Gravity free-fall style metal detector QUICKTRON 05 A

The QUICKTRON 05 A is designed as an economical option with an attractive price-to-performance ratio — combining high sensitivity through digital signal processing with a robust construction for maximum service life. Compared to the QUICKTRON 03 R, it offers a wider aperture range (DN 50–300 mm versus DN 30–200 mm) and the more advanced AMD 05 control unit with automatic product setup, automatic calibration, and memory for up to 500 product settings. These features make it the most frequently used gravity fall detector for inspecting bulk materials transported by free fall.

The detector is designed for bulk materials transported gravitationally through pipelines — most commonly granules, regrind, flakes, and ground material in the plastics and recycling industries, as well as chemical, rubber, and mechanical engineering applications. It is also used in the food industry, for example in the production of spices and dried herbs, where reliable elimination of metal contaminants from free-falling product is essential. The detector protects downstream equipment (injection moulding machines, extruders) from damage caused by metal contamination and helps maintain the quality of the final product.

Sensitivity depends primarily on the aperture diameter — the smaller the diameter, the higher the sensitivity. For the QUICKTRON 05 A with the smallest aperture of DN 50 mm, we can detect a steel sphere from 0.3 mm; for the largest standard aperture of DN 300 mm, the minimum detectable size is 1.75 mm. Material speed (1.5–6.0 m/s), density, temperature, and moisture content also influence sensitivity — we therefore recommend verifying the parameters with a free test using your specific material.

We supply detectors for pipeline diameters from DN 50 to DN 300 mm as standard. On request, we can supply a detector with a different height, aperture diameter, frame configuration, or even a non-standard pipe cross-section (square, rectangular) to suit the specific requirements of your production process.

The AMD 05 control unit provides automatic product setup with interference signal suppression, automatic sensitivity calibration, digital signal filtering for stable operation in demanding environments, and continuous system function monitoring. It is operated using 4 ergonomic buttons and a five-line backlit LCD display; settings for up to 500 products can be stored in memory. The unit can be mounted directly on the detector frame or installed remotely. Optional accessories include warning devices (beacon, buzzer), air pressure and flap position monitoring, an air compressor, and a compressed air vessel.

Yes, we supply the detector in a full range of special versions — including ATEX-certified versions for use in potentially explosive atmospheres, high-temperature versions, versions for pressurised applications up to 0.3 bar, and fully stainless steel versions (grade 1.4301 / SS 304). When enquiring, please specify the required ATEX zone and category, or the specific operating conditions, so we can propose the appropriate configuration.

The standard supply includes the detection head, the rejection unit with pneumatic components and air pressure regulator, the AMD 05 control unit, connecting cables, installation hardware, and a user manual. The low installation height and compact dimensions make it easy to integrate into existing pipelines without major structural modifications. We manage the entire project — we visit, measure, manufacture to specification, install, commission, and train your operators; authorised warranty and after-sales service is also included.

Yes — we carry out tests of your material on our equipment free of charge, with a guaranteed result within three days. Tests are particularly important for correctly determining the sensitivity of the detector, as performance depends on the specific material and operating conditions. Simply contact us, we will arrange the sending of samples and prepare a test report.
