HWg-WLD Relay: Water leak detector in 2D surface

HWg-WLD Relay detects a water leak anywhere along the length of the connected sensing cable (2+2m – 6.5+6.5ft). Water leak or cable disconnection is indicated by activating a relay (NO/NC). The sensor can be connected to a Poseidon unit over the 1-Wire UNI bus (RJ11).

To detect water leaks or floods, HWg-WLD Relay uses the “WLD sensing cable A” in lengths of 0.4m to 85m (1.3ft to 280ft). 2m sensing cable is included. Water or any other conductive liquid is detected along the entire length of the sensing cable. The sensing cable can be extended with a non-sensing leader cable by 100m (330ft), total cable length will be 185m (610ft).

The moisture-absorbing sensing cable detects even the smallest volume of water, ethylene glycol, or other conductive liquid.

HWg-WLD Relay can be installed stand-alone using a 12VDC power supply and a relay output, or as a sensor connected to a Poseidon unit over the 1-Wire UNI bus. Relay outputs indicate a detected water leak or cable disconnection.

HWg-WLD Relay is supplied with a 2m (6.5ft) sensing cable.

Features

DOWNLOAD
  • Detects flooding of the 2m sensing cable.
    Water is detected along the entire length of the cable.
  • Signals disconnection of the sensing cable.
  • With using 1-Wire UNI output can be connected as a sensor to any Poseidon2 or Ares unit.
  • WLD Relay can be connected to any DI input by NO/NC relay output.

 

Water sensing cable

  • The sensing cable detects even the smallest volume of water, ethylene glycol, or other conductive liquid anywhere on the total length of the cable.
  • The sensing cable is terminated with connectors.
  • The following can be combined:
    • Water sensing cable WLD - 2m
    • Water sensing cable WLD - 10m
    • Water sensing cable WLD - 50m
    • Prolong cable - 5m
  • The sensing part of the cable can be up to 85m (280ft) long.
  • The cable can be extended anywhere (even between sensing segments) with a 2-wire cable (max 100m – 330ft).
  • The WLD water detection cable is reusable (needs to be dried).
