Water Sensor / Switch AQS Aquaswitch Family

Water Sensor / Switch


The AQS Aquaswitch Family consists of small electronic control relays for detecting rising water levels. Inside a waterproof enclosure, each model features a medium-power relay, which is operated by water reaching the trip level, and can be used to control alarms directly, switch pumps, solenoids, or other equipment. The relay is normally energized when the power supply is switched on and no water is present. When water rises up the side of the box to reach the switching level, the relay drops out. This sequence is failsafe, allowing each model to be used as a water spillage alarm switch or to turn off a valve or an air conditioning unit before the water overflows its containment. No moving parts, switching capacity 250V, 5 Amps.
