Magnetic Float Switch - HLS

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
In addition to the various applications for float switches for vertical installation (model FLS), the model HLS horizontal 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 end of the lever, when a preset switch point is reached, a reed contact (inert gas contact) within the contact tube is actuated.
Features
  • Large scope of application due to the simple, proven functional principleStainless steel and plastic versions.
  • Large scope of application due to the simple, proven functional principle.
  • For harsh operating conditions, long service life.
  • Operating limits:.
    • Operating temperature: T = -196 ... +350 °C.
    • Working pressure: P = vacuum to 232 bar.
    • Limit S. G.: ρ ≥ 600 kg/m.
  • Stainless steel and plastic versions.
  • Explosion-protected versions.
