How is maximum system pressure determined?

The determination of maximum system pressure in a Diver Life Support System (DLSS) primarily relies on the relief valve setting. The relief valve is a critical component designed to prevent excessive pressure build-up within the system. If the pressure exceeds the specified limit set by the relief valve, it is designed to open and release pressure to safeguard the system. This setting is crucial for ensuring the safety and integrity of the system during operation.

While environmental temperature can influence system performance, it does not directly determine the maximum pressure. The user manual provides valuable information but typically includes specifications like relief valve settings rather than defining maximum pressure itself. Software control systems may monitor pressures and can alert users to prevailing conditions, but the actual maximum pressure is established by the physical design and settings of components like the relief valve. Thus, relying on the relief valve setting is the most accurate method for determining maximum system pressure in a diver life support context.
