CALIBRATION

Type 4526 accelerometer is individually calibrated using state-ofthe-art random FFT (Fast Fourier Transform) technology providing an 1600-point, high-resolution calibration (magnitude and phase). This gives a unique characterisation and secures the integrity of the vibration measurement.

Field checking and system calibration are both made simple by using B&K hand-held Vibration Calibrator Type 4294.

 

Supplied calibration values:

  • Sensitivity @ 159.2 Hz
  • Maximum transverse sensitivity verification
  • Amplitude and phase response (5 Hz to 12.8 kHz)
  • Amplitude response with REq-X applied (10 Hz to 12.8 kHz)
