用于工业生产中的各种类型的热电偶几乎均呈非线性的变化规律。因此目前大量生产和使用模拟式温度测量仪表,其标尺和记录纸均采用非线性刻度,以实现对温度的正确测量和记录。要实现温度的数字化测量,必须采用线性化器,因为各种类型的热电偶,其mV—T℃曲线均是非线性的。采用线性化器的目的是通过它把热电偶非线性的mV～T℃曲线变成线性的mV—T℃曲线,使温度的数字测量成为可能。 Almost all types of thermocouples used in industrial production show a non-linear variation. Therefore, mass production and use of analog temperature measuring instruments, the scale and recording paper are used non-linear scale, in order to achieve the correct temperature measurement and recording. To digitize the temperature, a linearizer must be used because the mV-T ° C curves for all types of thermocouples are non-linear. The purpose of the linearizer is to convert the non-linear thermocouple mV ~ T ° C curve into a linear mV-T ° C curve, making it possible to digitally measure the temperature.
