The LMS200 electric switch is a magnetically actuated double pole
double throw switch. When the LMS200 is mounted on a KM26 magnetic
liquid level indicator, LS series cage level switch or an external
chamber that contains a magnetic float, it can sense high or low
levels within a vessel.
Overview
The LMS200 consists of two snap action switches operated by a
precision actuation mechanism. The actuation mechanism consists of
two cams arranged on a spindle assembly. A rod magnet is internally
mounted to a spindle assembly in such a way as to cause the spindle
to rotate when a magnetic field of proper orientation passes near
the switch. A magnetic KM26 float passing by the LMS200 in either
the upward or downward direction will cause the switch to change
states. After the float has passed, the switch will remain in its
respective state until the float passes the switch going in the
opposite direction. The action of the switch is break before make.
The unique magnetic coupling action eliminates the need for seals,
diaphragms, springs, or torque tubes. There is no physical contact
between the switch and the process. Magnetic coupling also
eliminates the necessity of process connections and insures total
isolation from the process.Data
