| Abstract: | The paper introduces a new design of hot power plantscommonly used temperature maeasuring 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. |
