M/s. EGE-Elektronik Spezial-Sensoren GmbH (Germany) manufacture Metal Detection System 3000 which detects metal parts in non-metallic environment especially in-feed system of conveyors. This prevents damage of valuable machinery if metal parts enter a stone crusher or similar material handling system. The detection system comprises an amplifier and a detector coil and works on the inductive principle. The amplifier has an automatic regulation adjustment which ensures that metal parts are detected only when they are in motion. The sensitivity can be adjusted.
The above system is supplied as a loose detector coil and an amplifier unit suitable for 230 V.AC or 24 V.DC. The systems 3000 and 3300 can be used to check and give information of entry of undesired metal part in the in-feed system or material handling systems like sugarcane crushers, cement and stone crusher conveyors, wood chipping conveyors & vibratory feeders. The system 3300 has higher sensitivity and can detect smaller metal parts. The system forms a reliable protection to valuable machinery.
