Model BDK3, BDK10, BDK100

Accelerometer Model BDK

Product features:

  • Very high overload resistance
  • Insensitive to interference by magnetic and electric fields
  • Multiple housing options
  • Light weight
  • Linear frequency response with little or no resonant peak at upper cut-off frequency
  • Low non-linearity
  • Small lower cut-off frequency
  • High signal-to-noise ratio
  • Hermetically sealed
  • Low transverse sensitivity
  • High long-term stability
  • Integrated sensor electronics
  • Low output impedance
  • Long connection lines possible


The dynamic accelerometers BDK3, BDK10, and BDK100 are capacitive spring-mass accelerometers with integrated sensor electronics. Resonant peaks are minimized by dynamic gas damping in the primary transformer. The sensor electronics require only minimal power and are in conjunction with the capacitive primary transformer characterized by low error and high long-term stability.


The accelerometers BDK3, BDK10, and BDK100 are used for applications requiring high overload resistance, high long-term stability, small lower cut-off frequency, light weight and low power consumption. Typical applications include:

  • Measurements on vehicles, machinery, buildings and plants for process control and error diagnosis
  • Seismic measurements
  • Vibration measurements
  • Safety engineering
  • Dynamic measurement of position and velocity
