Pressure compensation for high-accuracy feeders
Coperion K-Tron, Niederlenz, Switzerland, has introduced an electronic pressure compensation (EPC) system – believed to be unique – for its loss-in-weight feeders. Main advantages offered by this innovation include 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.
The company points out that 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. They may therefore be over intricate or even unreliable. Coperion K-Tron has now developed 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 the company’s KCM feeder control system. A separate field evaluation kit allows for assessment of potential pressure issues in existing installations. www.coperionktron.com
