明该设计是一种较为理想的微动位移测量装置。The instrument is designed with MSP430 MCU （micro controller unit） as its core, including circuits of sinuous signal, LVDT, DC; machine driver, keyboard and LCD in this paper. It realizes the function of accurately measuring and displaying the micromotion displacement of axial magnet. The accuracy of the measurement of axial magnet ranges from -20mm to 20mm with an absolute error less than lmm. The displacement of axial magnet is configurated by keyboard. The test results shot that this device is an ideal instrument to measure micromotion displacement.
