WZKPJ--236一體化熱電阻溫(wen)度(du)變送器

●產品簡介

WZPKJ--236一(yi)體化(hua)熱(re)電阻(zu)溫(wen)度(du)變(bian)送器是(shi)DDZ-S系列儀表中的(de)現場安(an)裝式溫度(du)變(bian)送(song)單元。它(ta)(ta)采用(yong)二(er)線傳(chuan)送(song)方(fang)式（兩根導線作為電(dian)(dian)源輸(shu)入(ru)，信號輸(shu)出的(de)公(gong)用(yong)傳(chuan)輸(shu)線）。將熱(re)電(dian)(dian)阻信號變(bian)換成(cheng)與(yu)(yu)輸(shu)入(ru)電(dian)(dian)信號或被測溫度(du)成(cheng)線性的(de)電(dian)(dian)流或電(dian)(dian)壓輸(shu)出信號，變(bian)送(song)器(qi)可以(yi)安(an)裝于熱(re)電(dian)(dian)阻的(de)接線盒內(nei)與(yu)(yu)之形成(cheng)一體(ti)化(hua)(hua)結構。它(ta)(ta)作為新一代(dai)測溫儀表可廣泛應用(yong)于冶金、石油(you)化(hua)(hua)工(gong)、電(dian)(dian)力、輕工(gong)、紡織、食品、國防以(yi)及科研等工(gong)業部(bu)門(men)。

WZPKJ--236一體化鎧裝熱電(dian)阻變送器采用環氧樹脂(zhi)密封結(jie)構，因此抗震、耐溫(wen)，適合(he)在(zai)惡劣(lie)現場(chang)環境中(zhong)安(an)裝(zhuang)使(shi)用。現場(chang)安(an)裝(zhuang)于熱電(dian)(dian)阻、熱電(dian)(dian)偶(ou)(ou)的(de)接線(xian)盒內，直接輸出電(dian)(dian)流或電(dian)(dian)壓信號，這樣既(ji)省去較貴的(de)補償導線(xian)費用，又提(ti)高了信號長距(ju)離傳送過(guo)程中(zhong)的(de)抗力。精度(du)(du)高、功(gong)耗(hao)低、使(shi)用環境溫(wen)度(du)(du)范(fan)圍寬(kuan)、工作(zuo)穩(wen)定可(ke)(ke)靠。量程可(ke)(ke)調，并具有線(xian)性化(hua)較正功(gong)能(neng)，熱電(dian)(dian)偶(ou)(ou)溫(wen)度(du)(du)變送器具有冷端自動補償功(gong)能(neng)。應(ying)用面廣，既(ji)可(ke)(ke)與熱電(dian)(dian)偶(ou)(ou)、熱電(dian)(dian)阻形成一體化(hua)現場(chang)安(an)裝(zhuang)結(jie)構，也(ye)可(ke)(ke)作(zuo)為(wei)功(gong)能(neng)模塊安(an)裝(zhuang)入(ru)檢測設備中(zhong)。
