一、前言工业炉内高温气体的测量是对热源的重要测试项目,已为人们重视。目前用于测量高温气体的高温抽气热电偶,由于各项性能指标较差,不能适应迅速发展的热能事业的需要。为此要求研制新型高温抽气热电偶。本文介绍我们研制的短偶高灵敏抽气热电偶。它是在已有 I. Introduction The measurement of high-temperature gas in industrial furnaces is an important test item for heat sources and has drawn great attention from people. Currently used to measure high temperature gas extraction thermocouple, because of poor performance indicators, can not adapt to the rapid development of thermal energy needs. This requires the development of a new high-temperature exhaust thermocouple. This article describes the short couple we developed high sensitivity exhaust thermocouple. It is already there
