一前言早在五十年代末到七十年代初期,人们就研究出了负温度系数热敏电阻温度特性曲线的线性化方法,也探讨过互换性的问题。本刊81年第二期发表的“测温热敏电阻互换性的探讨”一文,作者更系统的阐述了当前解决热敏电阻互换性问题的三个途径,即调阻法、配对法和补偿法。但在这些文献中,都是把线性化和互换性两个问题分开来描述的。本文将在电阻——温度特性曲线线性化的基础上,进行线性化参数计算与分析,从而探讨出一种新的互换方法,这里称作“线性化互换法”。
A preface As early as the late fifties to the early seventies, people have developed a linear method of temperature characteristic curve of negative temperature coefficient thermistor, and also discussed the problem of interchangeability. The second issue of 81 published in the “temperature thermistor interchangeability,” a text, the author more systematically elaborated on the current solution to the problem of thermistor interchangeability three ways, namely, drag regulation method, matching method And compensation law. However, in these documents, both the linearization and interchangeability are described separately. In this paper, based on the linearization of the resistance-temperature characteristic curve, the linearization parameter calculation and analysis are carried out to explore a new exchange method, which is called “linearized exchange method” here.
