What is the principle of operation of a strain gauge pressure transducer?
A. A flexible diaphragm is deformed by the applied pressure, which changes the resistance of a strain gauge.
B. A piezoelectric crystal is compressed by the applied pressure, which generates an electrical signal.
C. A fluid-filled tube is distorted by the applied pressure, which moves a magnet in a coil of wire.
D. A piston is moved by the applied pressure, which changes the capacitance of a capacitor.
Answer:A

Explanation: A strain gauge pressure transducer works on the principle that a flexible diaphragm will deform when exposed to pressure, which will change the resistance of a strain gauge attached to the diaphragm. This change in resistance is converted into an electrical signal that can be processed by a computer or other electronic device.
