Piezoelectric Sensor Frequency Response Calibration for Folding Boxboard Converting
Piezoelectric sensor frequency response calibration prevents amplitude distortion during high speed creasing by matching amplifier cutoff to rule strike transients.
Iso 16063-22
Calibration Protocol
Methods for verifying the accuracy of shock sensors depend on standardized comparison techniques against a reference instrument. The application of iso 16063-22 ensures that accelerometers used in package drop testing and shipping simulations provide reliable data. It specifies the instrumentation and the mathematical procedures for determining the sensitivity of a transducer under shock excitation.
Technical Requirement
Testing laboratories use a shock machine to generate a high-acceleration pulse that is measured by both the sensor under test and a secondary standard. Adherence to iso 16063-22 requires specific peak acceleration levels and pulse durations to cover the full operating range of the device. The data collected from these pulses helps in calculating the linearity and the repeatability of the sensor across different impact magnitudes.
Engineers use this information to adjust the calibration factors in their data acquisition software. Without this rigorous comparison, the shock values recorded during a container transit test could be inaccurate and lead to faulty packaging designs. The standard also defines the uncertainty budget that must be reported with the results.
Metrological Assurance
Traceability to national standards is maintained through this procedure to allow for global comparison of test results. Certified equipment is necessary for any lab performing compliance testing for international shipping regulations. Verification must occur at regular intervals to account for sensor drift.
