Question

Suppose we include the lead resistance in the calculation of temperature for an RTD. If R 3 = 5000 ohms, R a = 50 ohms, V 0 = 3 volts, and V = 6.5 volts, what is R? (Type in a one-decimal number.)

Answer 1

Answer:

The temperature coefficient of resistance (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.
