S003 Series TROMBONE float level switches for dirty & viscous liquids
The S003 is a low-cost, single or multiple point level float switch designed for use in extremely contaminated or highly-viscous fluids. Developed for parts cleaners and chemical plating baths, the S003 features a telescoping float arm that slides in and out of the externally-mounted switch tube. The retractable float movement and isolated switch element also make it an ideal choice for thick, slurried or corrosive liquids where conventional float switches will not operate. The S003 is available in lengths extending up to 20″ and can be equipped with three independent switch points. Various wiring options are also available.
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.

The switching action is achieved through the use of a magnetic rod assembly and its interaction with the switch mechanism. As the liquid level fluctuates inside the tank, the float follows and the magnetic rod assembly actuates the switch inside the tube, completing an electrical circuit.
