An RTD temperature sensor has a resistance of 110 Ω at 0°C and a resistance of 121 Ω at 100°C. What is the temperature of the sensor if its resistance is measured to be 115 Ω?
A. 27.7°C
B. 45.5°C
C. 60.9°C
D. 72.2°C
Answer:B
An RTD temperature sensor has a resistance of 110 Ω at 0°C and a resistance of 121 Ω at 100°C. What is the temperature of the sensor if its resistance is measured to be 115 Ω?
A. 27.7°C B. 45.5°C C. 60.9°C D. 72.2°C
Explanation: To determine the temperature of an RTD temperature sensor when its resistance is measured to be 115 Ω, we can use the concept of linear interpolation between the two known data points: resistance at 0°C and resistance at 100°C.
