Course Code: AE304
Course Name: INDUSTRIAL INSTRUMENTATION
PARTA
Answer any two full questions, each carries 15 marks.
Explain the concept, along with circuit diagram, of using RTD for temperature

measurement.

Using suitable diagram explain the working of fluidic temperature sensor.
Explain the working of a Bourdon gauge. What is special about its cross section?
With the help of a neat sketch, explain how a McLeod gauge helps accurate
