product description

Industrial thermal resistance as a temperature measurement sensor, usually display instruments, recorders and electronic regulator supporting the use of it can directly measure or control the various production process -200 ℃ -600 ℃ range of liquid, vapor and gas media and The temperature of the solid surface.

According to state regulations, our company produces Pt100 platinum resistance thermocouples in accordance with IEC international standard numbering, and Cu50 copper heat resistance according to professional standard dividing number. It is a unified design type thermal resistance.

Main Specifications: Temperature measurement range and tolerance

Thermal resistance category Temperature range ℃ Division number Allowable deviation △ t ℃ WZP type platinum resistance -200~ 420 Pt100 Class B (-200 ~ 420 ℃ tolerance ± (0.30 + 0.005 | t |) Class A (-200 ~ 550 ℃) Tolerance ± (0.15 + 0.002 | t |) WZC type copper resistance -50~ 100 Cu50 -50 to 100 ° C Tolerance ± (0.3 + 6.0 × 10-3t) Note: where 't' for the temperature sensing element of the absolute value of the measured temperature.

The resistance value (R100) of the thermal resistance temperature sensing element at 100 ° C and the ratio of its resistance R0 at 0 ° C: (R100 / R0) Sub-degree Pt100: A grade R0 = 100 ± 0.06Ω Class B R0 = 100 ± 0.12Ω R0 / R100 = 1.3850 Sub-degree No. Cu50: R0 = 50 ± 0.05Ω R0 / R100 = 1.428 ± 0.02
