Platinum measuring resistor
A platinum measuring resistor is a resistance thermometer used to measure temperature. The most commonly applied platinum resistance thermometers are Pt100 and Pt1000. The designations Pt100/Pt1000 describe the resistor material involved, in this case platinum, and its nominal resistance R0 at a temperature of 0 °C. (R0,Pt100 = 100 Ω / R0,Pt1000 = 1 kΩ). Usually Pt100 and Pt1000 are used, although other resistance values are possible.

Converting Pt100/Pt1000 resistance into temperature
The linear correlation between the electrical resistance of the platinum conductor and the temperature is used to measure the temperature.
