Final answer:
The sensitivity of the PT-500 RTD is calculated using the change in resistance over the change in temperature, yielding a value of 1.9 ohms/°C.
Step-by-step explanation:
The sensitivity of a PT-500 RTD can be calculated by determining using the formula S = ΔR/ΔT, where S is the sensitivity, ΔR is the change in resistance, and ΔT is the change in temperature, the change in resistance with respect to the change in temperature. Given the resistance values of 597 ohms at 50°C and 616 ohms at 60°C, we can calculate the sensitivity S using the formula S = ΔR/ΔT, where ΔR is the change in resistance and ΔT is the change in temperature. From the given values, the change in resistance ΔR is 616 ohms - 597 ohms = 19 ohms, and the change in temperature ΔT is 60°C - 50°C = 10°C. Therefore, the sensitivity S is 19 ohms/10°C = 1.9 ohms/°C.
