Pt100resistance4-20 mA

YUNYI PT100 temperature probe sensor is a high-precision temperature measurement component based on the platinum resistance temperature measurement principle. The “PT” in its name represents platinum material, while “100” indicates a resistance value of 100Ω at 0°C. Leveraging platinum’s highly linear resistance-temperature relationship, it achieves precise temperature measurement across the range of -200°C to +850°C. PT100 sensors have become one of the most mainstream and reliable temperature measurement solutions in industrial applications due to their exceptional accuracy, outstanding stability, and excellent repeatability.
