Tuffy® II Float switches

Magnetrol International

Switches utilizes float buoyancy for liquid level or interface detection.

Compact sizes allows installation in small vessels or chambers through available threaded or flanged process connections.

Available are models with relay SPDT or DPDT and pneumatic output as well.

The Tuffy® II series achieve switching action through the use of repelling magnets on the float assembly and the switch mechanism. Separating the two magnets with a nonmagnetic barrier. The float follows the liquid level as it changes, causing the attached float magnet to move into the field of the switch magnet. The like poles of these magnets repel each other causing the switch magnet to change position, actuating the switch.

Depending on function available float switches can be divided into following types:

Switches with narrow differential:
T3B - switches for interface detection

T33 - switches with hastelloy C wetted parts, destined for liquid level detection

T31 - threaded or flanged switches with wetted parts made of carbon and/or stainless steel, destined for liquid level detection with minimum density 0,4 kg/dm³

T32 - flanged switches with wetted parts made of carbon and/or stainless steel, destined for liquid level detection with minimum density 0,6 kg/dm³

T35 - threaded or flanged switches with wetted parts made of carbon and/or stainless steel, destined for liquid level detection with minimum density 0,6 kg/dm³

039 - compact threaded switches with electric or pneumatic signal output, destined for liquid level detection with minimum density 0,4 or 0,6 kg/dm³

Switches with wide differential:
T3C - threaded or flanged switches with wetted parts made of carbon and/or stainless steel, destined for liquid level detection with minimum density 0,78 kg/dm³
