Electronic compensation for feeders
In a closed feeding system, pressure build-up inside a feeder can significantly impair weighing accuracy. The commonly installed mechanical pressure compensation systems are sensitive to structural factors and machine alignment and may therefore be intricate or even unreliable. Coperion K-Tron has now developed with the Electronic Pressure Compensation (EPC) system a clever but simple electronic solution for accurate and steady pressure compensation in feeder hoppers. The modular design incorporates pressure sensors and electronics tailored to interact smoothly with Coperion K-Tron’s KCM feeder control system.
Depending on set-up and requirements, sensors can be positioned on the feeder hopper and, if required, on the material discharge tube. The software implements a self-optimising compensation algorithm for best performance and dynamics identical to those of Coperion K-Tron’s SFT load cells, which allows for highly accurate feeding results, even in systems with perceivable pressure fluctuations. EPC can be installed on a majority of Coperion K-Tron gravimetric feeders in almost any application and all industries.
