FT-100 Series ­ Mechanically Activated, Narrow Angle Float Switch

Listed 83N2

FT-100 Series - Mechanically Activated, Narrow Angle Float Switch
Listed 83N2
File No. LR54245
point level detection - liquids
The FT series cable suspended floats are designed for high or low level indication. The FT series is a miniature switch actuated design ideally suited to operate pumps, valves and similar equipment used in municipal wastewater treatment facilities. Standard cable lengths are 20 ft. (6 m), and are available up to 30 ft. (9 m). The switch operating levels are easily adjustable by altering the height of the cable fixing point.
Operational Description
FT-100 Series
Mechanically Activated, Narrow Angle Float Switch
This narrow angle sensing device is used to accurately monitor liquid levels in potable water, water and sewage applications. The FT-100 is not sensitive to rotation. Normally Open Model (high level) The control switch turns on (closes) when the float tips slightly above horizontal, signaling a high level. It turns off (opens) when the float drops slightly below horizontal. Normally Closed Model (low level) The control switch turns on (closes) when the float drops slightly below horizontal, signaling a low level. It turns off (opens) when the float tips slightly above horizontal.
Passed NSF Standard 61 protocol by an approved Water Quality Association laboratory Mechanically activated, snap action contacts
Not sensitive to rotation Control differential of 1.5 in. (4 cm) above or below horizontal Three year limited warranty
High impact, corrosion resistant, polypropylene float housing
