CEIA THS 21 Metal Detector Series

CEIA Metal Detector Range — THS 21E, MS21 Multi Spectrum & Conveyor Systems

The CEIA metal detector range delivers exceptional contamination detection across food, pharmaceutical, and industrial processing environments. Combining advanced multi-frequency and multi-spectrum technologies, these systems provide unmatched sensitivity to magnetic, non-magnetic, and high-resistivity stainless steel contaminants — even at high line speeds.

THS 21E Multi-Frequency Metal Detector

The THS 21E uses multi-frequency technology to maintain maximum sensitivity across all metal types. An automatic frequency selection function identifies the optimum operating frequency during the autolearn phase, while automatic tracking eliminates variations caused by the product effect. The wide pass band ensures consistent performance at both slow and fast conveyor speeds.

Digital signal analysis from the coil system delivers extremely high sensitivity, strong immunity to interference, and long-term operational stability — making the THS 21E a reliable choice for demanding production environments.

MS21 Multi Spectrum Metal Detector

The MS21 takes detection further by operating across multiple frequencies simultaneously — a significant advantage over conventional multi-frequency detectors that use only one frequency at a time. This multi-spectrum approach delivers sensitivity improvements of up to half the test sample size of a standard detector.

To illustrate: a 4mm test sphere has a volume of 33.52mm³, while a 2mm sphere is just 4.19mm³ — an 800% difference in volume. The MS21's ability to reliably detect at this scale makes it exceptionally effective at identifying small, irregularly shaped contamination that other detectors may miss.

Available for conveyor, gravity, and pharmaceutical applications. All CEIA multi spectrum detectors include a two-year manufacturer's warranty.
