Speed Sensor

Speed sensors are machines used to detect the speed of an object, usually a transport vehicle. They include:

  • Wheel speed sensors
  • Speedometers
  • Pitometer logs
  • Pitot tubes
  • Airspeed indicators
  • Piezo sensors (e.g. in a road surface)
  • LIDAR
  • Doppler radar
  • ANPR (where vehicles are timed over a fixed distance)
  • Laser surface velocimeters for moving surfaces

Famous quotes containing the word speed:

    “Wait, Kate! You skate at such a rate
    You leave behind your skating mate.
    Your splendid speed won’t you abate?
    He’s lagging far behind you, Kate.”
    —David Daiches (b. 1912)
