●Tsarin Lissafi
Nau'in wutar lantarki (0～5V):
T=V / 5 × 70 -20
(T shine ƙimar zafin jiki da aka auna (℃), V shine ƙarfin fitarwa (V), wannan dabarar tayi daidai da kewayon ma'auni -20 ~ 50 ℃)
T=V / 5 × 150 -50
(T shine ƙimar zafin jiki da aka auna (℃), V shine ƙarfin fitarwa (V), wannan dabarar tayi daidai da kewayon ma'auni -50 ~ 100 ℃)
Nau'in Yanzu (4 ~ 20mA)
T=(I-4)/ 16 × 70 -20
(T shine ma'aunin zafin jiki (℃), Ni ne fitarwa na yanzu (mA), wannan nau'in yayi daidai da kewayon ma'auni -20 ~ 50 ℃)
T=(I-4)/ 16 × 150 -50
(T shine ƙimar zafin jiki da aka auna (℃), Ni ne fitarwa na yanzu (mA), wannan dabarar ta dace da kewayon ma'auni -50 ~ 100 ℃)
