WLD -Water Leak Detector

HWg-WLD is a LAN sensor for water leak detection in a 2D area. Water is detected using an easily-extensible sensing cable. HWg-WLD features a built-in web server, SNMP support, and e-mail or SMS alert to water flooding. Early detection and alert to the first drops of water prevents higher costs later.
  • Ethernet: RJ45 (100BASE-T) & PoE Versions available (IEEE 802.3af)
  • WEB: Built-in web server
  • WLD sensing cable A (2m / 10m / 50m)
  • Extension cable – WLD A (5m)
  • Detected liquids: water, ethylene glycol, and other electrically conductive liquids
  • Email, SNMP trap, HWg-Push, activating a remote relay contact
  • SMS Text messages can be sent through a HWg-SMS-GW
  • Box-2-Box support: When a flood is detected, a remote relay output is activated over a LAN
  • M2M communication protocols: SNMP, XML, HWg-Push
  • Dimensions: 66mm x 66mm x 31mm
  • Metal housing, can be mounted on a wall, in a 19" cabinet, or on a DIN rail

Additional Product Information

A correctly installed HWg-WLD cable based water leak detection provides extra time to solve flood problems. The 2D water leak detection can help fix the source of the leak before the costly consequences arise.

HWg-WLD detects water leaks or water floods along the entire length of the sensing cable. By placing the cable near possible flood sources, the whole area can be effectively monitored.

The “WLD sensing cable” reacts to just a few drops of liquid (water, ethylene glycol, ...) and can be also used to detect condensation. After flooding, the sensing cable can be dried and reused. “WLD sensing cable“ can be easily extended with sensing and non-sensing cable segments to create a cost-effective and robust protection of a 2D area against flooding.

As a notable advantage, the “WLD sensing cable” does not produce false alarms when bent, twisted or pinched.

The "HWg-WLD" water leak detector unit can be ordered in a package with a 2m WLD liquid detection cable. Two versions are available – a version powered over the Ethernet (PoE – IEEE 802.3af) or a version with a mains power adapter.

HWg-WLD devices can work together with a central SMS gateway to send text messages (SMS), and can be connected to the SensDesk.com online portal or another software monitoring system by HW group.

  • Water leak detection in an entire 2D area using several sensing cables
  • WLD sensing cable can be easily extended and does not cause false alarms
  • Detects even the smallest volumes of liquids, sensing cable can be dried and reused
