Models T5x & T6x Side Mounted Float Switches

Magnetrol® side mounting float switches mount horizontally to any tank or vessel through a threaded or flanged pipe connection. Standard models are normally equipped with a single switch mechanism for high or low level alarm or control applications. Tandem models, with two switch mechanisms, are available for two-stage applications.

Operating Principle

As a counter weighted float follows liquid level change, it moves a magnetic sleeve into or out of the field of a switch-actuating magnet causing switch operation. A non-magnetic barrier tube effectively isolates the switch mechanism from the controlled liquid.
