FIELD: measuring equipment.
SUBSTANCE: invention relates to a device for measuring uniformity of road and aerodrome coatings. Device comprises laser sensor installed on vehicle, which measures distance from sensor to coating, and acceleration sensor fixing vertical accelerations. Said sensors are mounted on solid piston in central through hole made therein. Piston is arranged in cylindrical housing with possibility of free vertical movement on elastic suspension. Cylindrical body has upper and lower covers. Upper cover is made with possibility of connection with car interior by means of air duct. Air duct has an air filter and a branch pipe accommodating a fan for air injection from the passenger compartment into the cylindrical housing. In the lower cover of the cylindrical housing there is a window.
EFFECT: as a result, clogging and fogging of the laser sensor is prevented and accuracy of the obtained results is increased due to reduction of vertical accelerations acting on the sensors.
