Abstract: A sensing system includes a sensor and one or more processors. The sensor includes a sensing region in contact with an industrial fluid. The sensing region includes electrodes and a sensing region circuit electrically connected to the electrodes. The sensing region circuit generates an electrical stimulus having multiple different frequencies that are applied to the industrial fluid via the electrodes. The one or more processors receive one or more electrical signals from the sensor representative of an impedance response of the sensing region to the electrical stimulus. The one or more processors analyze the impedance response and determine at least one of a contaminant concentration of an external contaminant in the industrial fluid, an acid concentration of acidic components in the industrial fluid, or a base concentration of basic components in the industrial fluid based on the impedance response.

Abstract: A system that includes a sensor for measuring a resonant impedance spectral response of an inductor-capacitor-resistor (LCR) resonator and correlating the measured response of one or more spectral parameters to one or more characteristics of the fluid. Such characteristics may be the age or health of the fluid and/or the identification of and concentration of components in the fluid.

Abstract: System includes a sensor operably coupled to a device body. The sensor includes a sensing region and at least one resonant inductor-capacitor-resistor (LCR) circuit. The sensing region is configured to be placed in operational contact with an industrial fluid. The at least one resonant LCR circuit is configured to generate an electrical stimulus that is applied to the industrial fluid via electrodes at the sensing region. The device body includes one or more processors configured to receive an electrical signal from the sensor that is representative of a resonant impedance spectral response of the sensing region in operational contact with the industrial fluid responsive to the electrical stimulus. The one or more processors are further configured to analyze the resonant impedance spectral response and determine both a water concentration in the industrial fluid and an aging level of the industrial fluid based on the resonant impedance spectral response.

Abstract: The subject matter of the present disclosure generally relates to systems and methods for sensing analytes with a high selectivity and low responses to interferences in an environment. In one embodiment, a sensor was developed which comprises a sensor electrode, a coupling element operationally coupled to a discrete segment of the sensor electrode, and an activation material in operational contact with the coupling element and configured to induce an irreversible sensor response for a selected sensing application.
