一體化溫度變送器是溫度傳感器與變送器的完美結(jié)合，它可以將-200 ～ 1600℃范圍內(nèi)的溫度信號(hào)轉(zhuǎn)換為二線制4 ～ 20mA DC 的電信號(hào)傳輸給顯示儀、調(diào)節(jié)器、記錄儀、DCS等，實(shí)現(xiàn)對(duì)溫度的精確測(cè)量和控制。溫度變送器采用熱電偶、熱電阻作為測(cè)溫元件，從測(cè)溫元件輸出信號(hào)送到變送器模塊，經(jīng)過(guò)穩(wěn)壓濾波、運(yùn)算放大、非線性校正、V/I 轉(zhuǎn)換、恒流及反向保護(hù)等電路處理后，轉(zhuǎn)換成與溫度成線性關(guān)系的4 ～ 20mA 電流信號(hào)，RS485 數(shù)字信號(hào)輸出。是現(xiàn)代工業(yè)現(xiàn)場(chǎng)、科研院所溫度測(cè)控的更新?lián)Q代產(chǎn)品，是集散系統(tǒng)、數(shù)字總線系統(tǒng)的必備產(chǎn)品。

           ●一體化設(shè)計(jì)，結(jié)構(gòu)簡(jiǎn)單合理
           ●二線制輸出。傳輸距離遠(yuǎn)，抗干擾能力強(qiáng)
           ●冷端、溫漂、非線性自動(dòng)補(bǔ)償
           ●測(cè)量精度高，長(zhǎng)期穩(wěn)定性好
           ●溫度模塊內(nèi)部采用環(huán)氧樹(shù)脂澆注工藝，適應(yīng)于各種惡劣和危險(xiǎn)場(chǎng)所使用
           ●通用性強(qiáng)，可直接替換普通裝配式熱電偶、熱電阻
           ●采用熱電偶溫變，可免用補(bǔ)償導(dǎo)線，降低成本
           ●液晶、數(shù)碼管、指針等多種指示功能方便現(xiàn)場(chǎng)適時(shí)監(jiān)控
           ●現(xiàn)場(chǎng)環(huán)境溫度＞ 70℃時(shí)，變送器和現(xiàn)場(chǎng)顯示儀可采用分離（隔離）式安裝
