The SeaHawk LD1000-M single zone leak detection controller monitors up to 1,000 feet (305 meters) of chemical sensing cable. This unit comes with the leader cable and EOL that are compatible with our chemical sensing cable.
As a stand-alone leak detection controller, the LD1000-M features an audible alarm and three LED indicators. The LD1000-M is Modbus enabled, so you can integrate it via Modbus output into existing monitoring systems. It is ideal for small areas, facilities where the sensing cable is exposed or leaks can be easily located, and areas where the audible/visible alarm can be easily noticed.
Make Sure You Have An Isolated Power Supply!
RLE leak detection controllers, including the LD1000-M, require an isolated power supply. A power supply is not included with the LD1000-M. Purchase an RLE power supply – PSWA-DC-24-ST or WA-AC-24-ST.
