CEIA is a manufacturing company specialized in the design, engineering and production of Metal Detectors and Quality Control equipment. CEIA THS 21 Conveyor Inspection Systems satisfy the most stringent requirements for functionality, compact construction, accuracy and reliability of response against accidental metal contamination in food products. The line of CEIA Quality Control equipment includes the Conveyor Inspection Systems, featuring state-of-the-art performance and full compliance with industrial sector regulations. CEIA THS 21 Metal Detectors Series has been designed to manage all the functions required by the transport systems.

CEIA, leading manufacturer of industrial metal detectors, offers a complete range of solutions for inspecting food products, both loose and packaged. The line of Quality Control Detectors includes the Conveyor Inspection Systems, featuring state-of-the-art performance and full compliance with industrial sector regulations.
THS 21 Conveyor Inspection Systems offer total integration between CEIA’s high-performance THS 21 Metal Detector and a hygienic structure in AISI 316L stainless steel, equipped with digital control of the speed and of the stages of ejection of non-conforming products. CEIA’s THS 21 are available in a wide range of sizes covering the different application requirements.
The supporting structure, the Metal Detector and the belt control box are in stainless steel. The inspection system is certified fully compatible with food product handling (FDA compliant) requirements, as is the protective cover of the ejection area and the container for rejected products.

Multi-Spectrum Technology

Exclusively developed by CEIA, this is a unique metal detection technology that both optimizes sensitivity to all metal contaminants and minimizes product effect in a very wide range of possible products.
By recognizing the different frequency response of conductive products and metals, this innovative technology cancels product effect and maintains high performance levels for all types of metal contaminants, both magnetic and non-magnetic.
The autolearn function used by CEIA Multi-Spectrum metal detectors equates to the repetition of hundreds of conventional transits. It explores the whole spectrum of available frequencies in order to determine the best operating conditions resulting in unique detection performance.
