External cage type level switches are completely self-

contained units designed for side mounting to a tank or

vessel with threaded or flanged pipe connections.

In hundreds of industrial applications throughout the

petroleum refining, petro-chemical production and

power generation markets, these switches havethoroughly demonstrated their worth for years.

O P T I O N S

T E C H N O L O G Y

A permanent magnet (1) is attached to a pivoted

switch actuator (2). As the float/ displacer (3) rises

following the liquid level, it raises the attraction sleeve

(4) into the field of the magnet, which then snaps

against the non-magnetic enclosing tube (5), actuating

the switch. The enclosing tube provides a static

pressure boundary between the switch mechanism and

the process. On a falling level, an inconel springretracts the magnet, deactivating the switch.
