Bilge Alert, High Water Alarm 12V - Johnson Pump
The Bilge Alert™ system uses a patented Mirus field effect detector cell, which produces a micro-electrical field that detects disruptions caused by water and fluids. When activated the sensor will trigger a 100db piezo alarm and an LED light on the control panel.
The sensor measures a small 26 mm wide x 64 mm long x 5 mm thick (1.04 x 2.5 x 0.2 in) which makes it very easy to mount. Detector cells are totally sealed, are never in contact with the water, will not corrode and are not affected by oil or foreign debris.
