In-line metal detector for pneumatic systems
Ensure product purity and operational efficiency with a solution that effectively removes metal contaminants from pneumatic systems, preventing costly downtime and maintaining high-speed production processes.

Detects and Removes Metal Contaminants
The GF Series from Sesotec is an in-line metal detection system designed for pneumatic conveying lines that specializes in identifying and ejecting metal contaminants from powders and granules. Key features include a unique two-channel detection system that ensures high sensitivity to all metals, including those embedded in materials such as flour, plastic granulate, and breadcrumbs. These systems are suitable for applications in food, plastics, and recycling industries, handling end-products like spaghetti, polyethylene films, and rubber soles. The GF model maintains high throughput without interrupting the material flow, making it ideal for continuous, high-speed operations.
Equipped with quick-lock couplings, it integrates seamlessly into existing vertical, horizontal, or angled piping systems. The equipment incorporates an intelligent auto-learn function to adjust for intrinsic material conductivity variations, and it supports ATEX compliance up to zone 20, ensuring safety in potentially explosive environments. Constructed from stainless steel, it provides robust corrosion resistance and facilitates easy cleaning and maintenance. Furthermore, the units feature a password-protected digital logbook and network connectivity for secure data management, aligning with EU directive compliance for operational security and traceability. Custom configurations and engineering support are available to adapt the system to specific production line requirements.
