HW group NB-WLD

NB-WLD is a remote monitoring unit with one WLD zone (Water Leak Detection), internal battery, and NB-IoT (NarrowBand IoT) connectivity (sim card can be included). Water is detected along the entire length of the WLD sensing (detection) cable.

NB-WLD is powered by an internal battery or an external power adaptor. There is 1 zone of WLD sensing cable (total wiring length up to 60m with non-sensing prolong cable included).

Thanks to fast detection of the first water drops anywhere on the WLD sensing cable can NB-WLD prevent substantial damages to the infrastructure.

NB-WLD is an IoT Monitoring device, which means it has to be connected to any SensDesk Technology-based portal. All the SMS / Email alerts, PDF reports, and central device management is realized from the portal.

Manufacturer provides limited free of charge portal service (HWg-cloud.com) and paid service (SensDesk.com), check the Portal providers for other available portals.


Applications and usage:

• Detection of water leaking from pipes (WLD sensing cable can run alongside the pipes)
• Liquid penetration from the next room (sensing cable laid alongside the walls)
• Water in Datacenters (under raised floors / above suspended ceilings)
• Detection of water leaks under A/C outlets
• Liquid detection in buildings

WLD sensing cable features

• Liquid is detected along the entire length of the WLD sensing cable.
• WLD sensing cable Type A detects even the smallest volume of water, ethylene glycol, or other conductive liquid anywhere on the total length of the cable.
• WLD sensing cable is re-usable (flooded cable can be cleaned, dried & used again)
• Zone detection states: OK / Flooded / WLD cable disconnected
• No Bend limit: WLD sensing cable Type A is not limited by any bending radius. 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.

SensDesk Technology portal is required

The SensDesk Technology is a portal solution from the HW group to manage remote sensors and devices (only for HW group products). Portals offer a central overview of all the values and provide a variable combination of features like sending the alarms, reporting, history record, outputs into the Open API etc.

• NB Device has to be connected to any SensDesk Technology-based portal (SaaS).
• There are several Portal providers available, users can migrate the device between their portals.
• Manufacturer provides a limited free portal (HWg-cloud.com) as the default pre-configured option.
• Even the free & limited portal service (HWg-cloud.com) can send email alerts and offers basic remote device management.
• One of the available portals is paid service www.SensDesk.com
• Several subscription plan options
• SMS / Voice call alerts to any mobile phone
• Graphs / MultiGraphs (data history)
• PDF reports
• Email alerts/alarm escalation
• Open API: All sensor values are available via XML / SNMP protocols
