Coding Strategy: This value is the converted to a temperature using the polynomial equation from the RTD specifications for the respective sensor, and the Callendar-Van Dusen equation. Finally, we will output the result to a numeric indicator and a temperature chart on the front panel.
Resistance Temperature Detector (RTD)

Learners study animations to see the connection between temperature and resistance as they examine the operation of an RTD. A table is used to convert resistance readings to the corresponding temperatures. A brief quiz completes the activity.
