Conductivity sensor for control system Nautilus 2 checks that sufficient quantity of detergent has been dosed during the cleaning process. When detergent is mixed with water, the water's electrical conductivity is changed. The more detergent in the water, the greater the conductivity. This makes it possible to check whether detergent has been added to the water in sufficient quantity by measuring the conductivity.
In the Nautilus 2 the alarm values for the detergents are programmed. If these values are not reached during the cleaning an alarm will come.
