See Oil Level and Condition Without Shutting Down Shutdown or Alarm on Low Lube Level Adjustable Limit Switch for Alarm and/or Shutdown Save on Reduced Downtime and Repair Costs Simple Installation

The Float Actuated Oil Level Swichgage instruments are a combination oil level sight gage and adjustable, low and/or high limit switch. The limit switches are normally open during operation — yet closed if the level drops (or rises) to where the float contacts the limit screw. The contact completes a circuit to ground a magneto or trip a Murphy magnetic switch. The magnetic switch can be used to activate alarms and/or shut down. Models are also available without limit switches.

The level instruments can be used on a variety of crankcases, pump gearcases or oil reservoirs — primarily on small engines and pumps. Installation is simple, and these instruments save on reduced downtime and repair costs.

The following list displays the model and its typical application:

• L100^†: Small engines and pumps with non-vented crankcase
• L100W^†: Small engines and pumps with vented crankcase
• L120: Machined surface on crankcase such as Witte, National-Oilwell/Garland
• L127: Machined surface on crankcase, specifically, Fairbanks-Morse ZC Series and Bell Engines

† Models available with high and low options.
