Seojin's Level & Flow Products

There are mercury switch in the sealed glass tube.
When the switch is tilted, contact point outputs at the angle
of 15 tilt

Variations in capacitance between the measuring electrode
in air and the material are transmitted as electrical signals

In this sensor the micro-switch is built in the flange and
permanent magnet is installed in the end of the shaft.
As the float rises or falls with the level of the liquid, the
switch is activated by the magnet

This is designed to adopt radio frequency and measure the
level

This is designed to control the level in container by using
reed switches and magnet.
When reed switches built in inside pipe are contacted by
magnet, contact point outputs and the level is controlled.

This switch is actuated by compression of air column in the
detecting pipe beneath the diaphragm
