Dorlen’s water sensor cable is a multi-conductor wire with embedded gold-plated sensors every 3 feet. Cable sensors act as extensions of the sensing probes in the Water Alert detector. One or two sensor cables can be connected to any Standard Series Water Alert detector (not for use with VR Series).

  • Only 1/16″ of liquid is needed to activate
  • Gold-plated nickel sensors have maximum corrosion resistance
  • Cable features include end-of-line test button with protective cap

Water Sensing Cable Operation & Construction

The water detection cable is activated by liquid* bridging the adjustable sensors. The cable can detect water film from zero height (water sensors turned out to make contact with the floor) to 1/8″ height (sensors turned all the way in).

*Liquid leakage including solutions of water and ethylene glycol (used in many computer room air conditioning systems).

Dorlen’s leak detection sensing cable is made from ultra-flexible, low-memory cable with a .2″ diameter rubber jacket. Available in three standard lengths of 12, 24, and 36 feet.  Each water leak sensing cable comes with adhesive clips you can use to secure the cable to the floor, if desired.

SC-36 36′ 12

Water Leak Detection Cable Expands Capability of Water Alert

For large areas or perimeter monitoring, water alert sensor cables are your best defense against downtime due to water leaks and floods! Extended-range performance is possible for some environments with these cables as part of your water leak detection system.

Benefits of our Water Detection Rope

A Water Alert sensor cable does not absorb, trap or wick moisture into the cable for detection (unlike coaxial or helical type detection cables). Trapped moisture in other styles of water sensing cables leads to excessive dry out periods, contamination by dissolved particles, and mold and mildew forming, requiring the cable to be uninstalled and cleaned or replaced.

This is why a Water Alert detection cable has the lowest maintenance and longest warranty available for water leak detection equipment.

The low-voltage system is easy to install. Typically installation is done by maintenance personnel with the included instructions. After installation, the system provides years of dependable, maintenance-free operation 24 hours a day.
