Model B

Accelerometers of High Overload Resistance with Integrated Electronics for Measurement of Acceleration

Acceleration in the frequency range 0 to several 100 Hz.

Products Accelerometers Model B1, B2, B3

Model B1, B2, B3

Accelerometer Model B

Product features:

  • Very high overload resistance
  • Insensitive to interference by magnetic and electric fields
  • Lower cut-off frequency is zero, hence suitable for measuring static acceleration, such as gravity (inclinations) or radial acceleration (centrifugal force)
  • Linear frequency response with little or no resonant peak at upper cut-off frequency
  • Low non-linearity
  • High signal-to-noise ratio
  • No measurable hysteresis of signal
  • Hermetically sealed
  • High long-term stability
  • small temperature drift
  • Integrated sensor electronics
  • Analog DC or pulse width modulated or frequency modulated output
  • Low power consumption
  • Very short on-transition delay
  • Multiple housing options

Description

The sensors B1, B2 and B3 are capacitive spring-mass accelerometers with integrated electronics. Resonant peaks are minimized by special gas-dynamic damping in the primary transformer.The sensors are manufactured with an analog DC output. The sensor electronics require only small amounts of power and are in conjunction with the capacitive primary transformer characterized by low error and high long-term stability.


Application

The accelerometers B1, B2 and B3 are used for applications requiring high overload tolerance, high long-term stability, small lower cut-off frequency down to measurement of static acceleration, very short on-transition delay and low power consumption. Typical applications include:

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