ABSTRACT:
An elongated substantially flat four-conductor moisture detection and location sensor is described. The sensor includes four parallel conductors laminated to a dielectric substrate. Two of the conductors are protected by a water pervious dielectric layer and form the water-sensing element. Two other conductors are covered by a water impervious dielectric layer and are used to loop-back one or more of the water-sensing conductors. Precise location of a water leak location is determined by connecting the four conductors to a resistance bridge. The design allows for the connection of a four-conductor cable to extend the monitoring and detection point to a convenient location without loss of location accuracy.
