Tunnel metal detector METRON 07 CI for lines in textile industry
The METRON 07 CI tunnel metal detector with integrated control unit tunnel metal detector is used to detect metal particles in products transported on the conveyor belts. The imagePHASE system enables product visualization on the control unit display.
The space requirements for the installation of the METRON 07 CI metal detector are minimal – thanks to the mesuCAGE technology, a needed metal-free area has been significantly reduced.
It is a synonym for metal detectors with high detection accuracy and reliability.This detector is fitted with a top-class AMD 07 control unit with a range of advanced functions. Its operation is simple and intuitive thanks to the touch screen
The METRON 07 CI metal detector enables the metal detection in materials transported on a conveyor belt with a speed of up to 30 m/s!
Principle advantages of a tunnel metal detector
- Tunnel detector for installation into the conveyer strand. All metal particles are detected and it is both off-shell particles and the ones in the form of inclusions in the end product. High sensitivity in all industrial ambients.
- 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.
The METRON 07 CI tunnel metal detector is:

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.

AMD 07 Control unit
A first-rate control unit is essential for the proper functioning of any detector. Our control unit is made with an emphasis on the high quality of workmanship and components.
The result is a stable control unit with a wide range of functions (just to name a few):
- Communication via Ethernet = unlimited flexibility
- Compact control unit
- Auto-balance including the suppression of interfering signals and automatic sensitivity calibration
- Dynamic auto-tracking – maximum sensitivity in operation
- Multi-filter system using digital filtration for maximum stability in harsh environments
- Self-monitoring system ensures that all important components function properly
- Narrow detection zone provides an accurate location of the metallic particle in the detection field allowing precise separation
- Easy intuitive operation – essential for detector operation
- 5.7" Color display
- Product storage memory backup – for up to 500 products
- Metal detector network and remote service - diagnostics, parameter change, SW update
- USB data media – USB data connection is a standard equipment to store data, carry out easy SW update, upload additional files etc.

The METRON 07 CI can be deployed in both roles: either for quality control of the processed product (detecting metal contaminants in textile materials before dispatch), or for protecting production technology from damage caused by metal objects entering the line. The choice depends on the detector's position in the line and the operational priorities. Both scenarios can be covered by a single unit.
The mesuCAGE technology significantly reduces the required Metal Free Zone (MFZ) — the metal-free area around the aperture that prevents false signals from stationary (conveyor structure, covers) and moving (rollers) metals. A smaller MFZ means easier installation of the industrial metal detector METRON 07 CI into an existing textile production line without extensive construction modifications. We will help you calculate the MFZ for your specific case.
The METRON 07 CI reliably detects metal contaminants at conveyor belt speeds of up to 30 m/s. The dynamic automatic tracking of the AMD 07 control unit maintains maximum sensitivity even at high speeds, and digital signal filtering ensures stability even in environments with vibrations or temperature fluctuations (operating range −10 °C to +50 °C). The detector is therefore suitable even for demanding high-speed textile lines.
The aperture height LH ranges from 50 to 600 mm, the width LB is customizable according to the conveyor width; the detector width SB is always 315 mm wider than LB. A direct relationship applies: the lower the aperture height, the higher the detector sensitivity. To find the optimal dimensions and verify sensitivity for your specific material, we carry out free tests — we guarantee results within three days.
The AMD 07 is integrated directly in the detection head and features a 5.7" colour touchscreen, Ethernet connectivity, a USB port, remote access via mesuNET (remote diagnostics and parameter changes), memory for 500 product settings, and the imagePHASE system for visualising the product and the position of contaminants on the display. Automatic sensitivity calibration and suppression of interference signals ensure reliable operation even in demanding industrial environments.
The detector can be supplied in versions for explosive atmospheres (ATEX), high temperatures, non-standard colour finishes, or with the control unit in a separate cabinet. Optional equipment includes an alarm device (beacon, buzzer), a set of test standards, WiFi, remote access via mesuNET, conveyor control (reverse operation), and contamination rejection systems — pusher, trap door device, air jet, belt reverse or rejection arm.
The standard delivery includes the detection head with the integrated AMD 07 control unit and a user manual — with the control unit built directly into the head, there are no interconnecting cables between units. We provide complete support from the initial site survey and design through custom manufacturing and installation to commissioning, operator training, and authorised service throughout the lifetime of the equipment.
