溫度傳感器元件的正常工作是要滿足其工作條件的，其中之一就是它的工作電流，由于溫度傳感器具有電阻值，當(dāng)電流流過(guò)溫度傳感器元件時(shí)，會(huì)有功率損耗，就會(huì)發(fā)熱，所以為了減小傳感器本身的發(fā)熱引起測(cè)溫誤差，所以要在滿足傳感器正常工作的條件下，盡量減少其本身的發(fā)熱。這就是為什么溫度傳感器要在恒定小電流條件下使用的原因。所以比如鉑熱電阻的常規(guī)工作電流是5MA，但我們推薦的工作電流是1MA。原因就是要減少溫度傳感器元件的自熱引起測(cè)量誤差。電流恒定，其輸出才會(huì)有溫度和電勢(shì)的線性關(guān)系。 </p> <p> 溫度傳感器的插入深度也是容易忽視的一個(gè)問(wèn)題，有些客戶要求插入深度很短但是直徑比較大，這是不合理的，尤其是在高溫的情況下這是不可取的，理論上說(shuō)溫度傳感器的插入深度一般可按實(shí)際需要決定。但*少插入深度不應(yīng)少于溫度傳感器保護(hù)套管直徑的8-10倍。這樣才能保證溫度傳感器性能穩(wěn)定。了解了溫度傳感器的工作電流和插入深度對(duì)我們選定和使用溫度傳感器是很有必要的。如果忽視這兩個(gè)細(xì)節(jié)問(wèn)題很容易造成溫度傳感器性能不穩(wěn)定甚至損壞。河北遠(yuǎn)傳數(shù)顯溫度變送器**變送器有電動(dòng)單元組合儀表系列的和小型化模塊式的，多功能智能型的。</p><div

鍋爐是一種能量轉(zhuǎn)換的設(shè)備，鍋爐本身體積較大，一般應(yīng)用在工廠里居多。鍋爐能夠正常運(yùn)作，不可缺少的就是溫度變送器。鍋爐的使用環(huán)境中需要對(duì)采暖和熱水運(yùn)行的溫度進(jìn)行監(jiān)控。溫度變送器的使用使得鍋爐的控制變的方便和準(zhǔn)確。溫度變送器隨溫度的變化，其內(nèi)部的電阻值也隨之變化，就會(huì)給主控制電路板不同的電流值，就能夠得到鍋爐此時(shí)的運(yùn)行溫度。如果溫度變送器損壞或短路的話，鍋爐也會(huì)自動(dòng)停止工作。一體化溫度變送器具有結(jié)構(gòu)簡(jiǎn)單、節(jié)省引線、輸出信號(hào)大、有反接保護(hù)和限流保護(hù)、工作可靠等優(yōu)點(diǎn)。河北遠(yuǎn)傳數(shù)顯溫度變送器**</p><p

1，控制系統(tǒng)AC電源應(yīng)該來(lái)自于一個(gè)分開(kāi)的系統(tǒng)，與其他設(shè)備和使用分開(kāi); </p> <p> 2，電源在設(shè)計(jì)時(shí)應(yīng)該考慮到初始電流的沖擊，至少能承受10個(gè)周期; </p> <p> 3，控制系統(tǒng)AC接地應(yīng)該建立在隔離變壓器或UPS上，或者在附近溫度變送器; </p> <p> 4，控制系統(tǒng)工作站AC電源應(yīng)該使用專(zhuān)門(mén)的插座; </p> <p> 5，當(dāng)連接現(xiàn)場(chǎng)設(shè)備電源幾個(gè)I/O接口轉(zhuǎn)接器時(shí)，應(yīng)該使用隔離柵條; </p> <p> 6，控制系統(tǒng)AC電源應(yīng)該由隔離變壓器或UPS供給; </p> <p> 7，當(dāng)AC和DC輸入連接到同樣的接線排，接線排必以適當(dāng)?shù)木鏄?biāo)簽標(biāo)出; </p> <p> 8，AC接地線應(yīng)該與載流線型號(hào)相當(dāng)或大一號(hào); </p> <p> 9，預(yù)留一根額外的線或使用一終端盒，以提供測(cè)試點(diǎn)。 </p> <p> 10，接地系統(tǒng)的電阻必須進(jìn)行測(cè)試，以保證接地能滿足控制系統(tǒng)制造商的要求。其實(shí)以上小技巧的也比較使用于平衡流量計(jì)。 </p> <p>
