According to wikipedia a float switch is a type of level sensor a device used to detect the level of liquid within a tank. One type of float switch uses a mercury switch inside a hinged float.
Correct Wiring Of Float Switch Into Two Pole Contactor For
How does a float switch work. They used magnetic reed switches that would complete the circuit once the float reaches its lowest point in the water or when the storage tank is empty. Old float switch working principle. A float containing a magnet surrounds the tube and is guided by it. Split into three main parts a typical horizontal float switch consists. Components of a typical horizontal float switch. Another common type is a float that raises a rod to actuate a microswitch.
A float switch works to detect the level of liquid in a tank by using a float magnet and reed switch system that automatically opens and closes when water levels rise and fall inside the tank. Reed float switches are commonly set as either normally open dry or normally closed dry. Established as the standard instrument for industrial level measurement. How does a magnetic float switch work. One pattern uses a reed switch mounted in a tube. New float switch working principle in the past old float switches worked byopening and closing dry contacts to send electrical signals that set off a low water level alarm.
The two leads will be close within the housing but they will not be touching. When the contact between the leaves is made a current can flow via the closed leaves and a switching signal will be detected. Older float switches work by opening and closing circuits dry contacts as water levels rise and fall. Trusted reliability in aggressive environments. As the float on the normally open witches rises with liquid level the magnets pull the blades of the reed switch together completing the circuit allowing power to flow to any attached electronics. Most float switches are the type that just open or close a circuit as the level of liquid in a tank rises or falls.
Float switch can control your water tank level it will make on and off your water tank motor automatically yiu dont need to on the motor and even dont need to off the motor by using this. With the more common reed switch the device will have two electrical contacts sealed in a glass casing. In the case of a float switch with a reed contact with a normally open function on applying a magnetic field the leaves are brought into contact. When the float raises the magnet to the reed switch it closes. Typical float switches are normally resting in the closed position meaning the circuit is incomplete and no electricity is passing through the wires yet.
