電源電路

　　溫控電路中需要直流電壓的器件為運(yùn)算放大器及電子信息顯示模塊。該電壓由220V交流電壓經(jīng)整流濾波后加。至三端穩(wěn)壓器輸出得到。其電路如圖2所示。

　　2．2 輸入溫度信號(hào)放大及溫度補(bǔ)償電路

　　用感溫元件鎳硌一鎳鉻K型熱電偶作溫度傳感器來采集溫度信號(hào)，溫度信號(hào)為mV級(jí)，實(shí)際測(cè)量時(shí)需經(jīng)過放大處理。熱電偶測(cè)量溫度信號(hào)受工作端溫度 和自由端環(huán)境溫度影響，所以測(cè)量中需要加補(bǔ)償信號(hào)消除環(huán)境溫度變化對(duì)溫度測(cè)量的影響。具體電路如圖3所示。
