一、前言:近年来,微处理机在热处理领域的应用正广泛开展,而快速、准确的测温则是实现热处理工艺过程自动化控制的首要问题。热电偶由于具有测温点小,测温范围广测温精度高,反应速度快及结构简单,使用方便等优点,因而是各种热处理炉最常用的测温元件。利用微机把热电偶的热电势信号转换成温度真值有两个途径。一是将热电偶分度表中所列的数据全部存入微机存贮区,用数据
First, Foreword: In recent years, the application of microprocessors in the field of heat treatment is widely carried out, and rapid and accurate temperature measurement is the primary problem to realize the automatic control of the heat treatment process. Thermocouple temperature sensor with a small, wide range of temperature measurement temperature accuracy, fast response and simple structure, easy to use, etc., which is the most commonly used heat treatment furnace temperature components. There are two ways to convert thermocouple thermocouple signal into temperature true value by computer. First, the thermocouple indexing table all the data listed in the computer storage area, with data
