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 industry, 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 ... +150 °C
  - Operating pressure: P = Vacuum up to 40 bar
  - Limit density: ρ ≥600 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.
