INTRODUCTIONO Involves the opening or closing of a

mechanical switch, either through direct

contact with the switch or magneticoperation of a reedO With magnetically actuated float sensors,

switching occurs when a permanentmagnet sealed inside a float rises or fallsto the actuation level.

O With a mechanically actuated float,switching occurs as a result of themovement of a float against a miniature(micro) switch

O For both magnetic and mechanical floatlevel sensors, chemical compatibility,temperature, specific gravity (density),bouyancy, and viscosity affect theselection of the stem and the float

APPLICATIONO AutomotiveToday's automobiles are using safer and smarter electronics in"drive by wire" systems.Electromechanical components such as the Float Switch play avital role in improving these automotive systems and they do sousing little to no power consumption.

Applications such as automotive navigation, entertainment,communication, convenience,.

O Marine and boatMany boat and marine electronics just like automobiles usereed sensor and level sensor products to detect position and/ormonitor liquid levels.

O OthersPower Generators, Oil Pressure Machine, Solar Systems,Boiler, Water Level Controllers and Indicators for OverheadWater Tanks.

O Security & SafetyFire and Safety doors in public buildings, hospitals, governmentbuildings, hotels and other buildings regularly frequented by people,

require the doors to be shut at all times except in an emergency.By law, the doors must be electronically controlled; if they areopened, proper warnings must be given.

O Separation system A special application of float-type sensors is the determination of

interface level in oil-water separation systems.ou can use two floats, with each float sized to match the specificgravity of the oil on one hand and the water on the other.

Another special application of a stem-type float switch is theinstallation of temperature or pressure sensors to create a multi-parameter sensor.

O Appliances Used in appliance such as : Vending Machine, Water Purifier,Humidifier, DishWasher, Coffee Machines and Washing Machine
