Description

 

Applications

  • 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


Special features

  • 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



Description

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.

The switching functions always refer to a rising liquid level.

The float switch is simple to mount and maintenance-free, so the costs of mounting, commissioning and operation are low.
