HWg-WLD

HWg-WLD Water Leak Detector

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).

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).

* Sensing cable can be 0.4 – 85 m (1.3 – 280 ft) long
* 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

Applications

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

* HWg-WLD: Water leak detector - Web server, SNMP, sends e-mail when flooded. Remotely activates a relay, water leak detector, water flood detector, water leak Detection of water leaking from pipes (cable runs along the pipes)

*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.

Basic features

* Ethernet: RJ45 (100BASE-T)
* 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 + 0.4 m (1.3 ft) sensing cable
o The sensing cable detects even the smallest volume of water, ethylene glycol, or other conductive liquid
o The detection cable is reusable
o The detection cable can be supplied in custom lengths
* Power:
o Power adapter
o PoE (IEEE 802.3af) + power adapter (depending on type)

* Supported software
o Configuration: UDP Config - IP address configuration and detection (with DHCP)
o HWg-PD Trigger: Controls other IP devices, redirects alarms to SMS
o HWg-PDMS: Logging of values, graphs, export to MS Excel, reports

Box-2-Box mode

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

* HWg-WLD, water leak detector, water leak detection cable, snmp water sensor 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
