ABB Magnetic level gauge switch LMS200

Product Description

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.

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.
