(CN214583884-U) NOVELTY - The invention claims an oil seepage sensing film, comprising two conductive layers and an insulating layer located between the two conductive layers, the conductive layer and the insulating layer are coated with a gluing layer; at least one of the gluing layer and the insulating layer is an oil-liquid dissolving material or an oil-liquid swelling material; the conductive layer is fixedly connected with the gluing layer; the conductive layer is formed by at least one conductive belt paved on one surface of the gluing layer; the conductive belt is circuitously paved on the gluing layer; there is a gap between the adjacent conductive belts. The invention is not easy to be influenced by the external environment, low false alarm rate, high sensing sensitivity and high sensing precision effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an induction film. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of oil-permeating sensing method. (Drawing includes non-English language text).
