Single Sensor Metal Detectors are specialized detector types that excel in identifying metallic contaminants from a specific direction – primarily from the bottom. These robust units are strategically placed and securely attached to the lower part of the feeding conveyor band, making them ideal for operations where foreign metal objects might settle at the bottom of the material flow or be introduced from below.

They are specifically engineered to protect critical downstream machinery, such as crushers, grinders, and shredders, from damage caused by tramp metals mixed into the material. With an effective detection capability for a maximum material stack height of 15 cm passing over the belt, these detectors precisely identify metal objects equal to or larger than 30 mm in size. This critical detection threshold ensures that potentially damaging metals are caught before they can inflict costly breakdowns or downtime. Upon detection, the system immediately provides a clear, multi-faceted alert, including an illuminated visual signal, an audible alarm, and a crucial relay output signal, enabling prompt action to remove the contaminant.

Advanced Technical Features for Superior Performance

Our Single Sensor Metal Detectors are equipped with a comprehensive suite of technical features designed for reliability, precision, and seamless integration into demanding industrial environments:

• Robust Connectivity & User Interface: The system features a durable 2 x 1 mm LIYCY cable, ensuring reliable data transmission even in harsh conditions. An intuitive LCD digital display provides clear operational feedback and allows for precise sensitivity adjustment by giving numerical value, enabling operators to fine-tune detection based on specific material characteristics and contamination risks.
• Flexible Control & Integration: Advanced settings include configurable waiting and delay time, which allows for optimal synchronization with existing conveyor and processing systems. Both automatic and manual reset setting options provide operational flexibility. The detector is equipped with 2 metal relays and 1 fault relay for comprehensive output control and signaling, a sophisticated noise setting to minimize false alarms from product characteristics or environmental interference, and features for product reset and counting for operational monitoring and analysis. Additionally, it offers a unique before or after rivet sensor connection feature, enhancing its adaptability for various belt configurations and operational requirements.
• Reliable Relay Outputs & Environmental Protection: For critical signaling, the detector includes a powerful Warning relay: 6 Amp Changeover and a dedicated Fault relay: 6 Amp Changeover, ensuring robust communication with external control systems to trigger alarms or halt operations. The control Panel: IP 65 rated, signifying its high resistance to dust ingress and protection against low-pressure water jets from any direction, making it exceptionally suitable for demanding and often wet industrial environments.
• Precision Detection & Wide Operating Range: Engineered for critical protection, the system reliably detects metal dimensions to be detected: ≥ 30 mm. It maintains optimal performance across a broad ambient operating temperature: -20 ºC / +40 ºC, guaranteeing consistent functionality in diverse climatic conditions, from freezing cold to hot environments, thereby ensuring uninterrupted protection.
• Optimized Power & Belt Speed Compatibility: The detector operates efficiently on standard industrial power, requiring a stable Voltage: 220±10% 50Hz. It is designed to integrate seamlessly with common bulk material handling systems, supporting a Recommended Feed Belt Speed: 1.49 -1.07 m/s, which ensures accurate and consistent detection across typical conveyor line speeds without compromising performance.

Why Invest in Single Sensor Metal Detectors?

Implementing single sensor metal detectors in your operations offers numerous benefits:

• Prevents Costly Machinery Damage: By detecting tramp metal before it enters crushers, grinders, or shredders, these detectors significantly reduce the risk of extensive and expensive damage to vital processing equipment.
• Minimizes Operational Downtime: Preventing breakdowns directly translates into reduced unscheduled downtime, ensuring continuous production and avoiding costly interruptions.
• Extends Equipment Lifespan: Protecting machinery from impact damage prolongs its operational life, leading to lower capital expenditure on replacements and reduced maintenance costs over time.
• Enhances Operational Safety: Avoiding catastrophic machinery failures also mitigates potential safety hazards for personnel working near the equipment, contributing to a safer work environment.
• Cost-Effective Solution: For applications where bottom-side detection is sufficient, single sensor detectors offer an efficient and more economical solution compared to more complex multi-sensor or tunnel systems.

Applications Across Industries

Single sensor metal detectors are indispensable across a variety of heavy industries where bulk materials are processed:

• Mining and Quarrying: Essential for protecting primary and secondary crushers, screens, and conveyor belts from drill bits, bucket teeth, rebar, and other large metallic debris commonly found in extracted raw materials.
• Aggregates Production: Ensures the purity of sand, gravel, and stone products by removing tramp metals that could damage processing equipment or compromise the quality of the final product.
• Recycling and Waste Management: Vital for identifying and removing large metals from mixed waste streams, protecting shredders, balers, and other sorting machinery from severe damage.
• Cement and Construction Materials: Safeguarding mills and grinders from metallic contaminants in raw materials like limestone, clay, and shale, ensuring uninterrupted production of cement and other building components.
