Abstract:
A sensor includes a resonant transducer, the resonant transducer being configured to determine the composition of an emulsion. The composition of the emulsion is determined by measuring the complex impedance spectrum values of the mixture of the emulsion and applying multivariate data analysis to the values.
Abstract:
Systems and methods are provided for environment sensing. The system includes a sensor node having a sensor. The sensor includes a sensing material configured to be in contact with an ambient environment. The system includes a remote system having a communication circuit and a controller circuit. The communication circuit is configured to be wirelessly communicatively coupled to the sensor node. The controller circuit electrically coupled to the communication circuit. The controller circuit configured to receive an impedance response of the sensing material and analyze the impedance response of the sensing material at frequencies that provide a linear response of the sensing material to an analyte of interest and at least partially reject effects of interferences.
Abstract:
This disclosure describes a sensor comprising a single- or multi- resonant transducer (12, 31) to determine the composition or concentration, or both, of one or more components of an emulsion or dispersion. In some examples, the sensor is used to measure the type or concentration, or both, of clay in water or in a mixture of oil and water.
Abstract:
A system includes a vessel system for a fluid, a sampling assembly and a resonant sensor system coupled to the sampling assembly. The resonant sensor system may include a subsystem that detects a set of signals from a resonant sensor system at a plurality of locations in the vessel. The resonant sensor system may also include a subsystem that converts the set of signals to values of a complex impedance spectrum for the plurality of locations and stores the values of the complex impedance spectrum and frequency values. A subsystem determines a fluid phase inversion point from the values of the complex impedance spectrum.
Abstract:
A microwave emitter (206) for use in a microwave sensor assembly (110) that includes an emitter body (300) includes a first arm (310) that extends radially outward from the emitter body. The first arm is at least partially non-linear and includes at least one peak (334) and at least one trough (336). The microwave emitter also includes a second arm (312) that extends radially outward from the emitter body. The second arm includes at least one peak and at least one trough. The first arm and the second arm generate an electromagnetic field when at least one microwave signal is received.
