About the KSI84Vx Velocity Sensor

The vibration sensors of the KSI84Vx family are particularly suited for machine condition monitoring to
ISO 20816.
The sensors measure the vibration amplitude within a specified frequency range in axial sensor direction and outputs the measuring result as a 4-20 mA current loop signal. The sensor is supplied with power via the same signal line. The sensor parameters are adjustable. There are different types for different applications in several measuring ranges.

Key Features

  • Suited for direct connection to standard control andm measurement equipment, e.g. PLCs or panel meters
  • Particularly suited for machine condition monitoring to ISO 20816
  • More than 60 typeswith RMS or peak output and different measurement and frequency ranges
  • Loop powered
  • Ground insulated
  • Compact and rugged design
  • M12 socket for easy cable connection
  • Protected against false polarization and overvoltage
  • Double shielded case for best EMC properties
  • Protection grade IP68
