Sensor element for detection of hydrocarbons |
摘要 |
A sensor for detecting the presence of hydrocarbons and hydrocarbon containing fluids. It is formed of a first conductor which is formed of a metal wire or metal foil covered by an insulative sheath; a second conductor which consists of a hydrocarbon swellable elastomer and one or more conductive fillers; optionally an abuse/abrasion resistant jacket overlaying and preferably surrounding the two conductors and optionally a hydrocarbon permeable overcoat overlaying the jacket. The sensor may be in the form of a continuous length wire or a tape or a sheet. It may be coupled to an electric supply at one portion and a resistance indicator at the return portion. The resistance indicator is then attached to a signaling device such as a light or alarm.
