METHOD FOR MEASURING THE PRESENCE OF WATER IN GAS OIL FILTERS AND WATER SENSOR FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a method for measuring the presence of water in gas oil filters and a water sensor for carrying out said method, comprising a functional assembly associated with a pair of electrodes (5) that are arranged in the area for decanting water which is separated from the fuel in the gas-oil filters, an electrical current being applied to said electrodes by means of a current source (3) and a switching bridge (4), in measurement cycles separated by periods of electricity, each cycle being determined as a current pulse train, the polarisation of the electrodes (5) being adapted in the first measurement cycle in order to optimise the detection of water in the medium containing same, adjusting the functional activity acting on the duration of the current pulses when the presence of water is detected.
