Abstract
Continuous on-line monitoring of residual water content in many ″industrial″ fluids has been of great importance in several branches of industry. Typical applications include food and agricultural industries, petroleum and pharmaceutical industries, etc. This contribution presents a novel method for continuous monitoring of the residual water content in non-conductive fluids using an open-ended microwave cavity as a sensor. The principle of operation of a circular open-ended cavity used as a water content sensor, its design, the electronic circuitry for continuous monitoring of the sensor resonant frequency as well as the experimental results for organic oil and powdered whey are presented.
