管道(dao)/浸入(ru)式(shi)傳(chuan)感器(qi)(qi)，用于(yu)(yu)測量空(kong)氣(qi)溫(wen)度(du)和(he)其他氣(qi)體介(jie)質（例如(ru)在通(tong)(tong)風和(he)空(kong)調系統中）。結(jie)合(he)熱(re)(re)套管袋，它可以用作浸入(ru)式(shi)溫(wen)度(du)傳(chuan)感器(qi)(qi)。用于(yu)(yu)加熱(re)(re)，通(tong)(tong)風和(he)空(kong)調系統的氣(qi)態介(jie)質中的溫(wen)度(du)測量。免工具打開(kai)，關閉和(he)接線以及可拆卸(xie)電(dian)(dian)纜入(ru)口確保安裝(zhuang)快速簡便。特別是對于(yu)(yu)2線導體版本的無源傳(chuan)感器(qi)(qi)，必須考慮電(dian)(dian)源線的線電(dian)(dian)阻。如(ru)有必要，必須通(tong)(tong)過后續電(dian)(dian)子(zi)設備補償導線電(dian)(dian)阻。由于(yu)(yu)自發(fa)熱(re)(re)，導線電(dian)(dian)流(liu)會(hui)影(ying)響(xiang)測量精度(du)，因此不應超過1 mA。

當使用(yong)(yong)冗長的(de)(de)連(lian)接線（取決于所使用(yong)(yong)的(de)(de)橫(heng)截面）時(shi)，由于公共GND線的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)降（由電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)流和線電(dian)(dian)(dian)阻引起），測(ce)量(liang)(liang)結果可能會(hui)出(chu)現偏差。在(zai)這種(zhong)情(qing)況下(xia)，必(bi)須將(jiang)2根(gen)GND線連(lian)接到傳(chuan)感(gan)器(qi)(qi) - 一根(gen)用(yong)(yong)于電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)(ya)，一根(gen)用(yong)(yong)于測(ce)量(liang)(liang)電(dian)(dian)(dian)流。帶(dai)傳(chuan)感(gan)器(qi)(qi)的(de)(de)傳(chuan)感(gan)裝置應在(zai)測(ce)量(liang)(liang)范圍的(de)(de)中間(jian)運(yun)行，以避免測(ce)量(liang)(liang)端點(dian)出(chu)現偏差。傳(chuan)感(gan)器(qi)(qi)電(dian)(dian)(dian)子元件的(de)(de)環境(jing)溫度應保(bao)持恒定。傳(chuan)感(gan)器(qi)(qi)必(bi)須在(zai)恒定電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)(ya)（±0.2V）下(xia)運(yun)行。打開/關閉電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)(ya)時(shi)，必(bi)須避免現場(chang)電(dian)(dian)(dian)涌。
