HYDAC溫度傳感器ETS3226-5-350-400*
HYDAC溫(wen)(wen)(wen)(wen)度(du)(du)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)ETS3226-5-350-400*
溫(wen)(wen)(wen)(wen)度(du)(du)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)與被測(ce)介質的接(jie)觸方(fang)式(shi)分為兩大(da)類:接(jie)觸式(shi)和非(fei)接(jie)觸式(shi)。接(jie)觸式(shi)溫(wen)(wen)(wen)(wen)度(du)(du)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)需要與被測(ce)介質保(bao)持熱(re)接(jie)觸,使兩者進行充分的熱(re)交(jiao)換而達到同一(yi)溫(wen)(wen)(wen)(wen)度(du)(du)。這(zhe)一(yi)類傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)主要有電阻式(shi)、熱(re)電偶、PN結(jie)溫(wen)(wen)(wen)(wen)度(du)(du)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)等(deng)。非(fei)接(jie)觸式(shi)溫(wen)(wen)(wen)(wen)度(du)(du)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)無需與被測(ce)介質接(jie)觸,而是(shi)通過被測(ce)介質的熱(re)輻(fu)射(she)或對(dui)流傳(chuan)(chuan)(chuan)到溫(wen)(wen)(wen)(wen)度(du)(du)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi),以達到測(ce)溫(wen)(wen)(wen)(wen)的目的。
