RTD temperature measurement

SOLVED: A resistive temperature detector (RTD) is a sensor used to measure temperature. The RTD's resistance changes as a function of temperature. The PT100 RTD is so called because the device has a resistance of 100 ohms at 0 °C and is made of platinum. The typical design is a thin wire of a certain length wound around a ceramic core.For one such device, we get the following three data points: R(-200 °C) = 18.49 Ω; R(0 °C) = 100.00 Ω; R(200 °C) = 175.84 Ω. Assume there is a linear relati
