Air Pressure Switches, Current Sensors & Gas Detectors

Air pressure differential switches can be used to detect disruption in air flow and automatically shut off the gas supply as part of a gas interlock system. Current sensors can be used as an alternative to air pressure differential switches in commercial gas interlock systems to monitor the air current from extraction fans. Gas detectors are used to monitor emissions such as the build up of carbon dioxide or natural gas, and can be used as part of an interlock system to trigger an audible alarm and isolate the gas solenoid valve.
