L072 Series
Side-mounted float level switch with manual reset
The horizontally-mounted L072 is a rugged, hazardous duty level switch equipped with a “push to test” function for monitoring liquid levels. Its all stainless steel construction and ultra-light float provide reliable performance in numerous media and the ability to sense dissimilar fluid interfaces within a 0.1 differential. The L072 is FM-approved for Class I, Div I, Groups A, B, C, D, E, F & G hazardous locations and can withstand pressures up to 1,000 PSIG. Units can be installed for either normally-open or normally-closed operation.
Technology
Float level switches
All float operated liquid level controls operate on the basic buoyancy principle which states "the buoyancy force action on an object is equal to the mass of liquid displaced by the object." As a result, floats ride on the liquid surface partially submerged and move the same distance the liquid level moves. Because of this, they are normally used for narrow level differential applications such as high level alarm or low level alarm.
