This study presented a calibration method for very low frequency IEPE accelerometers and demonstrated using wind energy structure as a sample case. The presentation is detailed with convincing results. One piece needing more discussion is IEPE simulator, and its design, parameter determination, and potential impacts on the overall calibration approach will be interesting to the audience. However, the approach appears needing a lot of customization and hard to have huge impact on wind or sensing industry. On the other hand, the contents appear more appropriate to be released through a publication venue with more sensing elements than wind.

Paper is well structured and well written.

In introduction section please extend the literature review about the sensors used today in the wind industry sector

Fig. 13: please elaborate more on the physics or reasons behind the differences seen in this figure

It would be nice if the authors can provide a table in section 6 providing suggestions for selecting suitable sensors for different range of frequencies in different wind turbine components

Short summary

This work presents a method to use low-noise IEPE sensors in the low-frequency range down to 0.05 Hz. In order to achieve phase and amplitude accuracy with this type of sensor in the low-frequency range, a new calibration procedure for this frequency range was developed. The calibration enables the use of the low-noise IEPE sensors for large structures, such as wind turbines. The calibrated sensors can be used for wind turbine monitoring, such as fatigue monitoring.
