WebApr 11, 2024 · Analog or digital PLCs trigger the start and end of the data analysis. During drawing time, the sensor output is sampled at a rate of 400 to 800 kHz, depending on the acoustic makeup of the process. The data is then transformed into a spectrogram (time x frequency x amplitude) to better separate noise from chatter signals.
