Temperature Coefficient of Resistance of RTD Solution

STEP 0: Pre-Calculation Summary

Formula Used

Temperature Coefficient of Resistance = (Resistance of RTD at 100-Resistance of RTD at 0)/(Resistance of RTD at 0*100)
α₀ = (R₁₀₀-R₀)/(R₀*100)
This formula uses 3 Variables

Variables Used

Temperature Coefficient of Resistance - (Measured in Per Kelvin) - Temperature Coefficient of Resistance is defined as the calculation of a relative change of resistance per degree of temperature change.
Resistance of RTD at 100 - (Measured in Ohm) - Resistance of RTD at 100 is the resistance at 100 celsius for a RTD.
Resistance of RTD at 0 - (Measured in Ohm) - Resistance of RTD at 0 is the resistance at 0 celsius of RTD.

What is RTD?

A Resistance Temperature Detector (RTD) is a device with a significant temperature coefficient (that is, its resistance varies with temperature). It is used as a temperature measurement device, usually by passing a low-level current through it and measuring the voltage drop.

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 α₀ 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 (R₁₀₀) & Resistance of RTD at 0 (R₀) 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).

FAQ

What is Temperature Coefficient of Resistance of RTD?

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 and is represented as α₀ = (R₁₀₀-R₀)/(R₀*100) or Temperature Coefficient of Resistance = (Resistance of RTD at 100-Resistance of RTD at 0)/(Resistance of RTD at 0*100). Resistance of RTD at 100 is the resistance at 100 celsius for a RTD & Resistance of RTD at 0 is the resistance at 0 celsius of RTD.

How to calculate Temperature Coefficient of Resistance of RTD?

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 is calculated using Temperature Coefficient of Resistance = (Resistance of RTD at 100-Resistance of RTD at 0)/(Resistance of RTD at 0*100). To calculate Temperature Coefficient of Resistance of RTD, you need Resistance of RTD at 100 (R₁₀₀) & Resistance of RTD at 0 (R₀).
