How Depth Gauges are made?

A depth gauge is a pressure gauge that displays the equivalent depth in water. As the gauge only measures water pressure, there is an inherent inaccuracy in the depth displayed by gauges that are used in both freshwater and seawater due to the difference in the densities of fresh water and seawater.

Most modern diving depth gauges have an electronic mechanism and digital display. Older types used a mechanical mechanism and analogue display. Have you ever wondered how it’s made?
