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:

    “Spig Wead: I’ve been thinking what a heel I’ve been about you and about my own kids. I don’t know, when I do something, I go all the way. Living. Gambling. Flying. I tap myself out. I guess that’s the way I want it to be. Maybe even the way I am.
    Minne Wead: Star-spangled Spig. Damn the martinis, full speed ahead and don’t give up the ship.”
    —Frank Fenton, William Wister Haines, co-scenarist, and John Ford. Spig Wead (John Wayne)
