溫度變送器已經(jīng)越來越多的應用到石油、化工、化纖;紡織、橡膠、建材;電力、冶金、醫(yī)藥;食品等工業(yè)領域現(xiàn)場測溫過程控制。而熱電阻與熱電偶溫度變送器是常用的。 </p> <p> 溫度變送器采用熱電阻、熱電偶作為測溫元件，從測溫元件輸出信號送到變送器模塊，經(jīng)過穩(wěn)壓濾波、運算放大、非線性校正、V/I轉(zhuǎn)換、恒流及反向保護等電路處理后，轉(zhuǎn)換成與溫度成線性關(guān)系的4～20mA電流信號輸出。溫度變送器將溫度變量轉(zhuǎn)換為可傳送的標準化輸出信號，將被測主回路交流電流轉(zhuǎn)換成恒流環(huán)標準信號，連續(xù)輸送到接收裝置。 </p><p> 溫度變送器的熱惰性： </p> <p> 溫度變送器是一種使用熱電阻等元器件將溫度信號轉(zhuǎn)化為電信號的儀器儀表。溫度變送器的研發(fā)過程是復雜和嚴苛的，很多因素都影響著終溫度變送器的測量。熱惰性就是其中一個重要因素。熱惰性是指在一定時間對某材料加一定量的熱，材料表面的溫度改變快慢的性質(zhì)。溫度變送器的熱惰性其實就是溫度變送器里，熱電阻或者熱電偶的熱惰性。由于熱電阻或者熱電偶的熱惰性使儀表的指示值落后于被測介質(zhì)溫度的變化，在進行快速測量時這種影響尤為突出。解決這一現(xiàn)象通常的做法是采用導熱機能好的材料，管壁薄、內(nèi)徑小的溫度探針和保護套管。溫度變送器熱惰性引起的誤差在測量中有很大的影響，尤其是在精密測量的時候一定要注意，我們要盡量避免溫度變送器熱惰性引起的誤差，或者采取適當?shù)难a償來消弱這種誤差。溫度變送器是將溫度變量變換為可傳送的規(guī)范化輸出信號，它的應用非常廣。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河北小型溫度變送器**,溫度變送器" src="https://tyunfile.71360.com/WaterMark/UploadFile/xalunqian/637329352318056640/3713289.png"></div><p> 在溫度變送器的使用中，常常出現(xiàn)多種多樣的故障問題，常見的就是無輸出故障，只要用戶對其進行適當?shù)恼{(diào)試，一般就可以解決了。用戶適當?shù)膶W習溫度變送器的無輸出調(diào)試，有利于用戶解決故障問題。下面是溫度變送器出現(xiàn)無輸現(xiàn)象的原因。 </p> <p> 1、查看溫度變送器的電源是否接反了，電源正負極是不是接正確了。 </p> <p> 2、測量變送器的供電電源，是否有24V直流電壓;必須保證供給變送器的電源電壓≥12V(即變送器電源輸入端電壓≥12V)。如果沒有電源則應檢查回路是否斷線、檢測儀表是否選取錯誤(輸入阻抗應≤250Ω)等等。 </p> <p> 3、如果壓力變送器是帶表頭的，需要檢查表頭是否損壞(可以先將表頭的兩根線短路，如果短路后正常，則說明是表頭損壞)，如果是表頭損壞，則需另換表頭。 </p> <p> 4、如果是壓力變送器出現(xiàn)問題，可將電流表串入24V電源回路中，檢查電流是否正常。如果正常則說明變送器正常，此時應檢查回路中其他儀表是否正常。 </p> <p> 5、電源是否接在變送器電源輸入端，把電源線接在電源接線端口上。 </p> <p> 溫度變送器無輸出調(diào)試的原因就是以上幾種情況。當然，在實際應用中，可能會出現(xiàn)很多問題導致溫度變送器不能正常工作，在安裝和使用前，建議大家要認真的去拍出故障。變送器如果由兩個用來測量溫差的傳感器組成，輸出信號與溫差之間有給定的連續(xù)函數(shù)關(guān)系。故稱為溫度變送器。河北小型溫度變送器**</p><p
