Measurement principle

Float ball using magnetic operation, no mechanical connections, simple and reliable operation. When the float ball is measured by the floating float, the float drives the main body and the magnet at the other end of the float moves the magnet switch on the lever.


Technical advantage
The technical advantages of the float ball: float ball does not cause the occurrence of failure and bellows, spring, seal and other components. But the use of straight float drive switch internal magnet, float ball of the simple lever to switch the moment of action. Float cantilever angle limit design to prevent the float from vertical.


Application Guide
The float ball is adapted to control the operation of the pump to maintain the level; control tank automatic loading and unloading; control level or supply signal such as fuel tank, automatic cleaning system, hydraulic tank, low pressure boiler, sewage treatment system.
Small float level switch is a simple structure, easy to use liquid level control parts, it does not have complicated circuit, will not be disturbed,
As long as the material selection is correct, any nature of the liquid, pressure, temperature can be used.
Liquid medium properties and float relationship:
1. When the specific gravity of the liquid is different, the action position of the float will change. In general, the float is immersed in the liquid.
2. Float ball product reference to the proportion of water (SG = 1) so when using the float in the selection of the proportion of the liquid should be considered SG, must be greater than the float specifications,
Otherwise, the float ball can not float.
3. High viscosity will not dry the liquid, the general should use a larger outer diameter float.
4. Float ball is to use the magnet to sense the reed switch, so the measured level should be no iron, otherwise it will affect the action of the float team switch.

Product use
Small float level switch is designed for a variety of small and medium-sized atmospheric pressure and pressure tank level detection, field instructions signal transmission, liquid level alarm, applicable to a variety of health, toxic, corrosive media and explosive Gas Hazardous Locations. There are a variety of installation forms, suitable for all forms of containers.
Product classification
Plastic full PP material non-toxic, food grade, suitable for water media, food, home appliances and other products
PP + NBR float can withstand high temperature, low specific gravity, suitable for oil media
PVDF temperature of 120 degrees, acid and alkali corrosion, compact and durable structure
Teflon products long life, good reliability, more resistant to pressure, for a wide range. Used in most oils, with good stability in water.
Stainless steel all stainless steel long life, high temperature resistance, used in water and oil and weak acid environment
All stainless steel (high temperature) temperature of 200 degrees, suitable for high temperature oil environment
Stainless steel + PP float non-toxic, food grade, suitable for a specific rod length of the water medium products
Stainless steel + NBR float can withstand high temperature, low specific gravity, suitable for a specific length of the oil medium products
Selection: Please follow the test object temperature, pressure, specific gravity, acid and other characteristics, use the table listed in the various specifications of the float.
1, temperature: PVDF maximum temperature of 120 ℃, PP up to 80 ℃, SUS304 / 316 up to 200 ℃.
2, the pressure: plastic float pressure maximum 5kg / cm2, SUS float pressure maximum 30kg / cm2.
3, sticky: should use the ball, the proportion of small float to overcome the liquid surface tension.
4, the nature: plastic material for acid and alkali places, if the temperature should be considered when the choice of PVDF.
5, oily: should use metal material.
6, the proportion: the proportion of float SG must be less than the measured liquid, or floating float float.
7, voltage: 220VAC / 200VDC, current: 0.7A
