The platform scale is used to determine the weights of solid materials such as wood-based panels, plasterboard or plastic panels. Measurement can be conducted both at standstill and during running production. The weight is measured by specially developed radial supports with integrated weighing cells. Depending on the measuring task and the mechanical construction of the weighing table, weighing cells with an optimum measuring range are used.
Benefits at a glance
Measurement while production is running or standing still
Can be combined with a thickness gauge to evaluate the raw density
Elimination of incorrect panel weights, continuous monitoring of the material consumption
Improved quality control
Measuring Method
The preferred use of the weighing system during production is to use a belt conveyor that eliminates vibrations with mechanical dampers, suspension arms and electronic filters that are integrated with the evaluation system. The length of the measured material, transport speed, mechanical dynamics, and electronic running times determine the table length and the weighing time of the scale during production.
The electrical signal generated in the load cells is pre-processed by digital weighing electronics and then forwarded to a control console. The weighing data can be sent to a network printer or the data transferred to a process control system. By connecting to a GreCon THICKNESSCONTROL, the average raw density and the weight distribution within the panels can also be calculated and used to optimise the process.
