Question 558General Subjects - Assistant Engineer70% to pass
Which of the following direct pressure measuring instruments is most appropriately used for measuring most pressures, typically above 10 psig and is by far the most common type?
AI Explanation
The correct answer is B) Bourdon tube pressure gauge.
The Bourdon tube pressure gauge is the most commonly used direct pressure measuring instrument, especially for pressures typically above 10 psig. This is because the Bourdon tube design is rugged, reliable, and well-suited for a wide range of pressure measurements, making it the go-to choice in most industrial and maritime applications.
The other options, such as diaphragm, spiral/helical, and bellows-type pressure gauges, have their own specialized uses, but they are not as versatile or widely used as the Bourdon tube design for the pressure range specified in the question.
