Device for measuring the water resistivity in a washing machine.

摘要

A device is described for measuring the water resistivity in a washing machine, in particular a laundry washing machine, comprising a washing chamber; the main characteristic of the device consists in that in contact with the washing liquid two electrodes (A,B) are provided inserted in the charge circuit of a capacitor (Co), and that the measure of the water resistivity is carried out in an indirect manner by way of the measuring of the charge time (Tc) of the capacitor (Co). <IMAGE>
