<p>LEAKAGE SENSOR An improved capacitive sensing system adapted for use in detecting the presence of a liquid on a floor or the like in which the sensing probe comprises a pair of encased wires held essentially parallel to each other by a plurality of spaced webs which are an extension of casing of take wires, the probe being held flat on the floor over a considerable length so that leakage anywhere along the probe will result in a capacitance change which may be sensed and an appropriate alarm activated in response thereto.</p> |
