MURPHY L100 / L120 / L127 Float Actuated Oil Level Swichgage For Small Engines and Pumps
L100, L120, L127, L128 – Float actuated oil level Swichgage
浮子液位开关

L100, L120, L127, L128 Float Actuated Oil Level Swichgage instrument


Float Actuated Oil Level Swichgage instruments are a combination oil level sight gage and adjustable, low and/or high limit switch.
浮子驱动式油位开关仪表是一种组合式油位观察计和可调、低限位和/或高限位开关。

限位开关在操作过程中常开,但如果液位下降(或上升)到浮子接触限位螺钉的位置,则限位开关闭合。触点完成电路接地磁电机或跳闸墨菲磁开关。磁性开关可用于激活警报和/或关闭。型号也可不带限位开关。液位计可用于各种曲轴箱、泵齿轮箱或储油器,主要用于小型发动机和泵。安装简单,节省了停机时间和维修成本。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 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.
