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)Q4. (7 marks) I. Section (A) (mark 7) Temperature sensor operates as

Q4. (7 marks) 1. 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 715C, 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)
