Tachometer Frequently Asked Questions

For example, if you want to set the diameter of the rotating body to 63.66 mm,
DIAMETER 636.6 mm,
Please set the pulse factor (FACTOR) to 1.00000x10E-1 (= 1.00000x10^{- 1}).

The following calculations are performed using the TM-3100.
Peripheral speed (mm/s) = Measurement frequency (Hz) ÷ Number of pulses x Diameter value (mm) x π x Pulse factor
Peripheral speed (m/min) = Measurement frequency (Hz) x 60 ÷ Number of pulses x Diameter value (mm) x 0.001 x π x Pulse factor
