Vibration Pro
Diffraction Limited Design LLC
Vibration Pro is a true vibration spectrum analyzer using the built in accelerometers and gyroscope inside the iPad, iPod Touch and the iPhone, the built in microphone or the Digiducer series of professional quality external USB accelerometers and USB input sensors ncluding the 333D01, 333D04, 633A01 and 435B39. It acquires and displays time series data, and performs an FFT on each channel to produce frequency spectra. The internal 3-channel accelerometer has a sensitivity of approximately 0.002g and a range of ±7.5g and a frequency range from 0 - 50 Hz (0-3000 rpm) making the iPhone and iPod Touch and iPad sensitive enough to analyze the vibration of most moving machinery. For better sensitivity and a larger frequency range Vibration Pro can be used with external sensors which have sensitivity down to seismic levels and frequency ranges up to 24 kHz.
