Question: Q4. (7 marks) I. Section (A) (mark 7) Temperature sensor operates as a first-order system and is stated to have a time constant of 0.11
Q4. (7 marks) I. Section (A) (mark 7) Temperature sensor operates as a first-order system and is stated to have a time constant of 0.11 s. If it is initially at a temperature of 500C and suddenly exposed to an environment temperature of 7l5C, how long will it take to indicate a temperature of 617C? (3 marks) 1. If the temperature sensor of Prob. above is exposed to a harmonic temperature source, for what frequency range will its amplitude response be within 10 per-cent? (2 marks) 2. What will be the phase shift and time delay under these circumstances? (2 marks)
