Pipeline metal detector P-TRON 03 FM
The cost-effective P-TRON 03 FM pipe metal detector is used to detect and reject metal particles from vacuum-fed bulk materials. It is designed for installation into vertical and horizontal pipes. It is often used to detect metals in plastic material (granules, re-granulate, plastic flakes).
The detector is fully automatic, equipped with a high-speed reject flap that instantly diverts the detected contaminant from the product stream and minimizes the loss of a good product.
The main advantages of this metal detector include the low price (resulting in a very fast return on investment) and easy installation.
We supply this detector with an inlet opening of 38 – 80 mm as standard.
The control unit is very simple to operate, stable and durable.
Principle advantages of a pipeline metal detector
- Detection of metals for compressed-air pipelines without the interruption of the flow of material
- All metals both free and hidden in the material are detected and separated automatically
- Flexible building-in into the existing pipeline distribution systems – regardless of the direction of material flow, quickly and cheaply
- Convincingly easy control
- Exact and reliable operation
Working principle
The metal detector of the P-TRON series is installed into a pipeline used for the vacuum transport of bulk materials. The inspected material passes through the reject assembly. If the material is contaminated with metal particles, the contaminant in the product stream alters the high frequency field generated by the search coil. The electronics evaluate this signal and generate an impulse for the solenoid valve and double actuating air cylinder of the reject assembly. The contaminant is instantly diverted from the good product stream assuring minimal good product loss. The reject flap then automatically returns to its normal position. The detector operation including the elimination of contaminants is fully automatic.
Thanks to the high-speed reject flap used, its operation is very fast and accurate, enabling minimization of good material loss.The reject time is adjustable.
The P-TRON 03 FM pipeline metal detector is:
- Reliable – in process and detection
- Durable – in technology and performance
- Fast – in response and cleaning
Optional equipment
The P-TRON 03 FM detectors can be supplied with a wide range of additional equipment:

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.

Industrial metal detectors for pressure pipeline transport are designed to inspect bulk materials conveyed pneumatically — both under pressure and by vacuum. They are most commonly used by plastics processors (granulate, regranulate, flakes), textile fibre manufacturers and recyclers, the chemical industry and pharmaceutical operations. The detectors capture free metal particles as well as metals hidden as inclusions inside a granule or fibre, without interrupting material flow.
The detector is integrated directly into the pneumatic pipeline. The material being inspected passes through the detection coil, which captures the signal generated by the presence of a metal contaminant. Upon detection, a high-speed rejection flap opens automatically, the contaminant together with a portion of material is diverted into the reject chute and the flap returns to its original position. The entire cycle is fully automatic. With a switching time of 0.05 s, losses of good material are minimal.
Sensitivity depends on the aperture diameter, material speed, density and other parameters. As a guide: the P-TRON 05 GM V2 with a Ø38 mm aperture detects an iron sphere from 0.4 mm diameter and a stainless steel sphere from 0.8 mm. The P-TRON 03 FM with Ø38 mm detects ferrous and non-ferrous metals from 0.6 mm and stainless steel from 1.0 mm. We recommend verifying the exact sensitivity for your specific application by testing your material — tests are carried out free of charge with a guaranteed result within three days.
We offer aperture diameters from 38 mm (P-TRON 03 FM, P-TRON 05 GM V1/V2) up to 630 mm (METRON 05 PowerLine). All models handle conveying speeds from 0.5 to 30 m/s. We install detectors in both horizontal and vertical pipelines. Non-standard diameters and geometries are handled individually to order — contact us with your specification.
The P-TRON 03 FM, P-TRON 05 GM V1 and P-TRON 05 GM V2 models do not require a Metal Free Zone — they can be connected directly to existing metal pipelines. The METRON 05 PowerLine uses a patented design that allows integration without an additional sensor tube, making it immune to electromagnetic interference from the surrounding structure. Installation is fast in all cases and requires no extensive modifications to the line.
The High-Speed TEXREJECT eject gate is a high-speed rejection unit designed for use in combination with the METRON 05 PowerLine detector. It is used in applications where material passes through the pipeline at speeds of up to 30 m/s — typically textile fibres or granulated raw materials. With a switching time of 0.05 s and a robust construction rated for 300,000 rejection cycles without visible wear, it enables precise rejection of metal contaminants with minimal losses of clean product. The unit is suitable for both pressure and vacuum conveying.
