3.Temperature Sensor for Display Backplane calculation formula

Voltage type (0~5V):

T=V/5×70-20

(T is the measured temperature value (℃), V is the output voltage (V), this formula corresponds to the measurement range -20~50℃)

T=V/5×150-50

(T is the measured temperature value (℃), V is the output voltage (V), this formula corresponds to the measurement range -50~100℃)

Current type (4~20mA):

T=(I-4)/16×70-20

(T is the measured temperature value (℃), I is the output current (mA), this formula corresponds to the measurement range -20~50℃)

T=(I-4)/16×150-50

(T is the measured temperature value (℃), I is the output current (mA), this formula corresponds to the measurement range -50~100℃)

Note: The calculation formulas corresponding to different signal outputs and different measurement ranges need to be recalculated!
