主要特點：
● 采用硅橡膠或環氧樹脂密封結構，因此耐震、耐濕，適合在現場環境中安裝使用；
● 現場安裝在熱電偶，熱電阻的接線盒內使用，直接輸出4-20mA、0-10mA的輸出信號。這樣既節約了昂貴的補償導線費用，又提高了信號遠距離傳輸過程中的抗干擾能力；
● 熱電偶變送器具有冷端自動補償功能；精度高、功耗低，使用環境溫度范圍寬，工作穩定可靠；
● 適用范圍廣,即可以與熱電偶,熱電阻形成一體化現場安裝結構,也可以作為功能模塊安裝在檢測設備中和儀表盤上使用:
工作原理：
熱電偶或熱電阻傳感器被溫度轉換成電信號,再將信號送入變送器的輸入網絡,該網絡包含調零和熱電偶補償等相關電路。經調零后的信號輸入到運算放大器進行信號放大，放大的信號一經V/I轉換器運算處理后以DC4-20mA電流輸出；另一路經A/D轉換器處理后到表頭顯示。變送器的線性化電路有兩種，均采用反饋方式。對熱電阻傳感器，用正反方式校正，對熱電偶傳感器，用多段折線逼近法進行校正。一體化數字顯示溫度變送器LCD顯示的采用兩線制方式輸出。
