Mini Float Level Switch

FEEJOY resistive level sensor is a sensor with electrical transmission output to remotely indicate liquid, powder, or bulk level. We supply level indicator transmitter types for different applications.

FEEJOY Mini Float Level Switch is a type of float level switch, this series of ultra miniature float switch uses a micro switch for contact output. It is a simple and easy-to-use liquid level control equipment.It is a kind of wireless float switch and waterproof float switch. It doesn't have complicated circuits therefore it can not be disturbed. As long as the material is chosen correctly, any nature of liquid, pressure, and temperature are often used.

Application of Mini Float Level Switch
In the fields of sewage treatment water purification, refrigeration equipment, water coolers, drinking fountains, water boilers, dishwashers, household and commercial electric water heaters, chemical liquids, etc., the liquids in containers such as sealed containers, storage tanks, open containers, and pools are separately carried out, the signal is transmitted remotely, on-site indication, liquid level monitoring, the liquid level is controlled by controlling the start and stop of the pump or the switch of the valve, or the high and low liquid level alarm.

The float is close to or away from the switch point in the rod body under the action of liquid buoyancy. When the float is close to the switch point, the magnetic steel in the float is also close to the dry reed pipe in the rod body. The contacts of the dry reed pipe are closed under the action of the magnetic force. On the contrary, when the float is far away from the switch point, the magnetic steel in the float is also far away from the reed switch in the rod body, and the contacts of the reed switch are disconnected due to the loss of magnetic force.

Normally closed (N.C) when the liquid level rises, the reed switch does not conduct.
