Product Overview: 

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
  • L128: Machined surface on crankcase, specifically, Arrow and Continental Emsco/Climax

† Models available with high and low options.
