Abstract: 1405612 Monitoring condition of water softener A J FLECKENSTEIN 13 July 1972 [15 July 1971] 32846/72 Heading G1N In a water softener the need for regeneration of water softening material is sensed by comparing the resistance of a measuring probe 21 in the water softening material to the resistance of a similar standard probe 20 in a closed chamber 14 in the softener tank and containing the same type of water softening material 18. Each probe includes a pair of spaced carbon electrodes 21a, b and 20a, b which are connected in a circuit Fig. 3 (not shown) to provide base bias to respective transistors of a differential amplifier. The chamber 14 is provided with a vent 19 which allows water of the same temperature and of the same relative conductivity as that in the tank to enter chamber 14. If the mineral in chamber 14 is fully depleted then the water and mineral mass provides a conductivity standard. When the resistance measured by the probe 21 becomes greater than that of the standard the respective transistor of the differential amplifier conducts to energize a relay which closes a circuit enabling a switch in a timing circuit which thus, at the appropriate time, causes the regeneration cycle to begin. Instead of using a depleted mineral layer in chamber 14 a properly regenerated material is used, the differential amplifier circuit being arranged to energize the relay at a predetermined level of increase of resistance measured by probe 21 as compared to the standard probe 20. A modified form of probe Figs. 4, 5, 6 (not shown) includes a reference chamber which is connected via an inlet to either the hard water inlet or soft water outlet of the softening tank and which is provided with outlet vents.
