Abstract
Automatic lubrication control system in which current flow between two mating electrically conductive, lubricated members in sliding contact is integrated with respect to time and used to provide a control signal for a pump that applies lubricant to the contact surface. The voltage level resulting from the integrated current flow can be applied directly to control the pump circuit or it can be counted or sampled at preselected times to provide the pump actuating signal.
