LR connecting rod float level switch

The connecting rod float level switch is a safe, reliable, easy to use, and structurally simple level controller. One product can achieve multi-point control. Its characteristics are long lifespan, fast speed, and strong resistance to load impact.
The connecting rod float level switch is suitable for controlling the operation of the pump to maintain the liquid level; Automatic loading and unloading of control tanks; Control liquid level or supply signals, such as oil tanks, automatic cleaning systems, hydraulic tanks, low-pressure boilers, and sewage treatment systems.

structural principle
The connecting rod float level switch operates using magnetic force without mechanical connectors, making it simple and reliable to operate. When the float switch is used to float the measured medium, the float drives the main body to move, and at the same time, the magnet on the other end of the float controls the magnet on the switch action rod.
Install one or more magnetic spring switches inside a sealed metal or plastic tube, and then thread the tube through one or more hollow floating balls with circular magnets inside. Use a fixed ring to control the floating balls and magnetic spring switches to move up and down within a certain range. Use the magnet inside the float to attract the contact of the magnetic spring switch, producing the action of opening and closing.

Application features
Can be controlled at multiple points. The position of the control switch can be customized according to the user's needs.
The use of magnetic spring switches does not require power supply and has a long contact life.
All switch outlets are located in the same junction box, making external construction wiring cost-effective.
There are materials such as PP, PVDF, PVC, SUS304, SUS316L, etc., which can be used with suitable products regardless of acidity, alkalinity, solvents, and various media.
The magnetic spring switch and wires are completely isolated from liquids, so this product can be safely used in high temperature and high pressure environments.
● Customizable catheter length and switch set point size

Product Usage
Industries such as wastewater/water treatment, shipbuilding, generator equipment, petrochemicals, food, electronics, dyeing and finishing, chemistry, rubber and plastics, hydraulic machinery, chemical pharmaceuticals, etc.

The Relationship between Liquid Characteristics and Floating Balls
The specific gravity of the float ball is made with water as the reference point. The position of the float ball action point may vary depending on the specific gravity of the liquid. When the specific gravity of the liquid is small, the part of the float ball immersed in the liquid will increase relatively. Therefore, when selecting a float ball, it is necessary to consider that the specific gravity of the liquid should be greater than that of the float ball, otherwise the float ball cannot float and the magnetic spring switch contact cannot be switched.

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.

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.
