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.
