HWg-WLD
Ethernet Water Leak Detector

HWg-WLD is an IP based water sensor with water leak detection cable. The product features a Web server, SNMP support, e-mail alerts. HWg-WLD can control remote relay outputs over IP (switch remote relay ON/OFF if water leak is detected).

HWg-WLD detects water leaks or water floods along the entire length of the sensing cable. The sensing cable detects even the smallest volume of water, ethylene glycol, or other conductive liquid. HWg-WLD can be ordered in two versions depending on the supply of power (power adapter or PoE IEEE 802.3af).
                                  
The sensing cable detects as little as a few drops of the liquid, and can be used to detect condensation. After flooding, the cable can be dried and reused.

HWg-WLD features a built-in web server and SNMP support. In case of an alarm, the device sends an e-mail or SNMP trap.  

Alarms can be also signaled by switching a remote relay over the Ethernet. When a leak is detected, HWg-WLD activates a relay of a remote Poseidon or Damocles unit (Box-2-Box mode).


Product Parameters

  • Highly sensitive leak detector, 0.4 – 85 m (1.3 – 280 ft) sensing cable length
  • Alarm alerts by e-mail, SNMP trap, or by activating a relay output
  • Detects even the smallest volumes of liquids, sensing cable can be dried and reused

Typical applications involve monitoring of coolant piping in air conditioning systems or water detection around pipes in technical areas. The water leak sensing cable can be wrapped around the piping, suspended under the piping, or laid on the bottom of a pipe duct.

  • Ethernet: RJ45 (100BASE-T)
  • Web: Built-in web server
  • Sensor: 0.4 m (1.3 ft) water sensing cable + 2 m (6.5 ft) leader cable
  • Power: Power adapter or PoE (IEEE 802.3af), depending on type
  • Output: When a water leak is detected, a remote relay is activated over the network (any Poseidon / Damocles)
  • M2M communication protocols: SNMP, XML, Box-2-Box
  • Response to a sensor being flooded / disconnected: E-mail, SNMP trap, remote relay
  • Support for programmers: HWg SDK
