Detector Array

The detector array is a core sensing component used in food manufacturing for the detection of fish bones in processed products. It consists of multiple individual detector elements arranged in a specific pattern, functioning as the primary interface for capturing signals that reveal bone density variations. The array converts incident radiation, typically X-rays, that have passed through food products into electrical signals. Each element measures the attenuation of radiation caused by bone material, and the coordinated data from all elements creates a detailed spatial map of bone presence within the scanned product. This enables the detection of the presence, size, and location of fish bones, supporting quality control and safety in food processing lines.

The detector array is designed for integration into a Fish Bone Detection Sensor Module, where it serves as the sensing front-end. Its performance is characterized by parameters such as the number of elements (16–64), element pitch (0.8–2.5 mm), sensitivity (≥0.5 mV/Pa), frequency range (0.1–5 MHz), operating temperature (-10–60 °C), storage temperature (-40–85 °C), supply voltage (3.3–5 V DC), power consumption (≤0.5 W), IP rating (IP65–IP67 per IEC 60529), housing material (316L stainless steel per ASTM A240), weight (0.5–2.0 kg), and connector type (M12–M16 per IEC 61076-2-101). These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier.

Materials on file include Cadmium Zinc Telluride (CZT), silicon, and ceramic substrate. The array is housed in corrosion-resistant stainless steel, suitable for industrial food processing environments. The IP rating indicates dust-tight and water-resistant protection, while the connector type follows industrial standards for reliable electrical connections.

For selection, consider the required spatial resolution (element count and pitch), sensitivity to small bones, and environmental conditions. Verification questions should address the exact specifications, compliance with relevant standards, and compatibility with the existing detection system. Maintenance signals include degraded signal quality or inconsistent readings, which may indicate element failure or contamination. Failure boundaries include operation outside the specified temperature or voltage ranges, which can degrade performance or cause permanent damage.

The detector array operates by converting incident radiation (typically X-rays) that have passed through food products into electrical signals. Each detector element in the array measures the attenuation of radiation caused by bone material, with the coordinated data from all elements creating a detailed spatial map of bone presence within the scanned product. The array's design allows for high-resolution detection of bone density variations, enabling the identification of fish bones in processed food.
