Oil level switches type FS

Bieri level switches are used to monitor the level and temperature in hydraulic tanks. By means of one or two floats, the maximum and/or minimum medium level can be monitored. In addition, the medium temperature can be monitored.

Features/Design
Safe, potential-free switching
All switching functions are optionally available as NC or NO contacts
The reed contacts are actuated without contact by a ring magnet integrated in the float
The floats reliably fulfil their function even with minor surface damage
Wide range of temperature switches

Design

  • Smallest dimensions
  • Suitable for various liquids
  • The level switch can be installed and removed without removing the tank cap
  • Available in any length and design
  • Fail-safe
  • No supply voltage necessary
  • No penetration of medium into the float thanks to closed pore structure

Applications

  • Presses
  • Inspection and test systems
  • Forming technology
  • Clamping and clamping
