How to Calculate Temperature Coefficient of Resistance of RTD?
Temperature Coefficient of Resistance of RTD calculator uses Temperature Coefficient of Resistance = (Resistance of RTD at 100-Resistance of RTD at 0)/(Resistance of RTD at 0*100) to calculate the Temperature Coefficient of Resistance, The temperature Coefficient of resistance of RTD (denoted as TCR) for resistance temperature detectors (denoted by αo), is normally defined as the average resistance change per °C over the range 0 °C to 100 °C, divided by the resistance of the RTD, Ro, at 0 °C. Temperature Coefficient of Resistance is denoted by α_{0} symbol.
How to calculate Temperature Coefficient of Resistance of RTD using this online calculator? To use this online calculator for Temperature Coefficient of Resistance of RTD, enter Resistance of RTD at 100 (R_{100}) & Resistance of RTD at 0 (R_{0}) and hit the calculate button. Here is how the Temperature Coefficient of Resistance of RTD calculation can be explained with given input values -> -0.005435 = (47-46)/(46*100).
