A supervised leak sensor that detects conductive liquid along a cable or zone probe near cleanroom utilities and reports an alarm before water spreads.
- Sensing Cable or Zone Probe
- Supervised Circuit Integrity
- Fast Local Alarm
- BMS Relay Output
مقدمة المنتج
The water leak detection sensor monitors the electrical condition of a floor cable, rope sensor or compact zone probe. Contact with conductive liquid changes the sensing circuit and activates the local controller, while supervision identifies cable breaks or disconnected probes separately. The sensing element can be routed around AHU drain pans, humidifiers, chilled-water lines and raised-floor utility paths. Relay or network output sends leak and trouble states to the BMS so response can begin before water reaches clean finishes or sensitive equipment.
الخصائص الرئيسية
Circuit supervision distinguishes a leak alarm from a broken or disconnected sensor.
Resettable sensing elements can return to service after cleaning and drying.
Separate relay or network states report leak, cable fault and controller health.
مخاوف المنتج للعملاء
A useful leak system must cover the likely water path, remain serviceable and signal cable damage before an actual leak occurs.
A point probe detects water only after it reaches one small location.A sensing cable follows the full perimeter or lowest likely flow path.
A disconnected cable leaves the area unprotected without warning.Supervised end-of-line monitoring creates a distinct trouble alarm for circuit loss.
The sensor must be discarded after a minor clean-water leak.A resettable cable can be wiped, dried and returned to monitoring service.
Water spreads under equipment before staff find the source zone.Zoned circuits and clear controller labels narrow the response area quickly.
