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.

The P-TRON 03 FM is an economical pipeline metal detector with an attractive price-to-performance ratio and fast return on investment. Unlike the P-TRON 05 GM V1 and V2, it is equipped with the AMD 03 control unit, which offers a simpler feature set. Sensitivity at aperture Ø38 mm reaches Fe 0.6 mm, compared to 0.4 mm for the P-TRON 05 GM V2. The ATEX version for use in explosive atmospheres is not available for the P-TRON 03 FM — this certification is offered for the P-TRON 05 GM V1 and V2 models. The P-TRON 03 FM is the right choice where maximum sensitivity and operation in explosive environments are not required and where low acquisition cost is the primary criterion.
We supply the P-TRON 03 FM as standard with aperture diameters from 38 to 80 mm — available sizes are 38, 45, 50, 55, 60, 65, 70, 75 and 80 mm. The detector can be installed in both horizontal and vertical pipework. Conveying speed reaches 0.5 to 30 m/s, operating range is −10 °C to +50 °C, protection rating IP 54. For non-standard diameters, heights or frames we supply custom versions.
Sensitivity depends on aperture diameter, material speed and density, temperature and moisture. Indicative values: for apertures Ø38–60 mm it detects Fe and NonFe spheres from 0.6 mm diameter, stainless steel (SS) from 1.0 mm. For apertures Ø65–80 mm: Fe 0.9 mm, NonFe 1.0 mm, SS 1.5 mm. The detector captures both free metal particles and metals concealed as inclusions inside the material. For precise sensitivity verification for your specific application we carry out tests free of charge — results are guaranteed within three days.
The detector is built directly into the vacuum pipeline. Material passes through the detection coil; when a metal contaminant is detected, a high-speed rejection flap with a switching time of 0.05 s opens automatically, the contaminant together with a portion of material is diverted to the reject chute and the flap returns to its original position. Rejection time is adjustable, losses of good material are minimal. No Metal Free Zone is required — the detector can be connected directly to existing metal pipework, so installation is fast and requires no extensive modifications to the line.
Optional equipment includes a warning device (beacon or buzzer) and a rejection cycle counter. If the standard size range (Ø38–80 mm) does not meet your requirements, we supply versions with a different height, aperture diameter or frame to match specific production needs. The standard delivery includes the detection head, AMD 03 control unit, connecting cables and user manual.
The P-TRON 03 FM is most commonly used for inspecting plastic materials (granulate, regranulate, flakes) conveyed in vacuum pipelines, but it is suitable for any process with bulk materials in pneumatic conveying. Typical customers include recycling operations and plastics manufacturers. We visit you on site, take measurements and propose a solution, manufacture and install the equipment to specification, commission it and train your operators. We provide authorised service throughout the entire service life of the equipment.
