초록

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...
