An Approach to the Practicability of Temperature-measuring Circuit Using Thermoelectric Couple
Yu Zhigang · 2001
The paper introduces a new design of hot power plantscommonly used temperature measuring circuit depending on thermoelectric couple. Transforming resistance into voltage signal is accomplished by the adoption of three - line single - arm overhead and the use of the amplification circuit designed for a precision amplifier as an amplification circuit. Newly designed circuit system shows smaller errors ranging from 0 - 630℃ and higher measurement precision.
