Magnetic Float Type Ball Level Switch Long Lifespan For Water Tank
UHK magnetic floating ball and float level switch are made up of
reed pipe and magnetic float. It is based on the buoyancy
principle, using the floating ball with magnetic components to
drive the corresponding position of the reed tube to close or
disconnect, so as to realize the detection and control of the high
and low position of the liquid level. UHK magnetic float and float
liquid level switch are equipped with 8 switches for 8 point
detection. When the magnetic float ball level switch works, it has
no direct contact with the measured medium, no mechanical wear and
tear on the contacts, and it can work without external power
supply.
Features:
1, long life span, stable and reliable operation, easy
installation, almost no maintenance
2, none influence of measured medium in physical and chemical
state. Eg: medium electrical conductivity,
dielectric constants, foam, pressure, temperature, evaporation,
boiling, bubbling effect etc, .
3, choose appropriate material can be used in a variety of bad
media environment with densities ≥ 0.5G/CC ;
4,-interface measurement with two media of different density
control;
5,wide range of application. Pressures from vacuum to PN160
(special up to PN320), temperature -40~+150 ° c;
6,design, explosion-proof, suitable for explosive environments;
7,UHKG controller can be used to control the upper and lower liquid
level.
