A hydrostatic test involves pressurising the cylinder to its test pressure (usually 5/3 or 3/2 of the working pressure) and measuring its volume before and after the test. A permanent increase in volume above the tolerated level means the cylinder fails the test and must be permanently removed from service. [3]: sect. 5.7.3
Typical submersible pressure gauge Gas pressure in diving cylinders is measured in both United States customary units psi (pounds per square inch) and metric bar, where 1 bar equals 100 kPa, 0.1 MPa or about 14.5 psi. The face of this US-made cylinder pressure gauge is calibrated in pounds per square inch in red and kilopascals in black.
The first stage regulator body generally has several low-pressure outlets (ports) for second-stage regulators, BCD inflators and other equipment; and one or more high-pressure outlets, which allow a submersible pressure gauge (SPG), gas-integrated diving computer or remote wireless pressure transducer to measure the cylinder pressure.
Submersible pressure gauge, also known as a "contents gauge" is used to monitor the remaining breathing gas supply in scuba cylinders. Dive computer helps the diver to avoid decompression sickness by indicating the decompression stops needed for the dive profile. Most dive computers also indicate depth, time and ascent rate.
Submersible pressure gauge. A scuba regulator first stage has one or two high pressure ports upstream of all pressure-reducing valves to monitor the gas pressure remaining in the diving cylinder, provided that the valve is open. The standard connection is an O-ring sealed 7/16" UNF inside thread. [1] There are several types of pressure gauge.
Feature of some dive computer s to measure cylinder pressure using an integral pressure gauge connected by HP hose to the regulator first stage, or receive data from one or more remote pressure transducers fitted to the HP port of a regulator, and display the pressure on the screen. Other features may also be available using the data.
A display allows the diver to see critical data during the dive, including the maximum and current depth, duration of the dive, and decompression data including the remaining no decompression limit calculated in real time for the diver throughout the dive. Other data such as water temperature and cylinder pressure are also sometimes displayed.
Time penalty in a repetitive dive equivalent to time at depth which would produce the residual nitrogen in the diver at the start of the dive. residual pressure Pressure of the gas remaining in a partly used cylinder from the previous fill. resort dive. Also: introductory dive, introductory diving experience, or trial dive. See: Introductory diving
