What is the calculation formula of weightlessness scale
Anyone who knows weightless scales knows what the algorithm formulas of weightless scales are. Understanding the algorithm of weightless scales is a necessary skill for professionals. The editor compiled the professional knowledge of this weightless scale algorithm formula and shared it with everyone. Let’s talk about the algorithm formula of the weightless scale. There are two main algorithm formulas for the weightless scale: the calculation formula of the feeding rate of the weightless scale and the calculation formula of the cumulative weight 1. The calculation formula of the feeding rate: the feeding rate of the weightless scale is unit time The internal weight loss value is theoretically expressed as: MTu003ddG/dt where MT: feeding rate dG: weight loss value dt: measurement cycle The feeding rate under the display state of the weighing instrument can be calculated by the following formula: MT u003dn(d±β*d1)/(td±te) where d: the scale displayed by the weighing instrument n: the number of changes in the displayed scale d1: the internal resolution of the weighing instrument-the measurement error coefficient, usually βu003d O.6td: Measurement period te: Timing error coefficient, usually teu003d0.001 2. Cumulative weight calculation formula: In a complete cumulative cycle, the cumulative weight of weightlessness scale discharge consists of two parts, namely, the measurement and storage of the weighing instrument The discharge weight of the weighing hopper and the unmeasured discharge weight during the feeding of the weighing hopper. Gqu003dVA+ VDVAu003d(VH+￡H)-(VL-￡L) VDu003dMTL* tF where VH: upper limit of feed weight in weighing hopper VD: lower limit of feed weight in weighing hopper ￡H : Weight upper limit value weighing error ￡L: weight lower limit value weighing error MTL: feeding rate locked during feeding tF: feeding rate locked at feeding time MTL still changes by K weight display points per second Expressed by the degree value: MTLu003dK(d± β*d1)/(1±te) The feeding time depends on the feeding flow rate MF of the feeding gate, MF≈10 MT tF u003d VA / MF 1 complete accumulation period is ：Teu003dtF+td The average flow rate is: Mqu003dGq/tn continuously accumulate the discharge weight of each cycle, and then the cumulative weight of time tu003d0--tn can be calculated.
