Able to improve Coperion K-Tron loss-in-weight gravimetric feeder operation, Electronic Pressure Compensation (EPC) system promotes accurate and steady pressure compensation in feeder hoppers. Modular design incorporates pressure sensors and electronics tailored to interact smoothly with KCM feeder control system. Software implements self-optimizing compensation algorithm for best performance and dynamics, which allows accurate results even in systems with perceivable pressure fluctuations.
