Modular, electronic pressure compensation for feeders

| By Chemical Engineering

This company has introduced a new Electronic Pressure Compensation (EPC) system for high-accuracy loss-in-weight feeders. Improvements to the system include higher accuracy and reliability when compared with traditional mechanical pressure-compensation systems, which can be sensitive to structural factors and machine alignment, making them potentially more intricate and unreliable. The EPC system’s modular design incorporates pressure sensors and electronics that are tailored to interact with the feeder-control system. Depending on system configuration, the sensors can be positioned on the feeder hopper, and if required, on the material-discharge tube. The integrated software implements a self-optimizing compensation algorithm, which ensures accuracy, even in systems with pressure fluctuations. — Coperion K-Tron, Sewell, N.J.
