We are a leading Manufacturer of fire survival cable, water leak detection cable, tracetek wld cable, bonton fire survival armoured cable, delton jelly field armored cable and heat shrink cable jointing kit from Delhi, India.
The WD-XS range are designed to detect water leaks either at localised points using the WD-PS point sensor or larger areas with the WD-CS cable sensor. The surface of the WD-RS rain sensor can be heated to avoid false detection alarms resulting from dew forming, the detector can be swivelled on the mounting bracket and is held in place by a wing nut.
All these sensors must be used with the WD-AMX range of modules and should not be directly connected to a BMS controller. As the cable excitation used is an isolated AC signal which ensures the detector cable will not be subject to oxidation or erosion over time, avoiding the degradation problems associated with DC systems.
