DEVICE FOR DETERMINATION OF ALCOHOL AND SUGAR CONTENT IN WINE Russian patent published in 2011 - IPC G01N33/14 

FIELD: food industry.

SUBSTANCE: proposed is a device containing the first and the second sensor elements accordingly represented by a hollow metal waveguide and a coaxial line section. Inside each of the said sensor elements, on a section along its length, a measurement cell is installed having coordinating dielectric windows on both sides and filled with controllable fluid. The input and output of each sensor element are accordingly connected to the output of the corresponding microwave generator of fixed frequency electromagnetic oscillations (via excitation and oscillation takeoff elements) and one of the inputs of the corresponding power transmission coefficient recording unit the second input whereof is connected to the output of the corresponding microwave generator. The outputs of the power transmission coefficient recording units are accordingly connected to the first and the second inputs of the calculation unit he output whereof is connected to the indicator. The hollow metal waveguide and the coaxial line section are positioned coaxially, the outside surface of the hollow metal waveguide serving as the coaxial line section internal conductor.

EFFECT: increased accuracy of alcohol content determination.
