Chinyezi cha nthaka:
Mtundu wamagetsi (0 ~ 5V kutulutsa):
R = V / 5 × 100%
(R ndiye chinyezi cha nthaka ndipo V ndi mtengo wamagetsi otulutsa (V))
Mtundu wapano (4 ～ 20mA zotuluka):
R = (I-4) / 16 × 100%
(R ndiye kuchuluka kwa chinyezi cha nthaka, ine ndiye mtengo wapano (mA))
Kutentha kwa nthaka:
Mtundu wamagetsi (0 ~ 5V kutulutsa):
T = V / 5 × 70-20
(T ndiye mtengo woyezera kutentha (℃), V ndi mtengo wamagetsi otulutsa (V), fomula iyi imafanana ndi muyeso woyezera -20 ~ 50 ℃)
Mtundu wapano (4 ～ 20mA)
T = (I-4) / 16 × 70 -20
(T ndiye muyeso woyezera kutentha (℃), Ine ndiye kutulutsa panopa (mA), fomulayi imagwirizana ndi muyeso woyezera -20 ～ 50 ℃)
