Structural Principles
The magnetic float level switch uses magnetic force to operate, no mechanical connection parts, and the operation is simple and reliable. When the float switch is floated by the measured medium, the float drives the main body to move, and the magnet at the other end of the float will control the magnet on the switch action lever.
In a closed metal or plastic tube, set one or more magnetic reed switches, and then pass the tube through one or more floating balls that are hollow with ring magnets inside, and use a fixed ring to control the floating ball and the magnetic reed. The switch is in the relevant position to make the float float up and down within a certain range. Use the magnet in the float to attract the contacts of the reed switch to generate the opening and closing action.

Application Features
● Can be used for multi-point control. The position of the control switch can be customized according to user needs.
● The use of magnetic reed switch does not require power supply, and the contact life is long.
● All switch outlets are in the same junction box, and the cost of external construction and wiring is low.
● There are PP, PVDF, PVC, SUS304, SUS316L and other materials, regardless of acid and alkali, solvents and various media, there are suitable products for use.
● The reed switch and wires are completely isolated from the liquid, so this product can be used safely in high temperature and high pressure situations.
● Customizable conduit length and switch set point size.

Application
Wastewater/water purification, shipbuilding, generator equipment, petrochemical, food, electronics, dyeing and finishing, chemical, rubber and plastic, hydraulic machinery, chemical and pharmaceutical industries.

Relationship between liquid properties and float

1. The specific gravity of the floating ball is made with water as the reference point. The specific gravity of the liquid is different, and the position of the action point of the floating ball will change. When the specific gravity of the liquid is small, the part of the floating ball immersed in the liquid will be relatively increased. Considering that the specific gravity of the liquid is greater than the specific gravity of the float, otherwise the
   float cannot float and the contacts of the reed switch cannot be converted.
2. There is a magnet inside the float. When there is iron in the liquid, the iron should be filtered first, otherwise it will affect the normal floating of the float and cause abnormal action points.
3. Use larger float balls for viscous liquids (won’t dry), which can prevent the liquid from sticking to the float balls when it rises and falls, causing abnormal action points.
