<h2>Acoustic Emission and Vibrometer Data</h2><p dir="ltr">TDMS files containing the vibrometer and acoustic emission data for the atomiser experiments performed as part of the "Analysis of Sensing Modalities for Electrode-Induction Gas Atomization of Metal Powders" paper.</p><p dir="ltr">The data was recorded at 1.25 MHz. The vibrometer used was a Vibro Go Explorer with one pointed at the upper chamber and one pointed at the lower chamber. The acoustic emission sensors were attached to the upper and lower chambers with torque straps and the signal amplified with a pre-amp. Both sensors were recorded with a PXI system and a custom LABVIEW program.</p><p dir="ltr">The files can be read either in Python with the <a href="https://nptdms.readthedocs.io/en/stable/" rel="noreferrer" target="_blank">nptdms </a>or just with Matlab.</p><p dir="ltr"><b>Note: One of the pre-amps had a dodgy power connector causing the signal during the early runs to drop to 0 Volts occasionally</b></p><h3>TDMS Structure</h3><p dir="ltr">The has one group and several channels beneath it. The group is called VibrationAndAE. It has several metadata properties:</p><ul><li>Datetime: DT stamp for when it was created</li><li>Experiment name: Generated name of the experiment</li><li>Gas Temperature (C) : Gas temperature of the experiment in C</li><li>Gas Pressure (bar) : Gas pressure used in bar</li></ul><p dir="ltr">The channels are named as follows with their own metadata properties generated by LABVIEW as prt of the recording</p><ul><li>Vibro 1: Vibrometer for the upper chamber</li><li>Vibro 2: Vibrometer for the lower chamber</li><li>AE 1: AE for the upper chamber</li><li>AE 2: AE for the lower chamber</li></ul><p dir="ltr"><br></p>
