VEHICLE WEIGHT DETECTOR Russian patent published in 2014 - IPC G01G19/03 

FIELD: measurement equipment.

SUBSTANCE: proposed invention relates to measurement equipment, namely, to vehicle weight detectors. The proposed vehicle weight detector designed for laying into a road surface of a highway at an angle to its axial line, comprises at least one linear sensitive elements and upper and lower linings, between which there are linear sensitive elements fixed, having practically one and the same cross section in the vertical direction, besides, the material of each lining is the material, the coefficient of linear thermal expansion of which is close to the coefficient of linear thermal expansion of the material, forming the layer of the road surface, in which the sensor must be laid.

EFFECT: due to the proposed invention, such technical result is achieved as the provision of reliable fixation of the sensitive element position strictly along the sensor axis with the preservation of mechanical integrity of the sensor and an adjacent layer of the road surface.
