  • Leak detector for conductive liquid boiler
    Patent number: 5561418
    Abstract: A leak detector for detecting a leak of an electrically conductive fluid m a vessel comprises an electrically conductive wire having a melting temperature less than an internal temperature of the vessel and greater than the external temperature of the vessel. The wire is stitched to a heat resistant fabric to hold the wire in place and to thermally and electrically insulate the wire when no leaking fluid is present. Detector means electrically connected to the wire outputs an electrical signal if the wire is fused by leaking fluid permeating the fabric.
