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

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.
