The NGS is a rugged level switch built for harsh environments. All wetted parts are made of 316-Ti stainless steel. The SPDT switch is activated by a permanent magnet external to the switch housing so that no exposure occurs between the process media and the switch internals. This mode of operation results in a very reliable switch that requires no external power to operate. The 10A mechanical switch will directly operate most electrical loads such as relays, solenoid valves and motor starters. Common applications include minimum or maximum level monitoring of tanks or vessels when only a side-mounted installation is possible.
