主要特點(diǎn)：
● 采用硅橡膠或環(huán)氧樹(shù)脂密封結(jié)構(gòu)，因此耐震、耐濕，適合在現(xiàn)場(chǎng)環(huán)境中安裝使用；
● 現(xiàn)場(chǎng)安裝在熱電偶，熱電阻的接線(xiàn)盒內(nèi)使用，直接輸出4-20mA、0-10mA的輸出信號(hào)。這樣既節(jié)約了昂貴的補(bǔ)償導(dǎo)線(xiàn)費(fèi)用，又提高了信號(hào)遠(yuǎn)距離傳輸過(guò)程中的抗干擾能力；
● 熱電偶變送器具有冷端自動(dòng)補(bǔ)償功能；精度高、功耗低，使用環(huán)境溫度范圍寬，工作穩(wěn)定可靠；
● 適用范圍廣,即可以與熱電偶,熱電阻形成一體化現(xiàn)場(chǎng)安裝結(jié)構(gòu),也可以作為功能模塊安裝在檢測(cè)設(shè)備中和儀表盤(pán)上使用:
工作原理：
熱電偶或熱電阻傳感器被溫度轉(zhuǎn)換成電信號(hào),再將信號(hào)送入變送器的輸入網(wǎng)絡(luò),該網(wǎng)絡(luò)包含調(diào)零和熱電偶補(bǔ)償?shù)认嚓P(guān)電路。經(jīng)調(diào)零后的信號(hào)輸入到運(yùn)算放大器進(jìn)行信號(hào)放大，放大的信號(hào)一經(jīng)V/I轉(zhuǎn)換器運(yùn)算處理后以DC4-20mA電流輸出；另一路經(jīng)A/D轉(zhuǎn)換器處理后到表頭顯示。變送器的線(xiàn)性化電路有兩種，均采用反饋方式。對(duì)熱電阻傳感器，用正反方式校正，對(duì)熱電偶傳感器，用多段折線(xiàn)逼近法進(jìn)行校正。一體化數(shù)字顯示溫度變送器LCD顯示的采用兩線(xiàn)制方式輸出。
