壓力變送器正確接線有哪幾種

發(fā)布日期:2017-12-25 17:51

小編今天重點講講小巧型壓力變送器和2088型壓力變送器怎樣接線,遇到好多客戶壓力變送器買回去之后不知道接哪個端子,怕接錯了,會造成損失,其實很簡單壓力變送器都是二線制4-20MA輸出,兩個端子,一個正,一個負,A接正,B接負。就算A/B接反了也沒事,必竟是24V電源不會燒壞線路板,下面結(jié)合圖形給大家講解如何正確接線

2088型壓力變送器正確的接線方法如  圖(一)

備注:提醒各位電工如果是24V電源A/B兩個端子隨便接都沒事,千萬不能高于24電源這樣會導致線路板,膜片損壞,所以在安裝之前一定多看看說明書,如確實不會接線,要隨時與廠家聯(lián)系。
