Abstract | Measurement of the impedance and complex resistivity of a sample is used for measuring parameters resulting from a change in physical or chemical state. A variable frequency signal is provided by a transformer primary coil. A secondary coil of the transformer with a closed loop and electrically coupled said sample is monitored along with a leakage current sensor. Sampling at multiple signal frequencies is performed at the multiple signal frequencies. |
