Nguyên lý của báo mức kiểu phao từ Finetek FC/FD

The single unit or multiple reed switch units are
housed tightly in stainless steel or engineering
plastic stem, and the permanent magnet is
sealed into the middle of the specified float
ball(s). You can mount the float ball to penetrating
through the stem, then the liquid buoyancy will
deliver the float ball up and down at the specified
position by graduating rings.

When the float internal magnet approaches the
reed switch, it will actuate the reed switch contact
point to create an open or close circuit. We can
apply such on-off output signals to reach liquid
level controlling and monitoring purpose.
The figures below show the float orientations on
N.O. (Normal Open) and N.C. (Normal Close).

Tính năng và đặc điểm của báo mức kiểu phao từ FC/FD Finetek

Multiple points measuring, multiple level points
could be for custom-made.
Employing the magnet to actuate the reed switch
requires no power.
Life expectancy of each contact can reach up to 2
million times.
All output signal wiring are simplified in same
junction box (housing) to economize the external
wiring construction.
FC(D) type magnetic float level switches are more
cost-effective than other level switches in terms of
multiple points.
The housing protection is at least IP65.
Rugged construction and multiple options for
materials from engineering plastics as PVDF,
PP, PVC, and stainless steels such as SUS304,
SUS316, float switches can be applied to
versatile applications in chemical corrosion
of acidity and alkalinity liquid, solvents or oil
fuels.
The reed switch and lead wire are isolated
with liquids absolutely. All stainless steel
switches are applicable to high pressure and
high temperature environment.
