    Float Switches with Permanent Magnet
    For Lateral Mounting
    Model RSB



    Float Switches with Permanent Magnet,
    for lateral mounting, Model 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 and beverage industry


       Special Features
        Freely selectable switch b 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

        Operating limits:
         - Operating temperature: T = -30 ... +300 °C
         - Working pressure: P = vacuum to 6 bar
         - Limit S. G.: ρ ≥ 700 kg/m3

     

       Debion
        In a reference vessel (bypass chamber), a float with a permanent magnet moves on a guide tube in relation to the liquid 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.

     

       Further special features
        Guide tube and float made of stainless steel 1.4571
        Reference vessel made of aluminium AlMg5 or red bronze Rg5
        Universal signal processing: connection direct to a PLC is possible, NAMUR connection, signal amplification / contact protection relays
        Works independently of foaming, conductivity, dielectricity, pressure, vacuum, temperature, steam, condensation, blistering, boiling effects and vibrations
        Maximum 2 change-over contacts
        Exact repeatability of the switch points
        Float switches with permanent magnets qualify as passive electrical equipment in accordance with DIN IEC 60 079-11 and can be installed in 'Zone 1' hazardous areas without certification, so long as the equipment is operated in a certified intrinsically safe circuit with a minimum explosion protection of EEx ib

     

       Options
        Customer-specific solutions
        Reference vessel in another design made of stainless steel 1.4571, with other process connections and with up to 6 switch points
