Coperion K-Tron has introduced a new Electronic Pressure Compensation (EPC) system for their high-accuracy loss-in-weight feeders. The new system includes improved accuracy and reliability, as well as lower initial cost and easier installation compared to traditional mechanical pressure compensation systems. Retrofitting options for existing feeders are available. EPC can be installed on a majority of Coperion K-Tron gravimetric feeders in almost any application and all industries.
In a closed feeding system, pressure build-up inside a feeder can impair weighing accuracy, but the frequently installed mechanical pressure compensation systems are sensitive to structural factors. Coperion K-Tron has now developed a 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. A separate field evaluation kit allows for the assessment of potential pressure issues in existing installations.
