End-face thermal resistance
Description
The end-face thermal resistance element is wrapped by specially treated wire and is close to the front end of the thermometer. Compared with the general axial thermal resistance, the end-face thermal resistance can reflect the actual temperature of the end face measured more correctly and quickly. It is suitable for measuring the end face temperature of the bearing bush or other parts.
● Main technical parameters
The resistance value of temperature sensing element at 0℃ (R100) and its resistance at 0℃ R0 classification Cu50 :R0= 50±0.050Ω Cu100 :R0=100± 0.10Ω classification Pt100:R0=100±0.12Ω(B grade) where :R0 is the resistance value of the element at 0℃.
● Measuring range and tolerance (unit: mm)
