LSZH Sensing Cable - RLE Technologies

Low Smoke Zero Halogen Leak Detection

RLE’s low smoke zero halogen (LSZH) sensing cable reliably detects the presence of water leaks and other conductive fluids. The cable is constructed from non-conductive polymers to help eliminate false alarms, and this cable’s composition is specially formulated to receive a low smoke zero halogen (LSZH) materials classification. In the event of a fire, this cable produces a smaller quantity of smoke, and the smoke that is produced is less dense and less toxic smoke than a non-LSZH sensing cable.

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.

Liquid Cooling Protection

Confidently protect your liquid cooled or air cooled data centers with RLE’s leak detection solutions. All SeaHawk leak detection cables support detection of leaks of Propylene Glycol/water mixtures. We support detection blends with up to 35% Propylene Glycol (by weight) including PG15, PG25 and PG35.

Sensing cables are available in a variety of standard and custom lengths:

3ft (0.91m) – SC-ZH-3
10ft (3.05m) – SC-ZH-10
17ft (5.18m) – SC-ZH-17
25ft (7.62m) – SC-ZH-25
50ft (15.24m) – SC-ZH-50
100ft (30.48m) – SC-ZH-100
Custom Lengths (available upon request) – SC-ZH-CL

With over 20 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.

Technical Notes

Application Guidelines
Our conductive fluid sensing cable is designed to detect conductive fluids, like water and propylene glycol/water blends with 15% (by weight), or higher (including PG15, PG25 and PG35).

If you are trying to detect non-conductive fluids, like pure de-ionized water, gasoline, diesel fuel, or hydraulic oil, this cable will not work.

Annual Maintenance
Has your cable been installed for a while? You may need to test your system. Depending on your environment, systems should be tested at least once a year. The more hazardous or dirty the environment, the more frequently it should be tested. Refer to our Sensing Cable Care and Maintenance Guidelines and learn how to clean your cables and test your system.
