What's the difference between odometer and tachometer?

Odometer


Definition:

  • (n.) An instrument attached to the wheel of a vehicle, to measure the distance traversed; also, a wheel used by surveyors, which registers the miles and rods traversed.

Example Sentences:

  • (1) A cart equipped with an odometer, for measuring distance, and a hydraulic dynamometer, for measuring draught force, was used.
  • (2) A wagon equipped with an odometer and a hydraulic dynamometer was used for measuring distance and draught force.
  • (3) Voluntary exercise was provided by free access to running wheels fitted with odometers.
  • (4) The hydrostatic pressure required to reduce the water content of rabbit feces in an odometer from greater than 80 to less than 65% was approximately 5 atm.

Tachometer


Definition:

  • (n.) An instrument for measuring the velocity, or indicating changes in the velocity, of a moving body or substance.
  • (n.) An instrument for measuring the velocity of running water in a river or canal, consisting of a wheel with inclined vanes, which is turned by the current. The rotations of the wheel are recorded by clockwork.
  • (n.) An instrument for showing at any moment the speed of a revolving shaft, consisting of a delicate revolving conical pendulum which is driven by the shaft, and the action of which by change of speed moves a pointer which indicates the speed on a graduated dial.
  • (n.) An instrument for measuring the velocity of the blood; a haematachometer.

Example Sentences:

  • (1) Speed settings were recorded as percentages of the servomechanism's maximum tachometer feedback voltage (10 to 100% Vfb max).
  • (2) Speed settings were standardized percentages of each machine's maximum tachometer feedback voltage (0 to 100% Vfb max).
  • (3) Displays of a tachometer and a special timing device are large enough to be clearly visible on the film.
  • (4) A Grass polygraph and tachometer were used to record the applied pulses and nodal firing rates; simultaneous magnetic tape recordings were obtained and used for data analysis.
  • (5) This report describes a safe and inexpensive method of modifying a centrifuge lid so that calibration of the machine with a photoelectric tachometer is a simple and safe procedure.
