GRAVIMASTER
The GRAVIMASTER control system regulates the throughput of an extruder or a dosing screw. It uses gravimetric throughput measurement with the help of a GRAVIFLOW weighing hopper to precisely adjust the throughput of an extruder.
The throughput measurement method is based on the weight loss measurement over a time interval (loss-in-weight). The GRAVIMASTER control supplies the weigh hopper and in turn records the weight signal with little interference, even over a longer distance.
A clear and easy-to-use user interface distinguishes the GRAVIMASTER control. A special feature of this operation is that the extruder can be started via the speed and the gravimetric control can be activated at the operating point. This means that when the system is started, everything is still under manual control. The control has a modern full colour touch display.
