| 摘要 |
The invention relates to an electronic water detector (10) for hydrocarbon fuel, a kit for such detection and a method for detecting such water safely in explosive atmospheres. The detector comprises a submersible sensor (12), defining a positive and negative electrode arrangement, the sensor (12) being capable of detecting the conductivity differential between bulk hydrocarbon fuel and aqueous liquid contaminants therein; a suitably printed circuit (PC) board; an electronic conductor (13), connecting the sensor (12) and the PC board electronically to each other in a liquid sealed manner; and a suitable electric power source, connected electrically to the PC board to power the board operatively during the use thereof; the PC board and the sensor (12) characterised in being coupled to provide a negative submersible electrode only, with the negative and positive electrode arrangement being located remotely from the submersible sensor (12) and remotely from the hydrocarbon fuel, so as to negate the risk of spark ignition of the fuel. |
