Abstract: A method for determining residual coupling of an inductive, conductivity sensor, in which the conductivity sensor is surrounded by a measured medium and an equivalent impedance of the medium is calibrated with a variable compensation impedance. The variable compensation impedance and the equivalent impedance of the medium act on a measuring coil of the conductivity sensor with a phase shift of 180°. In order to be able to perform a measuring of the residual coupling with a high accuracy of measurement at any time during operation of the conductivity sensor, the variable compensation impedance is varied until an output voltage of the measuring coil of the conductivity sensor assumes a minimum voltage; wherein the minimum voltage corresponds to the residual coupling of the inductive, conductivity sensor.

Abstract: The invention refers to a chamber for measurements of electrical properties of reactive powder or liquid samples, allowing the measurement of various electrical parameters to be carried out. The present invention provides the chamber in two variants of embodiment: the multiple use chamber and the single use chamber. The construction of the chamber provides the possibility of carrying out the measurements with the sample placed directly between parallel active surfaces of the electrodes placed coaxially and sliding in a precise manner in to a thin-walled cylinder made of insulating material providing electric insulation. Elements remaining in contact with the sample are made of chemically inert materials. Additionally, a module containing a pair of the electrodes and the cylinder made of insulating material is detachable from the rest of device elements, that enables its loading and hermetic closure in a glovebox filled with inert gas. The device provides the possibility of carrying out the electrochemical measurements as a function of temperature and pressure. The present invention also refers to a method of carrying out measurements of electrical properties of reactive powder or fluid samples, wherein a sample is loaded into a measurement chamber in an inert gas atmosphere, then the gaseous phase is removed from spaces between parallel active surfaces of electrodes and additionally, solid samples are subjected to compression, and then in the system of regulated temperature and/or pressure a measurement of a selected electrical parameter as a function of time and/or temperature and/or pressure is carried out.

Abstract: An exemplary method for measuring the electrical resistance and/or electrical conductivity of solutions, includes: exciting the electrodes with a rectangular shaped, alternating current of a certain frequency fH through a connecting cable; synchronously rectifying a voltage of the electrodes of the measuring cell in response to the alternating current, calculating a first average voltage, dividing the first average voltage by the current amplitude to obtain a first impedance RH; then exciting the electrodes with a rectangular shaped, alternating current of another frequency fL through the connecting cable; synchronously rectifying the voltage of the electrodes in response to the alternating current, calculating a second average voltage, and dividing the second average voltage by the current amplitude to obtain a second impedance RL. Based on a mathematical model, a relation between the resistance R between the electrodes to be measured and the first and second impedances RH and RL, and the ratio n of the frequency fH to fL is established, so as to derive the resistance R between the electrodes. The conductivity of the solution can be derived by incorporating an electrode constant.

Abstract: According to typical inventive practice, the relative positioning of two press members is mechanically adjustable so that their respective flat surfaces remain parallel at selectively closer or further distances apart. During immersion or partial immersion of the two press members in a fluid of interest, a fluid sample is bounded by the two opposing flat surfaces. The present invention can thus achieve small thicknesses of its fluid samples, which represent “thin fluid films” suitable for measurement of one or more electrical characteristics (e.g., impedance, or impedance-related characteristics such as permittivity). Data acquisition can be performed by generating electrical pulses and receiving data signals from probes contiguous with the fluid sample. Measurements can be taken of fluid samples characterized by varying thicknesses and/or varying pressures. As distinguished from conventional methodologies, which are beset with “bubble-bursting” transience and fragility, the inventive methodology provides thin fluid films that are stable and robust.

Abstract: A system and related method are provided to calibrate for wire capacitance during use to minimize error in conductivity measurement of the target fluid. The system includes a signal generator configured to drive the conductivity cell and the temperature element, with an alternative current (AC) drive signal having variable parameter. The system further includes a processor assembly electrically coupled to the conductivity cell and the temperature element to calculate a conductivity value of the fluid. The conductivity value is a function of the values of the temperature measurement, the compensation measurement, and the raw conductivity measurement, thereby compensating the conductivity value for capacitance effects. In this manner, the system effectively compensates for capacitance attributable to wiring extending between the electrode and other electronics of the sensor, usable with wiring of varied and unknown lengths.
