Among bonded metal strain gauges, the foil type is more popular than wire type because:
Show Hint
- Error due to transverse strain is much less in foil type
- Gauge factor is much high in foil type
- Foil type is more insensitive to temperature variations
- Error due to transverse strain is much high in foil type
The Correct Option is A
Solution and Explanation
- Reduced transverse sensitivity,
- Better adhesion,
- Higher fatigue life.
Hence, they are widely used in stress and strain measurement.
Top Questions on Transducers for industrial instrumentation
In the force transducer shown in Figure (a), four identical strain gauges S1, S2, S3, and S4 are mounted on a cantilever at equal distance from its base. S1 and S2 are mounted on the top surface and S3 and S4 are mounted on the bottom surface, as shown in the Figure (a). These strain gauges are to be connected to form a Wheatstone bridge consisting of four arms A, B, C, and D, as shown in the Figure (b). From the following options, the correct order to maximize the measurement sensitivity is

The primary coil of a linear variable differential transformer (LVDT) is supplied with AC voltage as shown in the figure. The secondary coils are connected in series opposition and the output is measured using a true RMS voltmeter. The displacement \(x\) of the core is indicated in mm on a linear scale. At the null position \(x = 0\), the voltmeter reads 0 V. If the voltmeter reads 0.2 V for a displacement of \(x = +2\) mm, then for a displacement of \(x = -3\) mm, the voltmeter reading, in V, is:
