Product Description

Introduction:

B1 Series Water level switch used in water level control field, like the washing machine, dish washer or closestool. it ensures your machine uses the correct amount of water for each wash cycle, preventing overflow and potential damage. 


Model B11 is a kind single water level switch, it can perform as precises as 3mm water level of water, and load with up to 10A currency electronical. Which can drive valve or pump directly.

This type of switch also could come with an overflow terminal, this could prevent the switch failure cause the water overflow problem.


This Switch structured with a thin flexible diaphragm in the center of the housing(like a drumskin),
The diaphragm is separate the sensor housing into two chamber,  one is positive room, and another is negative room. The differential pressure of air will push the sealing part moving, the sealing part drive the switch on and off.
this switch can perform variable of water levels by adjusting a spring pressing oppositely against the diaphragm -

Applications:
Aas water fills into the water tank, air pressure in the air-trap and therefore the switch, increases and the diaphragm distends outwards actuating against a switch which ultimately controls the water inlet valves or pump. 

when the water level falls below a preset level (the differential) a switch may open to enable the machine to stop.
