Metal detectors METRON 05 CR for gravity
Thanks to its low height and compact dimensions, the METRON 05 CR detector is easily integrable into the existing pipeline.
The simple METRON 05 CR with round aperture is used to detect metal particles in pipe-transported bulk materials.
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.
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.
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:
- Reliable – in process and detection
- Durable – in technology and performance
- Comfortable – in design and data management
Optional equipment
The METRON 05 CR detectors can be supplied with a wide range of additional equipment:
- Signal units – beacon, buzzer, beacon with siren
- Visual markers – color marking of contaminants
- Reject systems – flap valve systems for bulk materials, 3-way ball valves
- Plastic sensing tubes – with transitions, funnel or flanges
- MesuSET – operation of detector via laptop
- MesuNET – network integration and remote maintenance
- Test etalons
Special design
Do you have special requirements for a metal detector design? The most common requirements include:
- Explosion proof versions
- Visual marking of the detected contaminants = color coding
- Designed even for use at high-temperatures
- ALUTRON version – suppression of interference signals from metalized foils – Patent No. 4342826

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.
