HW group - WLD-Echo Set

Water leak detector with two sensing cable zones, audible alarm, and relay output for early leak detection along WLD cables.

Product information "HW group - WLD-Echo Set"

WLD-ECHO is a compact water leak detector supporting two external sensing cable zones. It detects even a few drops of conductive liquid anywhere along the sensing cable (up to 185 m) and provides early warning via a built-in audible alarm and relay output.

Powered by either 2× AA batteries or an external power supply, WLD-ECHO offers flexible installation in data centers, server rooms, and other technical facilities.

Fast detection requires no standing water level, ensuring reliable long-term monitoring. The device also signals sensing cable disconnection or damage. Zone 2 can be disabled when not in use.

With its dry-contact relay output, WLD-ECHO can be easily integrated into security or monitoring systems.

WLD liquid sensing (rope) cables provide continuous water leakage detection along their entire length. Water sensing cables cover larger areas and react much faster, even to just a few drops of water. However, water sensing cables require more careful installation.
