HARRIS Gas Switchover System

Working Mechanism

• Each gas source has a pressure regulator that reduces the pressure of the gas to a safe and usable level.
• The switchover manifold consists of a set of valves and sensors that control the flow of gas from the sources to the application.
• Pressure sensors are installed in the system to monitor the pressure of the gas in each source and the manifold.
• When the gas pressure in the primary source drops below a certain level, the system's pressure sensors will detect the pressure drop.
• The system's control logic will then automatically switch the valves to allow gas flow from the secondary source.
• Once the secondary source is activated, the pressure sensors will continue to monitor the gas pressure from both sources.
• When the pressure in the primary source restores, the system will automatically switch back to the primary source.
