Submersible pressure gauge

Submersible Pressure Gauge (often abbreviated as SPG) is a device used by scuba divers to measure the pressure of compressed air in their scuba tank. The gauge provides a direct readout of the pressure in the tank, usually in bars or pounds per square inch (psi).

Function

The primary function of a submersible pressure gauge is to provide the diver with a clear and accurate indication of the remaining air pressure in their scuba tank. This information is crucial for planning and conducting a safe dive. The gauge is typically connected to the diving regulator via a high-pressure hose and is designed to withstand the high pressure within the scuba tank.

Types

There are two main types of submersible pressure gauges: analog and digital.

Analog gauges use a Bourdon tube gauge mechanism to measure pressure. The pressure from the tank causes the Bourdon tube to straighten, and this movement is transferred to a needle on the gauge face, providing a direct readout of the pressure.

Digital gauges use electronic sensors to measure pressure. The sensor generates an electrical signal proportional to the pressure, which is then converted into a digital readout. Digital gauges often include additional features such as temperature readings, dive time, and depth information.

Safety Considerations

Regular inspection and maintenance of the submersible pressure gauge are essential for safe diving. A faulty or inaccurate gauge can lead to a diver running out of air underwater, which can have serious, potentially fatal consequences. Divers should always check their gauge before and after each dive, and have it serviced regularly by a qualified technician.
