End thermal resistance
Description
The end thermal resistance element is made of specially processed wire and is attached to the front end of the thermometer. Compared with the general axial thermal resistance, the end thermal resistance can reflect the actual temperature of the measured end more accurately and quickly, and is suitable for measuring the end temperature of bearing bush or other parts.
● Main technical parameters
Temperature sensing element 0℃ resistance value (R100) and its resistance at 0℃ R0 classification number Cu50 :R0= 50±0.050 ω Cu100 :R0=100± 0.10 ω classification number Pt100:R0=100±0.12 ω (grade B) where :R0 is the component at 0℃ resistance value.
