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?

Correct Answer: Option B — Bourdon tube pressure gauge

The Bourdon tube is the industry standard for direct pressure measurement due to its simplicity, reliability, and wide range. It utilizes a curved metal tube that tends to straighten under pressure, mechanically moving a pointer. It is robust, cost-effective, and suitable for most shipboard applications above 10 psig.
