Model WD Water Detector from Dwyer Instruments is a dependable indicator of fluid spills, leaks, or small flooding for commercial, residential, or industrial settings. Water sensing tape connects to the switch module and if any conductive liquid comes in contact with the tape, the resistance is changed and the alarm will be triggered. The tape is hydrophobic so it does not absorb any of the liquid it is detecting, which makes for a faster drying time and quicker return to service after a water leak.

Features include DPDT relays for remote indication of water detection, a unit test switch, and continuous tape integrity self check. For versatility, the detector can be powered from either 24 VAC or 24 to 30 VDC. The WD is constructed of robust aluminum enclosure with alarm and power indication LED’s.

Dwyer offers sensing tapes in lengths of 5, 10, 15, and 25 feet and multiple tapes can be easily connected together for additional sensing length. Ideal applications include computer rooms, telecommunication facilities, in drip pans under HVAC equipment, or around pumps.
