Final answer:
A helix-shaped Bourdon tube is designed to sense higher pressures than a standard Bourdon tube, which is crucial for accurate pressure readings in high-pressure systems.
Step-by-step explanation:
A Bourdon tube may be manufactured in the shape of a helix for a specific purpose, which is to sense higher pressures than a standard Bourdon tube. When shaped into a helix, the Bourdon tube can handle the increased stress due to the higher pressure it needs to measure. This design allows for accurate pressure readings in industrial and mechanical applications where monitoring high-pressure systems is crucial.
The correct answer to the question is D. Higher pressures can be sensed.
