- User friendly and reliable technology proven by the use of many years.
- It is used either for quality inspection of the product being porcessed or as a protection of technology.
- Minimum dimensional requirements (reduction of the range of the area that metal object can occur in) thanks to mesuCAGE technology.
- It conforms to the quality requirements as per HACCP, IFS, BRC and SQF systems.

Metal free zone - MFZ
It is essential for the proper metal detector functioning that there are no fixed (e.g. conveyor structure, its covering) or moving metal parts (e.g. conveyor rollers) in the proximity of the detector’s aperture. Therefore, the MFZ is defined for each detector and it should not contain moving or fixed metals. The aperture of the metal detector is to be placed in the middle of this metal free zone. When you observe the MFZ when installing the detector, you will prevent false alarms and false detections and contribute to the correct detector operation.
Contact us – we will help you with the MFZ calculation for moving and fixed metals.
Sensitivity of a metal detector
The detector's sensitivity depends on many parameters, such as the aperture dimensions (the lower is the aperture height, the higher is the detector sensitivity), the conveyor belt speed, the density of the product, its temperature and humidity, etc.
Maximum obtainable sensitivity can be established by testing your product sample in our laboratory. We will perform these tests free of charge. Please contact us, we will discuss the test execution as well as the dispatch of your material samples.

Metal detectors for textile lines are used to inspect fabrics, fleeces, films and strips of material for metal contaminants — typically broken needles, fragments of machine parts or other metal particles. Detection takes place directly on the moving line without interrupting production.
The Plate metal detector METRON 05 ProfiLine is a single-segment flat detector suitable for standard textile and film lines; it detects the presence of metal across the full width but without precise localisation. The Multi-segment plate metal detector METRON 04 ProfiLine is a multi-segment detector (3–40 segments of 300 mm each) that enables precise localisation of contamination — minimising the amount of rejected material. The Tunnel metal detector METRON 07 CI for lines in textile industry is a tunnel detector integrated into a conveyor belt, designed for faster lines and environments with higher hygiene requirements (HACCP, IFS, BRC, SQF).
The detection width of the flat detectors METRON 05 and METRON 04 ProfiLine ranges from 500 to 12,000 mm (in 100 mm increments). The standard material speed for both METRON 05 and METRON 04 ProfiLine is up to 10 m/s; in the high-speed version of METRON 04 ProfiLine up to 20 m/s, and for the tunnel METRON 07 CI up to 30 m/s.
The METRON 04 ProfiLine divides the detection width into 300 mm segments; when a metal contaminant is detected, the system precisely indicates which segment it is in. This means it is not necessary to reject the full material width — only the affected section is stopped or marked, reducing waste and downtime.
Yes, both METRON 05 and METRON 04 ProfiLine detectors can be installed horizontally or vertically, depending on the configuration of your production line. We recommend a consultation before selecting a model so we can propose the right arrangement for your specific operation.
Flat detectors operate in a temperature range from −10 °C to +50 °C; the high-temperature version of METRON 04 ProfiLine handles up to 120 °C. The tunnel METRON 07 CI has an IP 66 / IP 69 K rating, making it resistant to moisture and high-pressure washing; flat detectors are rated IP 54. All models are designed to withstand vibration and external electrical fields.
We manage the entire project from on-site measurement through custom manufacturing, installation and commissioning to operator training. The AMD 05, AMD 04 and AMD 07 control units allow storage of up to 500 product profiles and connection to higher-level systems; the METRON 07 CI also offers remote access via mesuNET, Ethernet and optionally WiFi. Authorised warranty and post-warranty service is included in the delivery.
