FIELD: physics.
SUBSTANCE: method consists in measurement of weight force with force-measuring sensors, and linear accelerations of load-receiving device are measured with accelerometers that are installed with their sensitivity axes along sensitivity axes of force-measuring sensors. Both signals are synchronously transformed into digital form and then filtered with the help of two filters inbuilt in device, with consideration of number of noisy low-order digits of every of applied analog-digital transducers. At the same time the first filtered signal is divided by the second filtered signal to obtain actual value of weight mass without dynamic errors with higher accuracy. Received mass value is multiplied by terrestrial acceleration due to gravity inherent in this place of the globe and load weight is determined.
EFFECT: improvement of weighing accuracy.
