Bearing heat resistance suitable for power plant with the bearing and other bearing equipment shall be shock temperature measurement.Platinum resistance cross for neutral and oxidizing medium accuracy, good stability, has a certain nonlinear, the higher the temperature the smaller resistance change rate;Copper resistance in the temperature range of a linear relationship between internal resistance value and temperature, temperature line number is big, suitable for corrosive medium, more than 150 susceptible to oxidation.China's most commonly used with R0 = 10 Ω, R0 = 100 Ω and R0 = 1000 Ω to wait for a few kinds, their index number Pt10, Pt100, Pt1000 respectively;Copper resistance with R0 = 50 Ω and R0 = 100 Ω two kinds, their index number for Cu50 and Cu100.Pt100 and Cu50 most widely used.
Thermal resistance is the main technical parameters of the bearing
Electrical exports: M16x1. 5
Connection size: M27x2
Protection grade: IP65
