By using the Order Tracking Program with the RIONOTE Multifunction Measurement System,it becomes possible to record rotation data for a piece of machinery simultaneously with noise and vibration waveform data. The recorded waveform data can then be used offline to perform order tracking analysis for example to assess changes in the sound or vibration state corresponding to a change in rotational speed. The analysis results are shown on the RIONOTE screen as a rotation-level graph. Because analysis is performed offline using the recorded waveform data, parameters such as frequency analysis resolution can be changed later to obtain analysis results for multiple aspects. The concept drawing below shows a system where an accelerometer is placed near a car engine, along with a microphone, rotation sensor, and tachometer to perform measurement.
