2、 Instruction

LS50 Liquid Level Switch uses a floating ball as the sensing element. When

the floating ball is in the liquid, it changes with the liquid level buoyancy.

With the liquid level rises and falls, the contact moves up and down;Install

a permanent magnet on the switch mechanism. When the float rises with

the liquid level, the contact enters the magnetic field of the magnet, and

then the magnet closes the c ontact quickly to make the switch act.When

the liquid level drops, the reset spring causes the magnet to retract, thereby

releasing the action of the switch mechanism and realizing the automatic

control process of the liquid level.

3、Order Goods  

◆ Please tell us the model and nominal diameter size of interface you want

when ordering.

◆ Example:LS50-20 it is means DN20 interface Liquid Level Switch, if the

interface diameter is not specified, it will be defaulted is 25.
