Water Alarm Sensor Product Description

Global Water’s Water Level Alarm Sensor (WA600) is a solid state water sensor for detecting the presence of conductive solutions, such as water spills, water tank levels, and drainage ponds. The water alarm sensor features two stainless steel electrodes that are positioned at a desired point for liquid detection. When fluid is detected, a relay closes in the water level alarm and the signal can be used to sound an audible alarm or close a switch inside a piece of remote monitoring equipment. The relay output is fully isolated and can handle 2 amps of current.

After the water level alarm sensor is in dry conditions, the detection sensor will automatically reset without requiring additional service. The water level alarm is rugged and durable and requires minimal maintenance.

The Water Level Alarm has many uses, including: surface water monitoring, precision level detection, water level control, high water indication, and submersible marine low level indication. The water alarm sensor can be purchased to trigger an alarm upon contact with water or air (please specify when ordering).
