Electronic level control systems - Bilz series

For machines and instruments that are sensitive to vibration, or where the highest possible positioning accuracy is required, Bilz offers two advanced solutions: EPPC and EPN. Both systems combine intelligent control algorithms with high-quality air springs and provide unrivalled stability, precision and short settling times - with the possibility of remote monitoring and integration into modern automation environments.

Benefits & features

  • High positioning accuracy: Down to ± 10 μm (EPPC™) or ± 0.01 mm (EPN)
  • Automatic adaptation to dynamic load: Shorter equalisation times compared to mechanical-pneumatic systems
  • Intelligent governance: PID control, digital interfaces and web-based configuration
  • Quiet, stable operation: No disturbing magnetic fields or heat generation as with electromechanical systems
  • Combinable with air springs: Support for BiAir® diaphragm air springs and in some cases also FAEBI® rubber springs

 EPPC™ - Real-time control with micron precision

EPPC is Bilz's most advanced level control solution, developed to meet the demands of measuring machines, microscopes and other vibration-sensitive applications.

Key characteristics:

  • Extreme accuracy: ± 10 μm
  • Sensor resolution:
    • Displacement: 0,76 μm
    • Pressure: 0.36 mbar
  • Response time: ~0.4 s for load change (compared to ~0.75 s for MPN systems)
  • Control systems: One servo valve and one displacement sensor per degree of freedom (up to 6)
  • Communication: Ethernet, digital I/O, CAN bus (control up to 20 m from machine)
  • User interface: Web-based, remote access possible
  • Compatible with: BiAir® membrane air springs
  • Typical machine loads: 800 kg - 120 000 kg
  • Natural frequencies:
    • Vertical: 1.2-2.5 Hz
    • Horizontal: 2.2-2.8 Hz

 EPN - Cost-effective intelligence with high precision

EPN is an integrated, electronic level control system that combines compact design, advanced control and easy installation - ideal for modern production where high performance is required at lower cost.

Key characteristics:

  • Positioning accuracy: ± 0,01 mm
  • Control systems: PID control of 3 separate control circuits
  • Valve type: Proportional poppet valve
  • Visualisation: WebVisu - web-based adjustment, diagnostics and remote support
  • Compatibility:
    • BiAir® membrane air springs
    • FAEBI® rubber springs (with additional filter)
  • Features:
    • Pressure monitoring per circuit
    • Automatic safe shutdown in case of power/pressure failure
    • Support for Industry 4.0 integration
