Abstract
Apparatus is disclosed for continuously measuring the conductivity of the liquor in a pulp mat on a pulp washer. The apparatus comprises a probe which rests on and squeezes washing liquor from the pulp mat. Two modifications of the probe are disclosed, one fixed and one rotatable. In each case, the probe comprises a pair of electrodes separated from one another by non-conducting material. The electrodes are arranged on the probes to be submerged within the washing liquor squeezed from the mat. The electrodes are connected to an energy source, and when current is applied to one electrode, the current flows through the liquor to the other electrode to complete an electrical circuit. The measurement of the current flow or the resistance to current flow is directly related to the conductivity of the liquor and can be correlated with the soda loss in the pulp washing step.
