A sensor for detecting leaks of a corrosive liquid is provided comprising a pair of plate electrodes made of a conductive metal which is corroded by the liquid to be detected spaced apart and separated by an inner sheet of an electrically insulating material, the inner sheet having a plurality of through-holes, this entire construction being sealingly encased between a pair of outer insulating sheets, at least one of which has a plurality of through-holes. In use, if a leak occurs the liquid passes through the through-holes in the outer insulating sheet, dissolves a portion of one electrode and passes through the through-holes in the inner sheet to the second electrode, causing a short circuit resulting in a rapid and accurately measurable decrease in the resistance in the circuit and, therefore, detection of the leak.
