Radio Frequency State Variable Measurement System And Method

摘要

A measurement system and method of conducting cavity resonance and waveguide measurements is disclosed. The cavity or waveguide may be used to monitor the amount, composition, or distribution of a material or sample contained in the cavity or waveguide or passing through the cavity or waveguide. Improved means for operating the measurement system to reduce measurement variability, improve measurement accuracy, and decrease measurement response times are described. The invention's broad applications range from measurements of filters, catalysts, pipe, and ducts where the material collected in or passing through the cavity or waveguide exhibits dielectric properties different from the material which it displaces.

主权项

1. A radio frequency measurement system comprising:
at least one radio frequency probe configured to transmit and receive radio frequency signals through a medium; the medium containing a first material whose dielectric properties varies in a predetermined manner as a function of exposure to at least one second material to the medium; and a control unit configured to determine accumulation of the second material on the medium, based on the received radio frequency signals.
