The Murphy Hydrostatic Head Level Switch DF755 is a diaphragm operated “hydrostatic head pressure” level switch. A pressure sensitive diaphragm operates a snap-switch that can be wired directly to electric pilot circuits to control pumps at predetermined levels. Typical application is to start and stop electric driven pump(s) to maintain tank levels. It is also applicable to engine driven pumps. The nitrile sensing diaphragm is impervious to most liquids and is sensitive enough to control levels with 1/4 in. (6 mm) repeatability. Materials include aluminum body, nylon bottom plate and a special alloy leaf snap-switch as standard.

This simple level switch is highly reliable and can be worked into almost any new or existing system without major modification or special tools. The DF755 is suitable for atmospheric tanks in a non-hazardous area. The SPDT snap-switch for the DF755 is preset for a 4 in. (102 mm) differential in liquid level.
