RLE Conductive Fluid Sensing Cable


RLE’s conductive fluid sensing cable provides optimal protection for your facility when you don’t know exactly where fluid infiltration might occur


By running a cable around the perimeter of a room and/or in a serpentine pattern under a floor, you know whenever as little as a dropper-full of water touches that cable. RLE’s patented design assures fast response time while minimizing or eliminating false alarms due to dust, debris, or other objects on the cable.


And with over 9 million feet (2,743,200 meters) of RLE’s conductive fluid sensing cable installed world wide, you can rest easy knowing that your facility is protected by the industry standard for reliable leak detection.


RLE’s orange sensing cable (SC) reliably detects the presence of water leaks and other conductive fluids. It’s one of our hallmark products, and RLE Technologies has held the patent for this particular cable since 2000.


RLE’s conductive fluid sensing cable is:

    • Durable – manufactured with an abrasion-resistant polymer core, which increases strength and durability. Definitely stands up to foot traffic!
    • Flexible – easily bends around corners and wraps around pipes, while resisting bends and kinks.
    • Resists False Alarms – engineered specifically to resist contamination and constructed from non-conductive polymers to help eliminate false alarms!
    • Quick to Install – each end of the cable contains mating connectors – this makes it easy to install new systems and to add lengths of cable to existing systems.
    • Easy to Clean – when it’s visibly dirty, clean it quickly with Dawn dish soap or rubbing alcohol. No special cleaners or cleaning systems required.
    • Fast Drying – gently wipe the cable dry, and it’s ready to detect the next leak.

Plus – all of our sensing cables are manufactured and assembled in the USA.


With over 9 million feet of leak detection sensing cable installed in systems around the globe, you can’t beat the durability or reliability of our leak detection sensing cables.
