The Correct Option is D
Solution and Explanation
In the field of Instrumentation Engineering, transducers are used to convert physical quantities into electrical signals for measurement and analysis. When measuring static pressure, it is important to understand the characteristics of different types of transducers:
- Semiconductor strain gauge: These are highly sensitive and can measure static pressures effectively. They are suitable due to their ability to provide stable and accurate measurements over time.
- Variable capacitor transducer: It offers good resolution and linearity, making it appropriate for static pressure measurement. This type is known for stability and can be used in such applications.
- Metal wire strain gauge: It also provides stability and accuracy for static measurements due to its ability to measure steady-state strains effectively.
- Piezoelectric transducer: This type is not ideal for static pressure measurement. Piezoelectric transducers are best suited for measuring dynamic changes like vibrations or rapidly changing pressures because they generate electric charge only when subjected to changing stress.
Therefore, the least suitable transducer for static pressure measurement is the Piezoelectric transducer.
