2D surface water leak detector
wld

HWg-WLD is a network-enabled water leak detector with a water-absorbing sensing cable. HWg-WLD features a built-in web server, SNMP support, and e-mail alert to water flooding.

HWg-WLD can remotely control a relay output over the network (a relay is switched when a water leak is detected along the sensing cable).

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).

Product Parameters

Product Parameters

  • Ethernet: RJ45 (100BASE-T) (PoE version IEEE 802.3af)
  • Web: Built-in web server
  • M2M communication protocols: SNMP, XML, Box-2-Box
  • Remote output: When a water leak is detected, a remote relay is activated over the network (any Poseidon / Damocles)
  • Water flood detector: 2 m (6.5 ft) leader cable +2 m (1.3 ft) sensing cable
  • SMS Gateway: Device can send SMS by external "HWg-SMS-GW" without any software.
  • Power:
    • HWg-WLD: Power adapter
    • HWg-WLD PoE: PoE (IEEE 802.3af) + power adapter (depending on type)

Supported software:

  • Configuration: UDP Config - IP address configuration and detection (with DHCP)
  • HWg-PD Trigger: Controls other IP devices, redirects alarms to SMS
  • HWg-PDMS: Logging of values, graphs, export to MS Excel, reports
  • CapTemp: Visualization on a map, control of outputs, alarm redirection to SMS
  • Third-party SNMP software
  • For programmers: HWg-SDK contains interface descriptions and examples of using M2M protocols in several programming languages

Usage example

Usage example

usage

HWg-WLD can directly control relay outputs over the network. No additional software is necessary.

  • Supports any Poseidon or Damocles unit
  • State is transferred upon changes as well as periodically (default period is 30s). Uses XML over http.
  • The output must be in the "Manual" mode (no local condition for activating the output)
  • The user configures the remote device IP & port and the remote output ID (ID 151 = Output 1, 154 = Output 4)
  • If the relay is write-protected with a password, the user sets the password for controlling the relay
  • Output control can be tested with the TEST button

Applications

WLD-picture

Typical applications involve monitoring of coolant piping in air conditioning systems or water detection around pipes in technical areas.

  • Detection cable laid along the walls
  • Under raised floors
  • Above suspended ceilings
  • Detection of water leaks in drip trays
  • Detection of water leaks under A/C outlets

The water leak sensing cable can be wrapped around the piping, suspended under the piping, or laid on the bottom of the pipe duct.
