Scientific Technologies, Automation Products Group, introduces the FT-100 Series mechanically actuated narrow-angle float switch in a a high impact, corrosion resistant polypropylene float housing

Scientific Technologies (STI), Automation Products Group, introduces the FT-100 Series mechanically actuated narrow-angle float switch.

Featuring mechanically activated snap action contacts and a high impact, corrosion resistant polypropylene float housing, they are not sensitive to rotation, offer control differential of 1.5 inches above or below horizontal and are designed for high or low level indication.

The FT-100 is intended for pilot duty operation.

It can directly operate an alarm system, such as STI's MP550 Tank Alarm, or it can provide an input to a controller or PLC.

Having passed NSF Standard 61 protocol by an approved Water Quality Association laboratory, the FT-100 Series is ideally suited to operate pumps, valves and similar equipment used in municipal potable water treatment facilities.

They can be used to accurately monitor liquid levels in potable water, water and sewage applications.

For high level monitoring (Type A), 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.

For low level monitoring (Type B), 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.
