ISO 20816 machine diagnosis

Rotor turns your iPhone into a working vibration analyser. Hold it against a running motor, pump, fan or gearbox and read the overall velocity in mm/s RMS, graded A to D against ISO 20816, with the machine class cited. Then it tells you what is wrong, and shows you why it thinks so. THE NUMBER IS REAL Acceleration is integrated to velocity in the frequency domain, line by line, with a high-pass cutoff. It is never cumulative-summed in the time domain, which turns sensor bias into a wandering ramp. The graded overall is summed from a rectangular-windowed spectrum so it stays Parseval-exact ins…
