1. Product description
RongSin offers a complete line of standard level sensors and configured models, These products continue to meet the needs of applications in aborad markets, at competitive prices, also RongSin Company offers the capability to design specific liquid level switches for OEM applications that require considerations in materials such as PP, NBR, PVDF, Nylon, SUS304, SS316L, configurations and system interfacing. We have 20 years of experience in liquid level switch applications ina variety of environments and installation configurations. High reliability of the mangentic reed switch assures repeatability at an economical price. Our design experience and flexible manufacturing techniques also offer customers many value added design and sssembly options to reduce their product cost.2. Working principle:

The level sensor is mainly composed of a reed switch and a float, which contains magnetic material, one or more reed switches in a closed non-permeable metal pipe or plastic tube, and then passes the conduit through one or more With a magnetic material of the float, and the use of fixed double-ring control float and reed switch in the relevant position, the float with the liquid rise or fall, the use of the ball near the beginning of the magnetic spring contacts, For level control or indication (when the float is close to the reed switch is turned on; off when the switch is off).3. Operating Principle
Liquid
level
sensors
mainly
consists
of
magnetic
Reed
switch
and
floater
.There
is
a
magnetic
material
in
the
floater
that
will
trigger
the
magnetic
Reed
switch
as
the
level
of
the
liquid
tested
moves
up
and
down
,
and
thus
detecting
the
position
of
the
liquid
level.4. Characteristic
