WebSep 13, 2024 · The most common Pt100 RTD used in industry is one that changes resistance at the rate of about 0.385 ohms for every degree Celsius rise in temperature. We know the resistance of a Pt100 sensor at zero degrees Celsius is 100 ohms, so the resistance we would expect at 100 degrees Celsius would be 138.5 ohms. The 385 factor … Web1 RTD Overview RTDs are resistive elements that change resistance over temperature. Because the change in resistance is well characterized, they are used to make precision temperature measurements, with capability of making measurements with accuracies of well under 0.1°C.
