WZCM, WZPM series of face thermal resistance wire element is wound by a special treatment, tight towel in the front end of the thermometer, compared with the general axial thermal resistance, face thermal resistance can more accurately and quickly reflect the actual temperature of the end face of the test for measuring bearing or other parts of the end surface temperatures.
• The main technical parameters
Temperature sensing element resistance value at 0 ℃ (R100) and its resistance at 0 ℃ R0
Indexing number Cu50: R0 = 50 ± 0.050Ω
Cu100: R0 = 100 ± 0.10Ω
Indexing number Pt100: R0 = 100 ± 0.12Ω (B grade)
Where : R0 is the resistance element at 0 ℃ • The measurement range and tolerance. ( Unit : mm)
• Model Specifications NOTE : WZPM-201B with the introduction of elements WZPM-018, A-level precision grade .
