Tunnel metal detector METRON 05 D
The METRON 05 D tunnel metal detector is used to detect metal particles in products transported on the conveyor belts. In addition to the belt conveyor, this demountable tunnel metal detector can also be installed on a vibrating feeder or material slide. Its advantage is that the detector can be divided into two parts and thus easily installed on an existing conveyor without the necessity of demounting the conveyor.
Thanks to its advantageous price, the METRON 50 D is one of the most commonly used tunnel detectors.
Principle advantages of a tunnel metal detector
- Demountable metal detector for installment on a conveyer strand, vibrating feeder or material chute.
- All metals both free and hidden in the material are detected.
- Reliable and in the practice proven technology.
- Investment portecting a valuable machinery against penetration of metals.
- High level exactness of detection evenb in the rough conditions of industry.
- Quick and easy assembly.
The METRON 05 D tunnel metal detector is:
- Reliable – in process and detection
- Durable – in technology and performance
- Easy – in installation and handling
Optional equipment
The METRON 05 D detectors can be supplied with a wide range of additional equipment:
- Signal units – beacon, buzzer, beacon with siren
- Remote reset of the device

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.
