Dwyer Instruments' Series WD3 Water Leak Detector is built to give remote indication to prevent buildup of water
Dwyer Instruments' Series WD3 Water Leak Detector is designed to 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 made to be 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 / or visual alerts are constructed to provide local indication of the alarm condition and an internal switch is built to give remote indication or control to prevent further buildup of water.
For applications where power is not available, the Model WD3-BP-D1-A is made to be battery powered using a coin cell 3V lithium battery. Otherwise, either AC or DC supply voltages are constructed to be used to power the water detector. The sensing height is built to be adjusted to as low as 1/32” using the adjustable mounting bracket.
