Which of the following thermocouples can measure the maximum temperature ?
Correct answer: B. Tungsten-molybdenum
- A. Platinum-rhodium
- B. Tungsten-molybdenum
- C. Chromel-alumel
- D. Iron-constantan
Explanation
Tungsten-molybdenum thermocouples withstand higher temperatures than platinum-rhodium, chromel-alumel, and iron-constantan types. This makes option b the suitable high-temperature choice.
