B02B04 – IEPE Calibration Reference Accelerometer

Any type of sensor must undergo a comprehensive and rigorous performance evaluation according to design specifications after assembly. After a period of use or repair, a calibration test must also be conducted for the main technical parameters to ensure that all performance indicators meet the required standards.

To further enable comparative calibration with other accelerometers, LNS has introduced a B02B04 IEPE reference standard accelerometer.

Product Features

  • Dual-head M5/10-32 back-to-back calibration, designed as a reference standard sensor.
  • High-reliability structural design.
  • Excellent frequency response characteristics.
  • Special piezoelectric material with high long-term stability and low transverse sensitivity.
