Term of the Road Dictionary

bar sensor

  • Language : PIARC Road Dictionary / English
  • Theme : Operations Transport Vehicles
  • Definition : Sensor in the form of a bar containing piezoelectric or piezo-quartz sensor. Note: a bar is generally installed in a groove in the pavement and is smaller than a tyre imprint length. Therefore, if used as a weighing sensor, the signal must be integrated during the time where the tyre applies a pressure on it [COST 323].
