  • pöördeloendur, pöörlevate masinaosade nurkkiiruse mõõtmise riist
  • an instrument which registers the revolutions per minute of an engine
  • appareil servant à compter le nombre de tours faits par un arbre mobile dans un temps donné
tachometer preferred
Usage examples
  • The engine of a vehicle without a speed governor shall be run at three-quarters of the rpm speed at which, according to the vehicle manufacturer, it develops its maximum power. The rpm speed of the engine shall be measured by means of an independent instrument, e.g. a roller bed and a tachometer.
  • Dangerous overloading of equipment must be prevented at the design stage by means of integrated measurement, regulation and control devices, such as over-current cut-off switches, temperature limiters, differential pressure switches, flowmeters, time-lag relays, overspeed monitors and/or similar types of monitoring devices.
