Abstract
A processing apparatus, method and recirculation system utilizes a level sensing probe in a filter housing of the filter assembly. The level sensing probe is adapted to provide a signal to a controller arrangement that includes at least a level sensing circuit, a central processing unit and a solid state relay. The controller arrangement is adapted to shut off a heating element of the filter assembly whenever the solution in the filter housing as defined by the level sensing probe falls below an acceptable minimum level of processing solution. With the arrangement of the present invention, it is possible to maintain re-circulated and/or replenished processing solution in the filter housing at an acceptable minimum level, and whenever the solution falls below such a level the heating element is shut off so as to prevent the overheating of the components of the filter assembly.
