6. Calibration of speed measuring devices
6.1 Basic principles. Traceability
Tachometric measurements are in the time-frequency domain, where speed n (expressed in rpm) is related to frequency ν (expressed in hertz) by the relationship :
Depending on the equipment to be calibrated, the reference is either a frequency generator or a frequency counter, which must of course be calibrated themselves.
