摘　　要：针对位移传感器校准问题,提出了一种现场校准方案。该方案利用光栅尺作为基准,结合直线导轨和快速安装夹具,构建了一种便携式的位移传感器校准装置,解决了因位移传感器不便独立拆卸,无法单独送检的问题。通过验证该装置的误差和重复性,证明其校准效果可靠。同时,还对该装置在位移传感器校准过程中的测量不确定度分量进行了分析,为实际应用提供了理论支持。This paper proposes an on-site calibration method for displacement sensors.The method utilizes a grating ruler as a reference,combined with linear guides and quick-install fixtures,to construct a portable displacement sensor calibration device.This addresses the issue of inconvenience in independently dismantling displacement sensors and the inability to send them for separate inspection.By verifying the error and repeatability of the device,its reliable calibration effect is proven.Additionally,this paper analyzes the measurement uncertainty components of the device during the displacement sensor calibration process,providing theoretical support for practical applications.
