Tunnel type metal detector Multiscan Sentinel 5000™

for conveyorheavy-dutydigital

Brief description
The Multiscan Sentinel metal detector from Thermo Scientific scans up to five selectable frequencies simultaneously to detect ferrous, non‑ferrous and stainless steel contaminants in demanding food processing applications.

Product description
The Multiscan Sentinel combines multi‑frequency scanning (50–1000 kHz) with advanced signal processing to overcome limitations of single‑ or dual‑frequency systems. Designed for high‑effect products such as dairy, meat, poultry and bakery lines, the Sentinel improves contaminant detection while maintaining compact dimensions and compatibility with existing APEX 500 installations for straightforward upgrades.

Main features

• Multiscan: user‑selectable scanning up to five frequencies (50–1000 kHz).
• Detects contaminants up to 70% smaller in volume than previous technologies (e.g., APEX 500), enabling higher sensitivity without major line changes.
• User‑friendly touchscreen with guided setup to reduce commissioning time.
• Detailed graphical displays for phasing, reject diagnostics, verification tests and threshold management to support fine tuning and troubleshooting.
• IP69K washdown rating and dust protection for harsh cleaning cycles.
• Integrated electronics for simplified expansion and flexible system integration.
• Software‑implemented balance functions — no manual field balancing required.
• Wide operating temperature options and specific HD/PVDF liner choices for elevated temperatures or harsh washdown environments.
• Standard test pieces for ferrous, non‑ferrous and 316 stainless steel verification.
