Weighing and Foreign Object control in Challenging Conditions

Weighing and inspection solutions represent critical control points within production – so absolute precision is required in the results. However, outdoor production facilities often have to contend with problems such as electrostatics, temperature fluctuations, wind load or the risk of explosions and earthquakes. Minebea Intec offers solutions that can cope with all environmental conditions.

External factors can have a major influence on the results of weighing or foreign object detection. While seismic forces, air pressure or temperature fluctuations during weighing can falsify the result, influences during the detection of foreign objects lead to a different product effect, which makes metal detection more difficult. The company, as a leading supplier of weighing and inspection solutions, offers numerous options to ensure reliable weighing and foreign object detection nevertheless.

When temperature differences make no difference: Metal detection with reliable results

In production environments, accuracy and immunity to interference are important parameters for metal detection. But extreme or changing weather conditions make detection a real challenge. This is what happened at TCDRI, a construction company that builds cement factories around the world. A plant in the Caucasus Mountains, Russia, had to contend with particularly harsh temperature variations: ambient temperatures ranging from -45 °C in winter to +20 °C which are not uncommon in this region. Such temperature fluctuations lead to a stronger product effect and make reliable metal detection more difficult.

Products in the Secus series are therefore equipped with a learning function that adapts to ambient conditions by compensating for the product effect. Secus metal detectors work reliably and without false alarms even at low temperatures, strong wind or vibrations in the environment.
