روتاری پدل سوئیچ FINETEK مدل SEX20000

The purpose of the rotary paddle level switch is
to detect the presence of solid/powdery material
in most kinds of tanks, bins and containers.
The unit is usually located through a bin wall at
the top, middle or low level of a bin. During
normal operation (no material present) a
synchronous motor rotates the paddle at RPM.
When this paddle rotation is impeded by
material, surrounding the paddle, motor will stall
and cause the Micro-switch to change state
(indicating an alarm or control).
