Abstract

PURPOSE: To secure detection for the oil leak with a simple constitution by making use of the phenomenon that the silicone rubber electric conductor swells when it touches the oil thus to increase the electric resistance.
CONSTITUTION: Bar-type pressure-sensitive rubber 5 formed by mixing the carbon or the metal powder into the silicone rubber or silicone rubber electric conductor 5 using the core material containing the cloth or the insulated wire is prepared. Then electrodes 6 and 7 plus lead wires 8 and 8 are provided, and wires 8 and 8 are connected to the comparator (not shown in the diagram) or the PUT. When the oil touches conductor 5, the electric resistance increases between electrodes 6 and 7 to change the output level. Also the metal wire is used for core wire 9, and the synthetic resin 10 is coated around wire 9. Furthermore, the outside of resin 10 is coated with conductor 5. Then electrodes 6 and 7 are attached across conductor 5, and wire 9 and conductor 5 are connected to electrodes 6 and 7 respectively. Thus the sensor can also be formed.
