ABSTRACT:
Apparatus for the determination of biomass in a suspension and its use in a fermentation apparatus. The apparatus includes electrodes to be placed in the suspension and the following other components: circuit for applying an alternating voltage between the electrodes; circuit for providing a current signal indicative of the current in the current electrode circuit; circuit for providing a voltage signal indicative of the voltage between the ratio between the value of the voltage signal and the value of a quadrature component of the current signal, or vice versa, to provide a capacitance dependent signal.
