  • Capacitive sensor comprising a conductive front surface for forming a capacitor plate, and a coaxial cable shielded by a mineral insulator
    Patent number: 5359491
    Abstract: The capacitive sensor comprises a sensor body which includes a housing, a conductive front surface and insulation means provided between the conductive surface and the housing; it also comprises a coaxial cable of the type shielded by a mineral insulator for the connection of the conductive surface to a device for measuring the capacitance of the system formed by the conductive surface, constituting a first capacitor plate, and a reference conductive surface which is arranged opposite to and at a given distance from the first plate and which constitutes a second capacitor plate. The body of the sensor is formed by an electrically open extension of the coaxial cable shielded by a mineral insulator in which the free end of the core constitutes the conductive surface, the extension of the sheath constitutes the housing, and the insulation means consist of a mineral insulator.
