Platinum resistance, as the main method of thermal resistance, is one of the components that uses the resistance value of a conductor or semiconductor to measure temperature as it changes with temperature.

PT100 refers to a thermal resistance with a nominal resistance R0 at 0 ℃ and a resistance value of 100 Ω  while PT1000 refers to the resistance value of the nominal resistance R0 at 0 ℃

A thermal resistance of 1000 Ω.

Platinum resistors are widely used in mechanical manufacturing, HVAC, and other fields due to their high accuracy, good temperature measurement stability, no need for reference points, and compatibility with various structures in various fields such as temperature control equipment, food hygiene, medical devices. and new energy.
