Need to weigh greatly the problem at chute inclination angle more, such as: coefficient of friction is higher or the material dynamic weighing of thickness, needs to pass through at a high speed
High temperature or the dynamic weighing of cryogenic object, production line high transfer rate require, horizontal direction limited space is dynamic on production line
Weigh.
5, owing to LOAD CELLS designs, Impact direction is vertical with track length direction of weighing (i.e. material traffic direction) pacifies
Dress so that material effective weight G with the frame for movement of chute of weighing invalid deadweight H in the ratio of 1:1 at load cell signal
Middle output, i.e. F=(H+G) cosA.And chute of weighing tilts but F=H+G × cos in sensor levels placement schemes2A+ f×
SinA, G and H press cos2The ratio output of A:1.Visible, this case relative mechanical structure invalid signals, useful signal accounting is bigger,
Requirement to instrument and resolution thereof is lower.
6, this material is weighed the static accurate weight of actual material by Weighing control instrument when weighing landing on chute
The ratio of test result that what control instrument showed weigh as correction factor or the weight of its special calibrating object to this demarcation thing
The ratio of the test result of weighing that Weighing control instrument shows when weighing landing on chute is as correction factor so that inclination
The weight of chute of weighing value of weighing is the most accurate.Inclination angle detection device measuring angle need not be used to be drawn by formula scales again be
Number revises the weight output valve of Weighing control instrument.
7, the feeding chute being arranged at chute feed end of weighing anterior guarantees to exist from the material with production line pay-off
The direction of motion of the discharge end of feeding chute becomes consistent with the length direction of chute of weighing, and is perpendicular to, when eliminating feeding, cunning of weighing
The interference of the impulsive force weighing results of groove, substantially increases weighing precision.
