Calibration of accelerometer

AccelerometrarRISE is calibrating most types of vibration transducers. The transducer can be calibrated separately or together with its conditioning unit.

The most common type of vibration transducers is the accelerometer, but velocity transducers also occur, especially within the fields of ground vibrations and machine monitoring.

The most common calibration is a sine calibration between 20 and 8000 Hz alternatively between 8 and 3000 Hz.

Low frequency transducers can be calibrated down to below 1 Hz.

Accelerometers which are used at high levels can be shock calibrated up to 50000 m/s².

Velocity transducers can be excited horizontally or vertically.

Reference accelerometers, i.e. calibration standards, are calibrated with laser interferometer technique.

Other types of vibration transducers, e.g. impact hammers, impedance heads and dynamic force transducers, are also calibrated.

Common defects

  • Rough contact surface, caused by e.g. burrs in the surface or a skew mounting adapter, can severely deteriorate the high frequency characteristics.
  • A damaged transducer element can cause a resonance frequency in the measurement range. There is also a risk that the transverse sensitivity has increased considerably.
  • Poor contact in the cable connections often causes trouble in the low frequency range.
