Q.3 (a) What is Chromatography? Draw the gas chromatograph setup
with all necessary labeling.
03
(b) Explain Time-of-flight method of Laser type Displacement
Transducer.
04
(c) A strain Gauge with nominal resistance of 200? and Gf =2.0 is
fixed on one flat surface of short column of 2cm ? 2cm cross
sectional area. The column is subjected to an axial force of 100N.
The strain Gauge forms one arm of the bridge with other arms all
equal to 200?. Find the open-circuit output of the bridge excited
by 10V. Given, Young?s modulus of elasticity = 2.2 ? 10

.
07
OR
Q.3 (a) Compare bonded and unbonded strain gauges. 03
(b) Discuss the factors that should be taken care while specifying an
accelerometer for a particular application.
04
(c) A bridge circuit has two fixed resistors and two strain gauges all
of which have a value of 120 ohms. The gauge factor is 2.04 and
the strain applied to twin strain gauges, one in tension and the
other in compression, is 0.000165. If the battery current in the
initial balanced condition of the bridge is 50 mA, determine,
1) The voltage output of the bridge,
2) The sensitivity in volt per unit strain.
If the galvanometer connected to output terminals reads 100 ?V
per scale division & if 1/10th of a division can be read, determine
the resolution.
