Calculate RTD Coefficient







Formula

The formula to calculate the RTD coefficient is:

\[ RTD = \frac{R2 - R1}{T2 - T1} \]

Where:

Definition

Example

Let's say the resistance at temperature T1 (R1) is 100 Ω, the initial temperature (T1) is 0 °C, the resistance at temperature T2 (R2) is 138.5 Ω, and the final temperature (T2) is 100 °C. Using the formula:

\[ RTD = \frac{138.5 - 100}{100 - 0} \]

We get:

\[ RTD = 0.385\, \text{Ω/°C} \]

So, the RTD coefficient is 0.385 Ω/°C.
