Temperature resistance
Temperature resistance
Medical, electrical, industrial, temperature calculation, resistance calculation and other high-precision temperature equipment are widely used.
Working principle
PT100 is a platinum thermistor, its resistance value will change with the change of temperature. 100 after Pt means that its resistance is 100 ohm at 0 ℃ and 138.5 ohm at 100 ℃. Its industrial principle: when PT100 is at 0 ℃, its resistance value is 100 ohm, its resistance value will rise with the temperature, and its resistance value will increase at a constant speed.

Component
The common pt1oo temperature sensing elements include ceramic elements, glass components and mica components. They are made of platinum wires wound on the ceramic framework, glass framework and mica framework respectively, and then processed by complex processes
Thin film platinum resistance
Thin film platinum resistor: platinum is sputtered on ceramic substrate by vacuum deposition thin film technology. The film thickness is less than 2 μ M. the Ni (or PD) lead wire is fixed with glass sintering material, and the thin film element is made by laser resistance modulation.
