前言:测长仪是广大厂矿企业和基层(县级)计量单位广泛使用的长度计量标准器,一般规格有测量范围为0~500 mm和0~1000mm两种,分辨率一般为0.1μm,广泛使用于长度测量,具有较高的测量精度,使用方便等优点。能不能用测长仪替代测长机对125~500mm的量棒进行测量,是广大基层单位比较关心的技术问题,下面是作者就上述问题进行分析。一.用测长仪测量量棒示值误差测量结果不确定度分析1、概述1.1、测量方法:依据测长仪测量

Foreword: Length measuring instrument is widely used by factories and mines and grassroots (county level) units of measurement. The general specifications are as follows: the measuring range is 0 ~ 500 mm and 0 ~ 1000 mm, the resolution is generally 0.1μm, Used for length measurement, with high accuracy, easy to use and so on. Can use the length measuring instrument to replace the length measuring machine to measure the 125-500mm measuring stick, which is the technical problem that the grassroots units are more concerned about. The following is the author’s analysis of the above problems. One with the measuring instrument measuring rod indication error measurement results of uncertainty analysis 1, an overview of 1.1, measurement methods: measured by the measuring instrument
