传统的电子测微仪存在着精度低、非线性误差大,可靠性差等缺点。本文介绍一种由单片机控制的高精密数显测微仪,它是一种精度高,量测范围大,稳定性好,能够准确测出微小尺寸变化的新一代智能量测仪器。仪器与电感传感器配合,借助相应的测量装置,除能测量工件的几何尺寸及形位误差外,还能用于零件的分选及加工工序时的自动检测。其主要技术指标如下:
The traditional electronic micrometer has the defects of low precision, large nonlinear error and poor reliability. This article introduces a high-precision digital micrometer controlled by a single-chip microcomputer, which is a new generation of intelligent measuring instruments with high precision, large measuring range, good stability and small size changes. Instrument with the inductance sensor with the help of the corresponding measuring device, in addition to measuring the workpiece geometry and shape error, but also for the parts sorting and processing procedures for automatic detection. The main technical indicators are as follows:
