Device for measuring permittivity of materials

摘要: A device for measuring permittivity of materials on the basis at least two different capacitance values a capacitor connected to material being tested and oscillator output which is coupled one input mixer whose other reference through frequency meter resetting unit, characterized in that has main electrodes permanently oscillator, additional electrode alternately by switch course measurement, while said unit pulse counter actuated synchronously with so position this above, switch, below oscillator.
