Product details
Prefabricated thermistor
Industrial Pt100 thermistor CU50 thermistor is commonly used as a temperature measurement sensor, usually in conjunction with display instruments, recorders, and electronic regulators. It can directly measure or control the temperature of liquid, steam, gas media, and solid surfaces within the range of -200 ℃ -600 ℃ in various production processes
According to national regulations, our company produces two types of assembled and uniformly designed thermistors: Pt100 platinum thermistors with IEC international standard division numbers and Cu50 copper thermistors with professional standard division numbers.

The ratio of the resistance value (R100) of the thermistor temperature sensing element at 100 ℃ to its resistance R0 at 0 ℃: （R100/R0）
Division number Pt100: Class A R0=100 ± 0.06 Ω
B-class R0=100 ± 0.12 Ω
R0/R100=1.3850
Index number Cu50: R0=50 ± 0.05 Ω
R0/R100=1.428 ± 0.02
