Thermocouple in a thermal well behaves as a true ________________?
Correct answer: C. Multiple first order system
- A. First order system
- B. Second order system (overdamped)
- C. Multiple first order system
- D. Second order system (underdamped)
Explanation
The thermal well and the thermocouple each contribute a thermal time constant, so the combined response is modeled as a cascade of first-order elements. It is therefore a multiple-first-order system rather than a single first- or second-order response.
