Product overview
WZ - fabricated thermal resistor as temperature measurement sensor, usually display instrument, recorder and electronic regulator, assembled heat resistance can be directly measured or control in the production of various - 200 ℃ to 600 ℃ within the scope of the liquid, steam and gas medium and temperature on the surface of the solid. According to the provisions of the state, my company production in line with the IEC international standard score number of Pt100 platinum thermal resistance and conform to the degree of professional norm Cu50 copper heat resistance of two groups of prefabricated, unified design type thermal resistance.
The main technical indicators:
Temperature measurement range and tolerance
Thermal resistance category | ℃ temperature range | Degree, | The allowable deviation delta t ℃ |
Platinum resistance type WZP | - 200 ~ 600 | Pt100 | B (200 ~ 600 ℃? - tolerance + / - (0.30 + 0.005 | t |) |
A level (200 ~ 550 ℃) tolerance + / - (0.15 + 0.002 | t |) | |||
WZC type copper resistance | - 50 ~ 100 | Cu50 | - 50 ~ 100 ℃ tolerance + / - (0.3 + 6.0 x 10-3 t) |
Note: type "t" as the temperature component in the measured temperature of the absolute value. | |||
Thermal resistance temperature sensing element 100 ℃ resistance (R100), and it is in the resistance of the 0 ℃ R0 ratio (R100 / R0)
A grade dividing Pt100: R0 = 100 + 0.06 Ω
Class B R0 = 100 + 0.12 Ω
R0/R100=1.3850
Dividing Cu50: R0 = 50 + / - 0.05 Ω
R0/R100=1.428±0.02
