In the food industry, metal detection is about more than just compliance—it’s vital for consumer safety, brand reputation, and production efficiency. The CEIA THS/21ET multi-frequency metal detector is a comprehensive solution for modern food processing environments. With exceptional sensitivity, automated calibration, and integration into Industry 4.0 systems, it’s helping manufacturers stay ahead of both regulations and operational demands.
Multi-Frequency Detection
The THS/21ET employs multi-frequency technology, allowing it to identify a wide range of metal contaminants—including magnetic metals, non-magnetic metals, and even high-resistivity stainless steels. Its Auto-Learn function automatically selects the most effective frequency during a single product pass, adapting to product variations without requiring manual adjustment.
Whether your production line handles powders, liquids, or packaged goods, the detector maintains precise performance—even at high speeds or in changing environmental conditions—thanks to its wide frequency bandwidth and advanced digital signal processing.
Built to Withstand Demanding Food Environments
Manufactured from AISI 316L stainless steel and food-grade plastics, the THS/21ET is ideal for hygiene-critical environments. It boasts an IP65 protection rating, and full compliance with HACCP, GMP, EU, and FDA standards.
Optional UL and CSA certifications are also available, ensuring the detector meets global food safety requirements. Its robust design makes it well suited for intensive cleaning routines and harsh processing conditions.
Smarter Automation, Less Downtime
The THS/21ET dramatically reduces manual intervention with features such as Auto-Test, Auto-QC™, and real-time self-calibration. These tools help prevent production delays and reduce the likelihood of undetected contamination.
Benefits include:
-
Reduced line stoppages
-
Less product waste
-
Lower labour demands
-
Greater repeatability and consistency
The Auto-QC™ system performs scheduled test sequences automatically, checking calibration accuracy without requiring product ejection—thereby preventing unnecessary waste.
Fully Compliant with FDA 21 CFR Part 11
In a regulatory environment where data traceability is increasingly essential, the THS/21ET is fully compliant with FDA 21 CFR Part 11. The system logs all detections, tests, and configuration changes securely, providing a full audit trail with:
-
Operator logins and electronic signatures
-
Secure data protection
-
Event storage of up to 1,000 entries (expandable to 100,000 with the IXC module)
It’s ideal for manufacturers preparing for audits or working under strict compliance protocols.
Seamless Integration with Industry 4.0
The THS/21ET is more than just a detector—it’s a fully connected smart device. Through the optional IXC module and THS Production 4.0 software, it can integrate with ERP systems such as SAP, Oracle, and Microsoft Dynamics NAV. It also supports OPC-UA, EtherNet/IP, and other industrial protocols for machine-to-machine communication.
Key capabilities include:
-
Real-time data access and monitoring
-
Predictive maintenance tools
-
Centralised control of multiple detectors
-
Web server HMI access and remote diagnostics
-
Report exports in CSV, HTML, or PDF format
Intuitive Design for Easy Operation
Despite its sophisticated internals, the THS/21ET is designed with ease-of-use in mind. A clear, high-contrast OLED display and durable stainless steel keypad provide an operator-friendly interface. Up to 250 product profiles can be stored and quickly accessed.
Maintenance teams also benefit from Bluetooth diagnostics via CEIA’s MD-Scope, allowing remote access for programming and signal monitoring—no opening or cabling required.
