The part of the weight force of a vehicle (6) flowing over the measuring springs is led over a force sensor (5). A clinometer (12) measures both longitudinal and also transverse inclination of the vehicle (6). The signals of the force sensors (5) and of the clinometer (12) are fed to a computer, which forces the sum of the weight forces that act upon the (here) four force sensors (5). Besides the inclination correction mentioned, the computer performs all the weighing arithmetic operations, such as tare weight formation, weight difference determination, and also calculates transport performance magnitudes. | |
