LT small float level switch

Float level switch is a type of liquid level controller that is structurally simple, easy to use, safe and reliable. It has a faster reaction speed, longer working life than general mechanical switches, no complex circuits, and is not affected by interference. One product can achieve multi-point control. As long as the material selection is correct, it can be widely used for liquid level control in various industries such as electronics, power, petrochemicals, water treatment, water supply and drainage, shipbuilding, papermaking, printing, food, dyes, oil pressure, mechanical equipment, etc.

Principle of Action
Install one or more magnetic spring switches as needed in metal or engineering plastic pipes, and then fix a floating ball with built-in magnets inside the main pipe. The floating ball and the magnetic spring switch are in the same position, allowing the floating ball to float up and down within a certain range. Use the magnetism inside the floating ball to trigger the closing or opening of the magnetic spring switch through the main pipe, achieving the purpose of controlling the liquid level.

Application features
Multiple control points can be adjusted according to control requirements, and the control position can be customized according to usage requirements;
The contact adopts a magnetic spring switch (reed switch), and the contact life can reach 2 million times;
There are multiple materials to choose from, including metal (SUS304, 316) and plastic (PFA, PVDF, PP, PVC);
Contact switches do not come into contact with liquids and can be used in high-pressure and high-temperature environments;
Multi point control contacts can be located in the same junction box, which is more cost-effective compared to other switches.

The Relationship between Liquid Characteristics and Floating Balls
1 . The specific gravity of the floating ball is made with water as the reference point. The position of the floating ball action point will vary depending on the specific gravity of the liquid. When the specific gravity of the liquid is small, the part of the floating ball immersed in the liquid will relatively increase. Therefore, when selecting a floating ball, it is necessary to consider that the specific gravity of the liquid should be greater than that of the floating ball, otherwise the floating ball cannot float and the magnetic spring switch contact cannot be switched.
2 . There is a magnet inside the float. When there is iron in the liquid, it is necessary to filter the iron first, otherwise it will affect the normal floating of the float and cause abnormal movement points.
3 . Choosing a larger float for viscous liquids (which will not dry) can prevent the liquid from sticking to the float during ascent and descent, resulting in abnormal movement points.
