A machine lubrication system that includes an assembly for sensing the level of lubricant in the reservoir, the reservoir including a follower that travels axially within the reservoir and substantially conforms to an inner cross-sectional dimension thereof, a magnet being attached to the follower for actuation of a plurality of magnetically actuated switches. The system may include a first and second level sensor, which may be independently connected to one or more power sources, where the first level sensor may be associated with an operator station, a...


1. A machine lubrication system, comprising: a lubricant reservoir, the reservoir defining a cavity with a longitudinal axis and a cross-sectional dimension perpendicular to the axis;a follower disposed within the reservoir, the follower substantially conforming to the cross-sectional dimension and configured for movement along the axis within the reservoir cavity;a first level sensor comprising a plurality of magnetically actuated switches and resistors that are parts of a sensor circuit disposed within the cavity aligned parallel to the axis; anda magn...
