SFLS300 Side Mounted Float Liquid Level Switch

SFLS300 series side mounted floating ball liquid level switch is based on the liquid buoyancy principle. When the floating ball moves up and down due to the buoyancy, the magnetic spring switch in the junction box is affected by the arm end magnet, and the “no” and “NC” contacts are exchanged. The same principle is applied to the microswitch device. The magnet in front of the microswitch and the magnet at the arm end push the microswitch, resulting in “no” and “NC” actions.

Category

The float level switch also called Liquid Level Switch is operated by magnetic force, without mechanical connection parts, and the operation is simple and reliable. When the float switch is floated by the measured medium, the float drives the main body to move, and the magnet at the other end of the float will control the magnet on the switch action lever.
Technical advantages of float level switch: The float switch does not contain bellows, springs, seals and other components that cause failures. Instead, a straight float is used to drive the internal magnet of the switch, and the simple lever of the float switch makes the switch act instantly. The float cantilever angle limit design prevents the float from being vertical. The float level switch is a simple structure, easy to use, safe and reliable level controller. It is faster than the general mechanical switch and has a long working life; compared with the electronic switch, it has the characteristics of strong resistance to load shock, and one product can realize multi-point control. It has been widely used in shipbuilding, papermaking, printing, generator equipment, petrochemical industry, food industry, water treatment, electrician, dye industry, hydraulic machinery and so on. The float switch is a liquid level control device with simple structure, convenient use, safety and reliability.
