WLD relay installation
Sensor WLD Relay can be used as a Standalone WLD sensor (power + relay output) or as a 1W-UNI sensor connected to any STE2, Poseidon2, HWg-Ares, or other HWg devices.
WLD sensing cable
- WLD sensing cable detects liquid along the entire length of the sensing cable
- even the smallest volume of water, ethylene glycol, or other conductive liquid
- re-usable (cable can be cleaned, dried & used again)
- Zone detection states: OK / Flooded / WLD cable disconnected
- The „WLD sensing cable A“
- supplied in length from 2m to 50m (up to 185 meters/zone in total)
- can be extended by non-sensing WLD prolong cable A
- terminator is required at the end of the zone (included in the default WLD sensing cable A - 2+2)
WLD sensing cable features
- No Bend limit: WLD sensing cable Type A is not limited by any bending radius. The sensing cable can be knotted and still works properly.
- No Twist limit: WLD sensing cable Type A can be twisted as any other electrical cable.
- No Grip limit: Water detection functionality is not limited by point pressure within a reasonable range.
WLD sensing cable components
- Connection cable - 2m (Green terminal block, 2m, Terminator)
- WLD Sensing cable A - 2m / 10m / 50m
- WLD prolong cable A - 5m
WLD sensing cable vs. Flood detectors
Flood detection requires the installation of a detector in a place where water will likely be located after leakages from various sources of flooding (cracked water pipes, glycol from the cooling system, wastewater). The Flood detector has to get entirely flooded to trigger an alarm. WLD sensing cable detects liquid along the entire length of the sensing cable and even the smallest amount of liquid can send the alert.
HW group offers several products that provide ideal solutions for flood and water leak detection. See the table below and discover the best solution for your situation:
