Поплавковый переключатель уровня RSB

Applications

• Mounting on engines, tanks, vessels or enclosures, where, due to a lack of space, installation within them is not possible
• Use for turbulent fluid levels such as in oil sumps in large engines, gearboxes, etc. 
• Pump/level control and monitoring for defined filling levels
• Chemical industry, petrochemical industry, natural gas, offshore, shipbuilding, machine building, power generating equipment, power stations
• Process water and drinking water treatment, food

Special Features

• Freely selectable switch position through fixing the float switch at the required level
• Large scope of application due to the simple, proven functional principle
• For harsh operating conditions, long service life

Description

In a reference vessel (bypass chamber), a float with a permanent magnet moves on a guide tube in relation to the iquid level, following the principle of communicating tubes. 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 switch functions always refer to a rising liquid level: normally open / normally closed / change-over contacts. The float switch is simple to mount and maintenance-free, so the costs of mounting, commissioning and operation are low.
