   Debion
    In addition to the various applications for WIKA‘s float switches for vertical installation, the horizontal WIKA float switches likewise offer innumerable possibilities to monitor and/or switch levels in order to indicate minimum/maximum
levels.
    The float is attached to a supported, swivelling lever and moves with the level of the medium being measured. By means of a permanent magnet, fixed to the other end of the lever, when a preset switch point is reached, a reed contact (inert gas contact) within the contact pipe is energised.

By using a magnet and reed contact the switching operation is non-contact, free from wear and needs no power supply.
The float switch is simple to mount and maintenance-free, so the costs of mounting, commissioning and operation are low.

   Further special features
    ■ Process connection, contact tube and float made of stainless steel 1.4571 or plastic
    ■ 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
    ■ 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
    ■ Process connection, contact tube material and float made of titanium or Hasbloy (other materials on request)
