Txheej txheem cej luam

Lub cuab yeej thaiv kev nyab xeeb uas muab hluav taws xob cais rau ob thiab peb txoj hlua xa xov hauv thaj chaw muaj kev phom sij. Lub teeb liab 4 ~ 20mA uas lub cuab yeej xa xov lossis qhov chaw tam sim no tsim tawm los ntawm thaj chaw muaj kev phom sij mus rau qhov tso zis ntawm thaj chaw nyab xeeb, yog li tsav lub nra hnyav hauv thaj chaw nyab xeeb. Rau ob lossis peb txoj hlua xa xov lossis qhov chaw tam sim no, lub cuab yeej thaiv kev nyab xeeb no txhawb nqa kev sib txuas lus ob txoj kev ntawm Hart digital teeb liab uas muab tso rau ntawm 4 ~ 20mA teeb liab thiab muaj lub tswb ceeb toom tawg. Cov khoom no xav tau lub zog hluav taws xob ywj pheej, nrog rau lub zog hluav taws xob cais, cov qhov nkag, thiab cov qhov tso zis.
