WLD sensing cable Type A 50 m for leak detection, extension without connecting cable - HW group 600466

Large raised floor areas and long pipe routes need leak detection without gaps and with as few joints as possible. The Type A WLD sensing cable covers 50 m in one piece and reports a few drops of conductive liquid at any point. That single cable uses more than half of the 85 m of sensing cable allowed per zone.

Benefits

• Detection along the full length: water and other conductive liquids such as ethylene glycol trigger an alarm anywhere along the 50 m.
• No bend radius: the cable keeps working even when knotted, so installers need no special training.
• No false alarms from movement: micro movements of neighbouring cables are ignored, and a mechanically disconnected cable is reported as a separate state.
• Cost-effective extension: combine sensing and non-sensing sections up to 185 m per zone (60 m on NB-WLD).
• Reusable: a flooded cable can be cleaned, dried and put back into service.

Applications

• Large raised floor areas in data centers
• Server rooms with several rack rows and cooling units
• Liquid cooling with CDUs and quick disconnects, detection of glycol-based coolants along distribution lines
• Long pipe routes in plant rooms and industrial facilities
• Storage rooms and archives

Compatibility

• WLD2 with 4 WLD zones
• SD-WLD with 1 WLD zone
• NB-WLD with 1 WLD zone, limited to 60 m zone length
• Sensor WLD Relay 1W-UNI
• Perseus
• J-clips 600492 for fixing the cable to the floor
