摘要
应用高灵敏度位移传感器测量磁致伸缩量。对传感器进行定标,用定标后的位移传感器测量材料在磁场中的磁致伸缩量,测量磁致伸缩量的分辨率优于1μm,测量结果准确度较高,样品更换方便,且输出量为电量,便于计算机实时监测。
The magnetostriction measured by the high sensitivity bridge displacement sensor is designed. Mate rial magnetostriction in the magnetic field is measured by the calibrated displacement sensor. It has the advan rages of the spatial resolution of measurement magnetostriction better than 0. 1μm,higher measurement accu racy, easy sample replacement, the output being power, and easy real time monitoring by computer.
