摘要： A dielectric constant measurement circuit includes a dielectric constant sensor, an oscillator controlling circuit, a waveform converting circuit, and a counting readout circuit. The oscillator controlling circuit generates an oscillation waveform according to the response of the dielectric constant sensor to a dielectric material. The waveform converting circuit converts the oscillation waveform into frequency division square waves. The counting readout circuit includes a switching counter, a switching circuit, a reference current source, and a current integrator. The reference current source charges the current integrator through the switching circuit controlled by the frequency division square waves, and the switching counter counts the number of the turned-on states of the switching circuit and stops counting the number of the turned-on states when a value of the output voltage from the current integrator reaches a value of the reference voltage, and the number of the turned-on states is related to the oscillation frequency.

摘要： An apparatus for determining at least one dielectric property of a capacitor arrangement, and especially for capacitive examination of a moving elongated test subject such as yarn. It contains an alternating signal generator for applying an electric alternating signal to the capacitor arrangement. The capacitor arrangement is uncoupled from the alternating signal generator by means of an amplifier in such a way that it does not relevantly influence the basic frequency and the signal shape of the applied alternating signal. Detection means detect an electric measuring variable of an electric signal tapped from the capacitor arrangement. The alternating signal generator is set up in such a way that at least one of the basic frequency and the signal shape of the applied alternating signal can be changed.

摘要： A method is disclosed for processing, optimization, calibration, and display of measured dielectrometry signals. A property estimator is coupled by way of instrumentation to an electrode structure and translates sensed electromagnetic responses into estimates of one or more preselected properties or dimensions of the material, such as dielectric permittivity and ohmic conductivity, layer thickness, or other physical properties that affect dielectric properties, or presence of other lossy dielectric or metallic objects. A dielectrometry sensor is disclosed which can be connected in various ways to have different effective penetration depths of electric fields but with all configurations having the same air-gap, fluid gap, or shim lift-off height, thereby greatly improving the performance of the property estimators by decreasing the number of unknowns. The sensor geometry consist of a periodic structure with, at any one time, a single sensing element that provides for multiple wavelength within the same sensor footprint.

摘要： A device for sensing changes in the permittivity of a sample of a monitored medium is disclosed. The monitored medium is exposed to an environment having one or more elements. The device includes an LC oscillator circuit and an output circuit coupled thereto. The LC circuit contains an inductance element and a capacitance element and has a resonance frequency which is dependent upon the permittivity of the sample. The capacitance element includes first and second conductive elements surrounded by an insulating dielectric material so that the first and second conductive elements are prevented from being exposed to one or more elements of the environment of the sample. The output circuit is adapted to output a signal representative of the permittivity of the sample. A method of determining changes in the permittivity of a sample of a medium is also disclosed. The method includes the steps of: (1) disposing a permittivity sensor having an LC oscillator circuit into the medium, the LC oscillator circuit having a resonance frequency dependent upon the permittivity of the sample, wherein the capacitance element includes first and second conductive elements surrounded by an insulating dielectric material, the insulating dielectric material being surrounded by the sample; and, (2) outputting a signal representative of the permittivity of the sample.

摘要： A method for measurement of dielectric constant of a thin film is disclosed which is non-destructive and avoids contact with the film and the substrate carrying it. A first characteristic of the substrate is measured using a capacitance measuring device. Then, the thin film is deposited on the substrate. The first characteristic of the substrate is measured a second time after the film has been deposited. Thereafter, the true film thickness is measured. A ratio of the measurements made with the capacitance measuring device is then established with the actual thickness measurement. The dielectric constant can then be derived from a lookup table or graph calibrated for the tools being used for the measurements.

摘要： Important portions for measurements such as measurement of a peak value can be measured with a substantially constant accuracy, by making an applied sinusoidal wave variable. An amplitude adjuster is disposed behind a sinusoidal wave generator. A sinusoidal wave applied to a voltage electrode is variable. An electrical current induced in a current electrode according to the nature of a sample is fed to an arithmetic portion via a current detector, a peak value-measuring device, and an A/D converter. The arithmetic portion performs a calculation. Then, an amplitude applied to the voltage electrode is determined and adjusted by the amplitude adjuster.
