WEIGHT DETERMINATION METHOD Russian patent published in 1998 - IPC

FIELD: transport facility weight determination. SUBSTANCE: preset number of measurements of primary signals is performed, their results are remembered, multiplied by preliminarily set normalization coefficients, derivative of indication values of the above-indicated signals is calculated, and results are summed up. Pressure sensor signals are used as primary signals. Object weight is determined at moment object is torn off support with due regard for time required for completion of transient processes in measuring system and in object being measured. Moment at which object is torn off support is taken for that when derivative value of pressure sensor signal is close to zero. Derivative value is calculated by averaged values of signals, and graduation characteristics are used as normalization coefficients. EFFECT: enhanced accuracy of weight determination. 3 dwg
