Continuous Friction Coefficient Tester
Description
TBTCFT-1 is used to measure friction characteristics on road surfaces, airport runways under self-wetted condition, in order to ensure the pavement safety, especially for landing aircraft;
TBTCFT-1 is trailer mounted type which connected with a water spray vehicle to perform the testing.
Machine adopts transducer to measure the load and force, with DMI sensor to record the distance, with temperature sensor to record the pavement surface temperature.
