General Information
Description
The Murphy LM2000 model maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the
correct running-oil-level, the LM2000 will replenish oil as it is used. An integral, low-level switch will alarm and/or
shutdown the equipment if supply oil is lost and the equipment continues to use oil.
Dimensions
Operating Range of the Snap-Switch
Figure 1 shows the LM2000 dial and the operating
range of the switch. If level is within the designated
zones the switch will activate.
The switch activates approximately 1/4 in. (6 mm) from
the bottom of the low zone. The dial in
Figure 1 shows
that if level continues to drop into the low-low zone, a
shutdown will occur.
