ABSTRACT:
A sensor cable for detecting the presence of electrically conductive liquids, e.g. water. The cable has decreased sensitivity to contamination and condensation than conventional cables which are covered by braids. First and second elongate conductors are positioned in first and second channels which partially surround the conductor and are part of first and second insulating support members; each channel has at least one shoulder which extends outwardly from the channel beyond the conductor. The channels are positioned so that when the cable is placed on a flat substrate in any position, neither the first nor the second conductor contacts the flat surface and at least one first shoulder and at least one second shoulder make intermittent contact with the flat surface. In a preferred embodiment, the first and second conductors follow a generally spiral path down the length of the cable. When the cable is immersed in an electrically conductive liquid, the liquid provides an electrical connection between the first and second conductors.
