L001U/L003U Series
Ultra low-level float switches
The miniature L001U/L003U Ultra Low-Level Float Switches offer reliable and economical low-level switching for a wide variety of applications and media. Comprised of polypropylene or polysulfone/buna materials, these compact devices are capable of actuating in levels as low as ⅜”. The switches can be top-mounted with a standard ⅛” NPT or ⅜” – 16 thread mounting (for L001U) and ⅜” – 24 thread mounting (for L003U. An adhesive-backed mounting surface also enables the L001U or L003U to be mounted alternatively at the bottom of a tank. With a larger displacement than other sub-compact models and various material options, the L001U and L003U are suitable for unlimited types of water-based, oil-based, low-density and ultra pure liquid media.
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.
