ABSTRACT:
In a humidifier, an evaporator has a vessel containing two or more spaced vertical electrodes across which a voltage can be applied. The current which flows depends on the cross-section of the immersed portion of the electrodes, the size, shape and spacing of the electrodes, the applied voltage and conductivity and volume of the water. The invention provides a probe for measuring the conductivity of the water in the vessel and replacing some of the water in the vessel with fresh water when necessary to reduce the conductivity to the value for which the evaporator is designed. The probe may be connected directly into the evaporator or it may be connected to a voltage source so that a current dependent on the water conductivity will flow between these electrodes. This current can be compared in a comparator with a reference value and, if the reference value is exceeded, an RC timing circuit causes energization of an outlet solenoid valve for a time dependent directly on the extent to which the measured conductivity exceeds the reference. A timer causes the probe to measure the conductivity at preset intervals.
