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.
Principle advantages of a gravity free-fall style metal detector
- Metal detector with a round opening for installment into transport pipeline system. 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 even in the conditions of rough industrial use.
- User friendly and reliable technology proven by the use of many years.
- It is used either for quality control of the product being processed or as a protection of subsequent machinery.
- Individual solution on the basis of removable tube and retaining frame.
The METRON 05 CR gravity free-fall style metal detector is:

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.

The METRON 05 CR is a cost-effective free-fall metal detector with an attractive price-to-performance ratio — the right choice for applications where budget matters and the advanced features of the AMD 07 control unit are not required. Compared to METRON 07 models, it features the AMD 05 control unit with an LCD display and four buttons instead of a colour touchscreen, and requires a Metal Free Zone. On the other hand, it covers a significantly wider pipe diameter range — from 35 to 600 mm.
Sensitivity depends on the aperture diameter — the smaller the diameter, the higher the sensitivity. It is also influenced by material speed (recommended range 0.05–1.5 m/s), product density, temperature and humidity. We will verify the exact sensitivity values for your application with a free material test — contact us to arrange the shipment of samples.
We supply the METRON 05 CR as standard for pipe diameters from 35 to 600 mm. On request, we manufacture individual solutions with a different height, aperture diameter or frame to suit your specific installation. The AMD 05 control unit is mounted on the detector frame as standard, but can be installed remotely if required.
The Metal Free Zone (MFZ) is a protective space around the detector aperture that must not contain any moving or stationary metal — metal structures, covers or rollers would cause false signals and unnecessary product rejection. The METRON 05 CR requires an MFZ; the detector aperture must be positioned at the centre of the MFZ. We are happy to help you calculate the MFZ for your specific installation.
The AMD 05 control unit features a five-line LCD display and is operated via four ergonomic buttons — operation is simple and intuitive. It offers automatic product setup with interference signal suppression and automatic sensitivity calibration, digital signal filtering, continuous system function monitoring and memory for storing settings for up to 500 products. Remote connection for diagnostics, parameter changes and software updates is available as an option.
The detector operates at temperatures from -10 to +50 °C and relative humidity of 0–95% without condensation. The protection rating is IP 65, power supply 100–240 V AC (50/60 Hz), maximum power consumption 50 W. The recommended material speed for reliable detection is 0.05–1.5 m/s.
We supply the METRON 05 CR in an ATEX version for use in explosive atmospheres, in an Alutron version (patent no. 4342826) eliminating false signals caused by metallised foil, in a high-temperature version, or in a non-standard colour on request. Optional accessories include warning devices (beacon, buzzer), visual marking and contaminant rejection (rejection flap, three-way ball valve), plastic sensor tubes, mesuSET software for laptop control, the mesuNET system for remote access and test pieces.
Standard delivery includes the detection head, AMD 05 control unit, connection cables, installation hardware and operating manual. After installation, we carry out commissioning, operator training and provide authorised service throughout the entire operating period. We perform free material tests before purchase — we guarantee tests within three days of receiving your samples.
