Applications

HeavyDuty speed switches from Baumer have been setting the standards for robustness, reliable function and variety of the range for years. They often fulfill the decisive safety function by triggering a switching output when the switching speeds are exceeded or fallen below. In the case of a mechanical centrifugal force switch, the centrifugal force of the centrifugal force at the limit speed moves in a radial direction and actuates the change-over switch. For electronic and digital speed switches, speed-dependent electrical signals are generated and correspondingly internally evaluated for the actuation of up to three switching outputs.

HeavyDuty speed switches and speed monitors support functional safety implementation, for example at

  • Drives
  • Steelworks and rolling mills
  • Cranes and hoists
  • Oil and gas
  • Mining
  • Wind turbines
  • Theater technology
  • Centrifuges
  • Transport and handling systems
  • Automated guided vehicles
  • Dosing and filling stations
  • Cutting installations, punches and presses
  • High-frequency spindles
  • Pharmaceutical installations
  • Saws
  • and any other application where operators are in the danger zone.
