The corresponding relationship between thermistor value and temperature is as follows:

P3.png

T1:Test target temperature, unit: ℃;

T2:Reference point temperature, unit: ℃, The typical value of the reference temperature within -20~70℃ is 10 or 40℃, and the reference temperature close to the target temperature should be selected.

R1:T1 corresponding thermistor resistance value, unit: kΩ;

R2:T2 corresponding thermistor resistance value, unit: kΩ;

B:T2 corresponding thermistor resistance value, unit: kΩ;

B:Between-20~70deg,the typical B value is 3019.6±60.

Notice:

a) During TEC installation, pay attention to the new resistance introduced by the external electrical structure. If the new resistance exceeds

When TEC resistance is 10%, the I-V curve needs to be recalibrated.

b) It is recommended to switch on TEC in a way with small connection resistance. If welding is required, short circuit is required

Grounding protection, welding temperature ≤250℃, welding duration < 10s;
