Abstract: A locomotive system is provided that includes a platform, plural wheel-axle sets operably coupled to the platform, a reservoir attached to the platform and configured to hold a fluid, and a resonant sensor probe assembly coupled to the reservoir. The sensor probe assembly includes a substrate formed from one or more dielectric materials and free-standing electrodes coupled with the substrate. The free-standing electrodes are configured to be placed into the fluid, to generate an electric field between the free-standing electrodes, and to measure an impedance response of the sensor to the fluid between the electrodes.

Abstract: A monolithic gas-sensing chip assembly for sensing a gas analyte includes a sensing material to detect the gas analyte, a sensing system including a resistor-capacitor electrical circuit, and a heating element. A sensing circuit measures an electrical response of the sensing system to an alternating electrical current applied to the sensing system at (a) one or more different frequencies, or (b) one or more different resistor-capacitor configurations of the system. One or more processors control a low detection range of the system to the gas, a high detection range of the system to the gas, a linearity of a response of the system to the gas, a dynamic range of measurements of the gas by the system, a rejection of interfering gas analytes by the system, a correction for aging or poisoning of the system, or a rejection of ambient interferences that may affect the electrical response of the system.

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: A system includes an impedance gas sensor configured to be in contact with one or more hydrocarbons. The impedance sensor includes electrodes and a sensing region circuit that is configured to have a sensing material and to generate electrical stimuli to the sensing material upon exposure to one or more hydrocarbons at one or more of a reduced heater voltage or a reduced sensing region temperature as compared to a prescribed heater voltage or a prescribed sensing region temperature.

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.
