This liquid level sensor combines a floating ball with a spring switch array inside a sealed nonmagnetic tube to provide precise level measurement in demanding conditions. Key benefits Precise level detection across wide liquids, pressures, and temperatures when material selection matches the liquid Robust, corrosion resistant construction with a sealed nonmagnetic housing for harsh environments Easy installation and low maintenance with a modular design for quick replacement or adjustment Working principle The float rises and falls with the liquid level. A magnet in the float actuates multiple spring switches inside the sealed tube, producing a reliable electrical signal corresponding to the level Materials and compatibility Suitable for a wide range of liquids when the material selection is appropriate Typical configurations use stainless steel or other nonmagnetic housing and compatible seals Applications Marine shipbuilding and ballast or fuel tank monitoring Petrochemical process vessels and storage tanks Water treatment and food processing lines
