  • Device for the detection and localization of organic solvent leakages and fabrication process
    Patent number: 5574377
    Abstract: A device for detection of the presence of organic solvents, and a process for the fabrication of the device. This device is particularly useful as a device for the detection and localization of organic solvent leaks, and more particularly to the detection and control of liquid hydrocarbon leaks. In a preferred embodiment the device comprises the combination of a time domain reflectometer and a cable comprised of a composite material constituted of a solvent soluble or swellable thermoplastic matrix containing conductive particles in such a proportion that the whole composite becomes a conductor. Contact with the solvent to be detected causes the matrix to dissolve or swell, which brings about a change in the conductivity of the cable which can be detected by the reflectometer.
