●Calculation Formula
Voltage mhando (0～5V):
T=V / 5 × 70 -20
(T ndiyo yakayerwa tembiricha kukosha (℃), V ndiyo inobuda magetsi (V), iyi fomula inoenderana nechiyero chechiyero -20 ~ 50 ℃)
T=V / 5 × 150 -50
(T ndiyo yakayerwa tembiricha kukosha (℃), V ndiyo inobuda magetsi (V), iyi fomula inoenderana nechiyero chekuyera -50 ~ 100 ℃)
Yazvino mhando (4～20mA)
T=(I-4)/ 16 × 70 -20
(T ndiyo yekuyera kukosha kwekushisa (℃), ini ndiri kubuda ikozvino (mA), rudzi urwu runoenderana nechiyero chekuyera -20 ~ 50 ℃)
T=(I-4)/ 16 × 150 -50
(T ndiyo yakayerwa kukosha kwetembiricha (℃), ini ndiri kubuda ikozvino (mA), iyi fomula inoenderana nechiyero chechiyero -50 ~ 100 ℃)
Ongorora: Iwo maformula ekuverenga anoenderana neakasiyana masaini mabudiro uye akasiyana kuyerwa zviyero zvinoda kuverengerwazve!
