Metering units
The metering units are equipped with a CANopen bus drive offering the whole range of control-technical advantages of this fieldbus system. All components (incl. metering units) can be managed under a single software surface.
Complex compounding tasks often imply the application of several metering units (volumetric, gravimetric, or combinations). In this case, the rates of the individual metering units need to be interlinked both with each other and with the extruder speed. BRABENDER® offers the corresponding control modules.
