Tech Tip: Inside Submersible Pressure Gauges

As divers, we often make important decisions based on the cylinder pressures indicated by a very simple mechanical device — our submersible pressure gauge (SPG). A quality SPG typically has an all brass chrome plated housing with a tempered mineral glass face and features a beryllium copper coiled Bourdon tube mechanism. The rack and pinion movement provides the greatest degree of accuracy and reliability. The Bourdon tube bends slightly as the SPG is pressurised. As the tube flexes, the indicator needle rotates around the dial in relationship to the movement of the tube.
