Magnetic float level switch FLS

for liquidsfor chemicalsfor the food industry

A float with a permanent magnet moves reliably along with the liquid level on a guide tube. Within the guide tube is fitted a reed contact (inert gas contact), which is energised, through the non-magnetic walls of the float and guide tube, by the approach of the float magnet. By using a magnet and reed contact the switching operation is non-contact, free from wear and needs no power supply. The contacts are potentialfree. Float switches are also available with multiple switch points. Applications of the float switch Level measurement for almost all liquid media Pump and level control and monitoring for distinct filling levels Chemical, petrochemical, natural gas, offshore, shipbuilding, machine building, power generating equipment, power plants Process water and drinking water treatment, food and beverage industry Special features of the float switch Large range of application due to the simple, proven functional principle For harsh operating conditions, long service life Operating limits: - Operating temperature: T = -196 ... +350 °C - Operating pressure: P = Vacuum up to 40 bar - Limit density: ρ ≥300 kg/m3 Wide variety of different electrical connections, process connections and materials Explosion-protected versions
