Measuring Temperature with RTDs – A Tutorial
where R100 is the resistance of the RTD at 100°ÊC, and R0 is the resistance of the RTD at 0°ÊC. For example, a 100ÊΩ platinum RTD with α = 0.003911 will measure 139.11ÊΩ at 100°ÊC. Figure 1 displays a typical resistance-temperature curve for a 100ÊΩ platinum RTD.-300 0 300 600 900 0 100 200 300-100 400 Temperature (˚C) Resistance ...

cdn-learn.adafruit.comNov 15, 2021 · For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 or
