微小位移检测仪表的设计开发

目前，国内常用的差动变压器式传感器测微仪有指针式和数字式两种，但是存在诸如高精度测量范围小、零位调节不方便、功能单一和通用性差等问题．本文介绍了一种以89C51单片机为核心，采用现有的差动变压器式传感器测头的多功能、智能化测微仪．它具有高精度、智能化、多功能化、操作方便、性能稳定等特点．

Design and Development of Micro-distance Measuring Instrument

At present,the domestic commonly used differential transformer sensors to micro meter have pointer type and digital two kinds,but has such as high precision measurement range small,zero adjustment not convenient,simple function and universal poor etc.This paper introduces a kind of 89C51 monolithic processor as the core,the differential transformer using current head of the sensors micro-distance measuring instrument multifunctional and intelligent.It has high precision,intelligent,muti_function change,conv...
