Question Paper
1. Write short notes on any four of the following:
R.V.D.T.
Active Transducers
Rotational Potentiometers
Pneumatic Controller
Opto Electronic Transducer
Write down the advantages and disadvantages of electric transducers.
With the help of a schematic diagram, explain the measurement of pressure into electrical signal using Bourdon Tube and L.V.D.T.
Explain the working of a Hall Effect transducer.
Write down any five characteristics of a resistance wire strain gauge.
Write down the advantages of thermistor over thermocouples.
A capacitive transducer uses two quartz diaphragms of area 750 mm^2 separated by a distance of 3·5 mm. A pressure of 900 kN/m^2 when applied to the top diaphragm produces a deflection of 0·6 mm. The capacitance is 370 pF, when no pressure is applied to the diaphragms. Find the value of capacitance after the application of a pressure of 900 kN/m^2.
Enumerate the comparative analysis between strip chart and X-Y recorder.
A quartz piezo-electric crystal having a thickness of 2 mm and voltage sensitivity of 0·055 is subjected to a pressure of 1·5MN/m^2.
Calculate the voltage output.
If the permittivity of the quartz is 40·6 x 10^-12 calculate its charge sensitivity.
Explain general telemetry system with the help of a block diagram.
The tuned circuit in a simple A.M. transmitter uses a 50 MH inductance and 1 nF capacitance. If the oscillator output is modulated by radio frequencies up to 10 kHz, what is the frequency range occupied by side band?
7. Explain the working of spectrum analyzer with the help of a block diagram.
Discuss the basic components of a digital tape recorder.
Explain the working principle of a magnetic tape recorder. Draw its output voltage vs frequency characteristics for the head and amplifier.
Discuss the salient features of computer aided measurements.
Differentiate between analog and digital data acquisition system.
10.(a) Draw and explain the block diagram of a unity feedback system with integral control.
Express the output of the integral controller as a function of integral time and error.
