Water Leak Detectors

“WBThe WB Series is a small, lightweight device that activates and illuminates when water is sensed. Simply place on any flat surface under your equipment or attach using the included mounting brackets. The WB relies on the electrical conductivity of water to change the resistance across two contacts at the base of the enclosure. When the contacts are bridged by water, the resistance changes and triggers an alarm.

Choose the WB for applications that require visual alert and/or relay contacts. The WBWO-1 provides a visual alarm and the WBWA-1 unit will trigger both visual and audible alarms when water is sensed. Both units require an external 24VAC/VDC power supply.
