In an external chamber (bypass chamber), a float with a permanent magnet moves on a guide tube in relation to the liquid level, following the principle of communicating vessels. 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 potential-free.
• Freely selectable switch position through fixing the float switch at the required level
• Large range of application due to the simple, proven functional principle
• For harsh operating conditions, long service life
• Operating limits:
- Operating temperature: T = -30 ... +300 °C
- Operating pressure: P = Vacuum to 6 bar
- Limit density: ρ ≥ 700 kg/m3
• Mounting on engines, tanks, vessels or enclosures, where, due to a lack of space, installation within them is not possible
• Use for turbulent liquid levels such as in oil sumps in large engines, gearboxes etc.
• Pump and level control and monitoring of distinct filling levels
• Chemical, petrochemical, natural gas, offshore, shipbuilding, machine building, power generating equipment, power plants
• Process water and drinking water treatment
