Float Sensor Plug

Float sensor is basically a reed switch which is used to detect the liquid level. Elint labz has built a plug that has a float sensor with pull down resistor circuit, which provides digital logic levels indicating level of liquid media in which the  sensor is placed. Float sensor switch is available in nylon, polypropylene and polyvinylidene materials so that it can be used with wide range of liquids.

Float sensor contains hermetically (airtight) sealed reed switch in the stem and a permanent magnet in the floating part of the sensor. The reed switch will be in the top portion of the stem. Due to the magnetic field of the permanent magnet, a reed contact is activated, located on the guide tube, after a defined height has been reached.

The float sensor has to be kept inside the liquid medium. When the liquid level is below the float sensor, a LOW signal is available at the Data pin (D) of the float sensor plug and when the liquid raises upto the level of float sensor, float part raises up hence, a HIGH signal is available at the Data pin of the float sensor plug.
