The present invention relates to an apparatus and method for measuring a particulate characteristic of a particulate-containing fluid, in particular for monitoring the particulate content of lubricating or hydraulic fluids in a mechanical system in order to diagnose component failure.

Method and apparatus for isolating a component from a fluid mixture

Method and apparatus for the debris particulate characterization in lubricants

A method and apparatus for generating an impedance spectrum which is characteristic of a sample of bodily matter in a resonant circuit and which may be used to analyse the sample.

Impedance measurements of bodily matter

A method for identifying a change in the composition of a liquid, comprising the steps of applying a time varying electrical or electromagnetic input signal to the liquid in a range of frequencies encompassing a resonant frequency of an electrical circuit comprising the liquid; measuring an impedance quantity of the electrical circuit comprising the liquid by means of the output signal as a function of the frequency of the time varying electrical or resonant frequency input signal in said range of frequencies; determining a resonant frequency of the electrical circuit comprising the liquid; after a change in the composition of the liquid, measuring variation in the impedance quantity at or near to the previously determined resonant frequency of the electrical circuit comprising the liquid; and relating the variation in the impedance quantity at or near to the resonant frequency of the electrical circuit comprising the liquid to a change in the composition of the liquid.

Identifying changes in composition of liquids

There is disclosed a method for interrogating a sensor comprising the steps: applying a periodic electrical signal to the sensor; obtaining a signal therefrom; and performing an operation on the obtained signal to obtain the sensor response at a plurality of frequencies, said operation including a transformation to the frequency domain of said signal or a quantity related to said signal.
