Question

The least suitable transducer for static pressure measurement is:

• A. semiconductor strain gauge
• B. variable capacitor transducer
• C. metal wire strain gauge
• D. piezoelectric transducer

Hint:

Remember: Piezoelectric = dynamic. For static measurements, choose strain gauges or capacitive sensors instead.

Answer 1

The Correct Option is D

Piezoelectric transducers are highly sensitive to dynamic (changing) forces, which makes them ideal for dynamic pressure measurement.
However, they are not suitable for static pressure measurement because the charge generated by the mechanical stress tends to dissipate over time.
On the other hand, devices like strain gauges and capacitive transducers can hold the measurement under constant conditions and are more appropriate for static pressure.
Therefore, among the given options, the piezoelectric transducer is the least suitable for static pressure measurement.
