Overview 

HR-10 Series is a Float Type Level Switch  which is basically operated with the  usage  of 

reed switch and magnet. It can be applied to various storage containers. Also, it can be 

widely used in general industries with high reliability and long life span. 

 

Operating 
Principle 

As liquid level is changed in the tank, the float which is manufactured in accordance with 

the specific gravity of liquid moves upward or downward along the guide pipe with the 

same  liquid  level  by  buoyancy.  The  built-in  magnet  in  the  float  activates  reed  switch 

which is located  in the guide pipe and  contact signal  is out. Each alarm or H/L control 

with multiple setting points is available.
