The differential pressure sensor VSA 24-D... is a pressure switched controlled by microprocessors with two switching outputs for advance warning (filter contamination high!) and shutdown (maximum contamination reached!). A piston located in the screw-in unit moves across the filter element against the effect of the spring as a result of the increasing pressure drop. The position of the piston, which corresponds to the pressure drop, is transmitted to a sensor in the top.
