熱電阻溫度變送器中采用的熱電阻是用半導(dǎo)體材料，大多為負(fù)溫度系數(shù)，即阻值隨溫度增加而降低。溫度變化會造成大的阻值改變，因此它是zui靈敏的溫度變送器。熱電阻體積非常小，對溫度變化的響應(yīng)也快。但熱敏電阻需要使用電流源，小尺寸也使它對自熱誤差極為敏感。熱電阻在兩條線上測量的是yiding

人類對溫度變送器的開發(fā)較早，應(yīng)用上也較為廣。從17世紀(jì)初人們開始利用溫度進(jìn)行測量。在半導(dǎo)體技術(shù)的支持下，相繼開發(fā)了半導(dǎo)體熱電偶變送器、熱電阻溫度變送器、PN結(jié)溫度變送器和集成溫度變送器。 </p> <p> 溫度是表征物體冷熱程度的物理量，是工農(nóng)業(yè)生產(chǎn)過程中一個很重要而普遍的測量參數(shù)。溫度的測量及控制對保證產(chǎn)品質(zhì)量、提高生產(chǎn)效率、節(jié)約能源、生產(chǎn)安全、促進(jìn)國民經(jīng)濟(jì)的發(fā)展起到非常重要的作用。由于溫度測量的普遍性，溫度變送器的數(shù)量在各種變送器中居前列。 </p> <p> <br /> 熱電偶溫度變送器一般由基準(zhǔn)源、冷端補(bǔ)償、放大單元、斷偶處理、反接保護(hù)、限流保護(hù)等電路單元組成。河北氣動系統(tǒng)溫度變送器價格</p><p

溫度變送器的重要性與其良好的性能是分不開的。diyi：溫度變送器在現(xiàn)場使用過程中，信號傳輸?shù)目煽啃院?、抗無線射頻電磁干擾能力強(qiáng)；第二：溫度變送器可按實(shí)際應(yīng)用設(shè)定量程，具有更高精度；第三：溫度變送器輸出的信號為標(biāo)準(zhǔn)的電流電壓信號，便于整個系統(tǒng)的標(biāo)準(zhǔn)化；第四：表頭與探針一體化，應(yīng)用靈活；第五：溫度變送器還具有顯示功能，方便現(xiàn)場實(shí)時觀察溫度數(shù)據(jù)及變化。 </p> <p> 在食品的生產(chǎn)流程中，工藝溫度控制有著嚴(yán)格的要求，溫度精細(xì)度的偏差直接影響zui終產(chǎn)品的質(zhì)量優(yōu)劣。使用溫度變送器對溫度準(zhǔn)確、實(shí)時有效的控制與檢測必不可少。河北數(shù)顯溫度變送器聯(lián)系方式</p></p><br /><p>文章來源地址:
