FRINGS has been continuously developing this crucial online sensor since 1986. The basic functional principle is the diffusion of CH components through a semi-permeable membrane. Subsequent adsorption or reaction processes of gas molecules on semiconductor surfaces lead to reversible changes in electrical conductivity.
From this a temperature compensated resistance value is converted into an alcohol value by our automation components type ACETOMAT S7 logic/ ACETOCONTROL S7i logic.
The probe provides a continuous online signal of the current alcohol content in a measuring range of 0.1 – 6% alcohol.
FRINGS Alkosens have already been successfully installed in hundreds of ACETATORS / acetic acid fermenters.
