Which of the following cannot measure a temperature of 1600°C ?
Correct answer: A. Platinum resistance thermometer
- A. Platinum resistance thermometer
- B. Thermocouple
- C. Photo-electric pyrometer
- D. Radiation pyrometer
Explanation
A platinum resistance thermometer is generally limited to roughly 850 to 1000°C in routine use, whereas thermocouples and optical or radiation pyrometers can measure about 1600°C. Therefore the resistance thermometer cannot normally cover this temperature.
