Industrial thermal resistance is used as a temperature measurement sensor. It is usually used in conjunction with display instruments, recorders, and electronic regulators. It can directly measure or control liquid, steam, and gas media in the range of -200℃ to 600℃ during various production processes. The temperature of the solid surface.
According to national regulations, our company produces Pt100 platinum thermal resistors that comply with IEC international standard graduation numbers and Cu50 copper thermal resistors that meet professional standard graduation numbers.

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