High Water Sensor
The BG-HW High Water Sensor detects salt or fresh water and can be easily integrated into any vessel's alarm system. Water in any compartment of a vessel is a potential crisis. Early warnings of water entering the hull or leaking from plumbing is extremely important for the safety of the vessel and passengers.
How It Works
The BG-HW triggers an alarm when high water is detected, once connected to a BG-CP Control Panel or any alarm system. The BG-HW has a 12 or 24 Vdc with 1 amp max alarm output.
The BG-HW is a solid-state device with no moving parts or float switches that can easily be damaged. With IP-67 rated durability, the BG-HW is made with rugged, non-corrosive ABS plastic. The sensor comes with a heavy-duty mounting bracket to attach to a bulkhead or frame with #8x0.75” 316 stainless steel screws. Heavy-duty 14 gauge marine grade wires connect to the BG-JBox Junction Box that should be mounted high on a bulkhead, keeping the connections dry and reliable. The BG-HW has two integrated sensors that ensure a reliable and accurate detection.
