WZCM, WZPM series end special treatment by the thermal resistance element of wire winding, tight towel in front of the thermometer, the axial thermal resistance compared with the general, face thermal resistance more accurately and quickly reflect the face of the actual measured temperature, for to measure bearing temperature or other parts of the face. 

 ● Main technical parameters 
 0 ℃ temperature sensing element when the resistance (R100) and its resistance R0 at 0 ℃ 

 Graduation No. Cu50: R0 = 50 ± 0.050Ω 
 Cu100: R0 = 100 ± 0.10Ω 
 Graduation No. Pt100: R0 = 100 ± 0.12Ω (B grade) 
 Of which: R0 for the component at 0 ℃, the resistance value.
