Abstract
Method for detecting the depletion state of a decalcifying apparatus, of the ion exchange type, characterized in that it is based on the continuous differential measurement between the resistance due to an ion exchange agent, especially a resin, and a standard resistance or other resistance due to the exhausted resin, using an electronic circuit based on operational amplifiers so that a signal is obtained that depends, in practice, only on the difference value of the two resistances mentioned, but not on the variations of voltage or change of the characteristics of the dynamic elements (valves or transistors).
