Electromagnetic Transducer for In-Line Determination of Alcohol Content in Pisco
Abstract
A specially designed electromagnetic transmission
line is used as an in-line real-time transducer of alcohol content in
pisco beverage production. During the distillation process, as the
beverage is collected in a tank, it is homogenized, and a sample is
continuously pumped into the coaxial line transducer. Pisco is a
beverage with 53%–62% water, and 47%–38% alcohol, with 90%
of the alcohol content being ethanol. The alcohol content of the
flow is detected by measuring the electromagnetic attenuation
of the TEM mode propagating inside the transmission line.
The propagating mode frequency is selected in the 1–1.5 GHz
range, enabling the measurement of alcohol concentration from
0% up to 100%, displaying an almost linear relationship between
the alcohol concentration and power absorption in decibels.
