SERIES WD3 WATER LEAK DETECTOR Battery or External Powered, SPST or
DPDT Relays
SERIES WD3 WATER LEAK DETECTOR
Battery or External Powered, SPST or DPDT Relays
The Series WD3 Water Leak Detectors protect equipment from water damage by detecting the presence of
water in drip pans in air handler units, under raised floors in
data centers, or on floors around sump pumps and drains. Water is
detected once it reaches a level that bridges the two conductive
strips on the bottom of the housing. Depending on the model
ordered, audible and visual alerts provide local indication of the
alarm condition and an internal switch will give remote indication
or control to prevent further build up of water.

For applications where power is not available, the Model
WD3-BP-D1-A is battery powered. Otherwise, either AC or DC supply
voltages can be used to power the water detector. The sensing
height can be adjusted to as low as 1/32" using the included
adjustable mounting bracket. The mounting bracket can attach to any
flat surface by either using the attached adhesive strips or
mounting screws.
