BA series Accelerometer

Accelerometers of high overload resistance with integrated 0 to 5V signal conditioner for measurement of acceleration in the frequency range 0 to several 100Hz.

FEATURES:

  • Very high overload resistance
  • Insensitive to interference by magnetic and electric fields
  • Lower limiting frequency is zero; hence suitable for measuring static acceleration such as gravity (inclination) or radial acceleration (centrifugal force)
  • Integrated sensor electronics including normalising amplifier and low pass filter
  • Hermetically sealed
  • High long-term stability
  • Linear frequency response without (BA1) or with only small (BA2, BA3) resonance peak at the high end of the frequency range
  • Excellent signal to noise ratio
  • Small temperature drift
  • Low distortion
  • No measurable hysteresis
  • Small transverse sensitivity
  • 9 to 30V operating voltage, short turn on delay, low current consumption
  • Normalised 0 to 5V voltage output

Description

The Seika BA Series accelerometer of high overload resistance with integrated electronics and normalised voltage output for measuring static and dynamic acceleration in the frequency range 0 to several 100Hz. BA1, BA2 and BA3 are capacitive spring-mass based accelerometers with integrated electronics. The resonant peaks are minimised by gas-dynamic dampening in the primary transformer.
