摘要
利用AD590冷端温度传感器进行冷端温度测量,经差动比例放大器后,通过A/D转换器芯片—MAX197进行模拟信号到数字信号的转换,实现了金属热处理过程中的温度准确测量。
In this paper, AD590 cold junction temperature sensor for cold junction temperature measurement, the ratio by the differential amplifier, the adoption of A / D converter chip-MAX197 analog signals to digital signals for the conversion of metal heat treatment process to accurately measure the temperature.
