® Tuffy liquid level switches are float actuated devices designed for horizontal mounting in a tank or vessel through threaded or flanged pipe connections. The compact size allows for installation in small vessels, while its many features provide a variety of application uses. The single switch mechanism is available in SPDT or DPDT forms on units designed for adjustable, narrow or wide differential and interface service.

Separating the two magnets is a non-magnetic pressure barrier. As the liquid level changes, the float, and therefore the float magnet, moves. The float and switch magnets repel each other causing movement of the switch mechanism, tripping the switch and making or breaking an electrical circuit. Float Magnet Non-magnetic Float holder (pressure boundary) Switch Magnet SELECTION DATA Narrow Differential: Wide Differential: Interface Service: Single Liquid: Adjustable Differential: Narrow Differential Switch differential of approximately 13 mm (0.5") (44 mm (1.72") on interface unit), for actuation of an alarm or system shutdown. Switch differential from approximately 23 mm (0.91") to 127 mm (5.01"), for valve or pump control. Switch to detect the interface between two liquids with SGs that differ by at least 0,1 kg/dm3. Switch to detect the top of layer of a single liquid with no other liquid above it. Wide switch differential from approximately 35 (1.36") to 464 (18.26"), which may be adjusted in the field by repositioning pins on the pivot plate.
