Seojin's Level & Flow Products

ST-□S Float type level switches
This is designed to control the level in tank by using reed
switches and magnet.
When reed switches built in inside pipe are contacted by
magnet, contact point outputs and controller can control
motor or valve, and output HH/LL alarms.

SQ Quick float type level Switches
Micro or mercury or reed switch built in inside float is worked
by the movement of float when the head of float is tilted
upward by the buoyancy

SH Sieres Electrode type level Switches
As electrode type, level is sensed by conduction between
measuring material and electrode pole.
When the sensor is conducted the relay unit SEC is actuated
and level is controlled

SMC Sieres Displacement type level Switches
When the measuring material rises and falls the spring built
in housing is proportional to buoyancy of float and outputs
contact points

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

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
