top float water level sensor supply for industrial

1.Product introduction

LF-20D side-mounted float level switch is characterized by easy use, simple structure, safe and reliable, long working life, small size, fast speed, sturdiness and durability, and the contact life can reach 1 million times. It is widely used in petrochemical industry, generator equipment, food industry, water treatment, electrician and other industries.

2.Working principle

When the floating ball floats up and down under the action of liquid buoyancy, the reed switch (or micro switch) in the junction box interacts with the arm end magnet to cause the reed switch (or micro switch) to act. At the same time, it outputs ON (ON) and OFF (OFF) signals for alarm notification or remote control.

3.Product characteristics

(1) It can be installed horizontally on the side wall of the tank or vertically on the top of the tank;

(2)The structure is simple, the performance is stable and reliable, and the installation is convenient;

(3)The control part is completely isolated from the measured liquid medium and can be used in high temperature and high pressure environments;

(4) Multiple materials and connection methods can meet the needs of different environments;

(5)Wide range of applications: food, medicine, chemical, electronics, shipbuilding, water treatment and other industries;
