The Murphy Swichgage 30Hg Mechanical Vacuum Gauge A25V-30 is a diaphragm-actuated, vacuum-indicating gage with built-in electrical switch. This switch is used for tripping alarms and/or shutdown devices. The gage has a polycarbonate case and is sealed from the environment. Features a polycarbonate, break-resistant lens and a polished, stainless steel bezel to help protect this rugged, built-to-last instrument. The gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts have a self-cleaning motion to ensure electrical continuity.
Commonly used to measure loading of spark ignition engines through intake manifold vacuum. Can serve as overspeed protection from sudden loss of load on the engine. Can be used anywhere the vacuum source is compatible with port materials. A pulsation dampener (PD2160) is included with each Swichgage to help eliminate pointer flutter.
