Float Switch Water Level Sensor

FLOAT SENSOR SWITCH:

The float sensor consists of an electromagnetic switch. It operates just like any other switch. Here, a Magnetic reed switch is placed in the stem of the sensor. A magnet is in the bulb structure of the float sensor. When water fills up in a reservoir, the bulb structure, which has a magnet, starts moving up once the water reaches a certain level. It moves up close to the stem near the reed switch. Due to the force of attraction from this magnet, the reed switch closes, indicating that the water level is high.

When the water level goes down, the bulb moves down, and the reed switch contact breaks. This way, the system detects that the water level has gone down and acts accordingly.

• The maximum switch current of the float is 0.5A and the switch voltage of 100V DC.
• The temperature rating is about 10-85 degrees centigrade.
• The power rating of this sensor is about 10W.
• The entire body of this sensor is made up of plastic
