24V Water Detector |
The 661
series are small electronic control relays
for detecting a rising water level. Inside a waterproof enclosure
they have a medium-power relay, which are operated by water reaching
the trip level, and can be used to control alarms 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 stop an air
conditioning unit before the water overflows its containment.
