用光栅测长机测量拉绳位移传感器示值误差的方法探讨

Inquiry into the Method of Measuring Pulling Rope Displacement Sensor Indication Error Based on Length Measuring Grating Machine

本文探讨了将光栅测长机作为标准器,为拉绳位移传感器提供位移输入,直接读取拉绳位移传感器长度尺寸输出量,测量示值误差的具体方法,并对该测量方法进行了不确定度评定,验证了可行性。

This paper discusses the specific method of using grating length measuring machine as a standard, providing displacement input for the drawstring displacement sensor, directly reading the output of the length dimension of the drawstring displacement sensor, and measuring the error of the indicating value.The uncertainty of the measuring method is evaluated, and the feasibility is verified.
