Metal detector for the installation in gravity of vacuum/pressure conveying lines METRON 05 CR
The simple METRON 05 CR with round aperture is used to detect metal particles in pipe-transported bulk materials.
Thanks to its low height and compact dimensions, the METRON 05 CR detector is easily integrable into the existing pipeline.
The METRON 05 CR excels in in the low price while keeping the required detection standards. We supply this free-fall style metal detector for pipes with a diam. of 35 – 600 mm as standard.
This detector is equipped with a powerful AMD 05 control unit with a range of advanced features such as automatic product setup, automatic calibration and the digital filtration system. The unit is equipped with a 5-line LCD display and is controlled with 4 ergonomic buttons. Its operation is simple and intuitive. The control unit is installed on the detector frame, but it can also be placed in a separate housing outside the detector.

We can supply units with different height, inside diameters, frames, etc. to meet your requirements.
We will ask you to specify the required modifications so that the offer can be elaborated exactly according to your requirement.
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.

Gravity free-fall metal detectors are specialised devices designed to inspect bulk and freely flowing materials that pass through a pipe or channel under the force of gravity. They are installed in production lines of the food, pharmaceutical or chemical industry, where they detect and automatically reject metal contaminants before further processing or packaging of the product.
We offer six models of gravity free-fall metal detectors for the food industry: Metal detector METRON 07 PowerLine, Metal detector METRON 07 FlatLine, Metal detector QUICKTRON 07 RH HyQ Clean, Metal detector QUICKTRON 05 A, Metal detector METRON 05 CR, and Metal detector PHARMATRON 07 HQ. Each model is designed for specific applications and differs in sensitivity, design and control unit.
Sensitivity depends on the specific model and aperture diameter. For example, the Metal detector METRON 07 PowerLine achieves sensitivity of up to 0.4 mm for ferrous metals (Fe), 0.5 mm for non-ferrous metals (NFe) and 1.5 mm for stainless steel (SS). The Metal detector QUICKTRON 07 RH HyQ Clean detects Fe from 0.5 mm, NFe from 0.6 mm and SS from 1.5 mm. Exact values always depend on the aperture diameter and the properties of the inspected product.
The Metal Free Zone (MFZ) is a protective area around the detector where no metal structures must be placed, to avoid interference with detection. The Metal detector METRON 07 PowerLine and Metal detector METRON 07 FlatLine do not require a Metal Free Zone thanks to their special design concept, which greatly simplifies installation and saves space on the production line. The Metal detector QUICKTRON 05 A and Metal detector METRON 05 CR do require a Metal Free Zone.
A gravity free-fall metal detector operates on the principle of electromagnetic induction. The material falls freely through the detection head under gravity, which generates an electromagnetic field. If the material contains a metal contaminant, it causes a change in this field, which the device immediately registers. The control unit then activates an automatic ejector that removes the contaminated product from the production process.
The detectors are equipped with two types of control units. The models QUICKTRON 07 RH HyQ Clean, METRON 07 PowerLine, METRON 07 FlatLine and PHARMATRON 07 HQ use the AMD 07 unit with a 5.7" colour touch display, Ethernet connectivity, remote mesuNET access and memory for 500 products. The models QUICKTRON 05 A and METRON 05 CR are equipped with the AMD 05 unit with a 5-line LCD display, 4 buttons and memory for 500 products.
Yes, our gravity free-fall metal detectors are certified and designed for the food industry — they meet hygiene requirements and are made from materials suitable for contact with food. The Metal detector PHARMATRON 07 HQ is specifically designed for the pharmaceutical industry with the highest demands on hygiene and detection sensitivity. All models comply with applicable standards and regulations in force in the EU.
We provide comprehensive service support including installation, commissioning, operator training and regular calibration. To verify correct detector function, test pieces are available for regular sensitivity checks. Customers can also use the mesuNET remote access for monitoring and managing detectors over the network — available on models with the AMD 07 control unit.
