Float Switches

A float switch is a level sensor used to detect the level of liquid usually in a tank, container or well. The flotation part of the device sits on top of the liquid and will switch on the rise and fall of the liquid. Float switches are used for automatic level control of groundwater, wastewater and sewage pumps, for raw water and liquid transfer pumps at waterworks, and for high water alarm.RS Components offer a wide range of high-quality horizontal and vertical devices from leading brands including Cynergy3, Pepperl + Fuchs, Gems Sensors, Telemecanique and of course RS PRO

What does a float switch consist of?

Float switches have a reed switch and a pivoted magnet and can be used for normally open (N/O) or normally closed (N/C) operation. The switch action can be reversed rotating the switch through 180°. The movement of the float, due to changing fluid level, will cause the reed change to work (for instance close or open) at a specific level. This trusted and tried technology depends on a generally straightforward plan that offers long-haul quality without the requirement for the user to calibrate a switch.

What are material types of a float switch?

Nylon – used for oils, diesel, organic chemicals.Polypropylene (PP) – acids and alkali, detergents, oils, water, organic chemicals.Polyphenylene sulphide (PPS) – used for more aggressive chemicals, and higher temperatures, up to 120ºC.Stainless steel – medical and food industries, hydraulic fluids, chemicals.

Features and Benefits

The highly flexible thermoplastic rubber cable has an extremely high mechanical load rating.The drop shape of the stabilizing weight eccentrically mounted in the housing makes the float switch insensitive to turbulence.The microswitch, fitted in a dual-chamber system, is completely shock- and rupture-proofAvailable with WRAS approvals.

What applications can be float switches used?

When emptying a tankWhen filling a tankFor alarm at high water levelFor alarm at low water level
