THS/PH21N-FB
Detection of very tiny metal particles on effervescent tablets with automatic rejection
The THS/PH21N-FB system, crafted in AISI 316L stainless steel, delivers excellence in pharmaceutical and food quality control. Featuring ultra-high sensitivity and superior interference immunity, it accurately detects all metals, including stainless steels. Advanced Auto-Learn and product effect tracking functions optimize performance, while AUTOTEST and AUTO-QC protocols ensure continuous self-diagnosis. The system manages the entire synchronized ejection cycle with scrap verification, guaranteeing production line integrity and full traceability of eliminated contaminants.Key Points
Construction Quality and Hygienic Standards
The THS/PH21N-FB system is engineered to excel in the most rigorous production environments. The structure is entirely made of AISI 316L stainless steel, a material chosen for its exceptional corrosion resistance and ease of sanitization. This architecture guarantees long operational life and full compliance with the hygienic standards required by the pharmaceutical and food sectors.
Detection Technology and Sensitivity
The device boasts ultra-high sensitivity to all types of metal contaminants, including magnetic, non-magnetic, and difficult stainless steels. To ensure consistent performance even near heavy industrial machinery, the system features high immunity to environmental interference, minimizing electromagnetic disturbance and ensuring stable, precise monitoring.
Automation and Product Management
Integrated intelligence allows for dynamic interaction with the product in transit:
- Auto-Learn: Rapid and precise calibration for different product types.
- Product Effect Tracking: Automatic compensation of signals derived from natural product characteristics (moisture, salinity, presence of active ingredients).
- Variable Speed: The conveyor belt is digitally adjustable to synchronize perfectly with production line rhythms.
Security Protocols and Self-Diagnosis
Operational continuity is supported by advanced AUTOTEST and AUTO-QC functions. These tools perform periodic, automatic quality checks on system operation, certifying that detection capability remains constant over time without requiring invasive manual intervention or prolonged downtime.
Line Integrity and Rejection System
The THS/PH21N-FB serves as an integrated inline control system, managing the entire ejection cycle:
- Synchronization: Automatic ejection is coordinated with the exact passage of the contaminated product.
- Reject Verification: The system goes beyond sending an ejection pulse; it verifies actual elimination, ensuring that no non-compliant product proceeds to the packaging or distribution stage.
