Throat metal detectors from METTLER TOLEDO are designed to inspect products going through a Vertical Form, Fill, and Seal (VFFS) process, and reject metal contaminants at a designated critical control point.
Our vertical metal detectors are ideal for inspecting free-falling products in processing and packaging lines, particularly when using metallized packaging. They detect unwanted metal in the product flow before it enters the bag, effectively overcoming interference to achieve high sensitivity levels.
Choose from three models to meet your requirements:
- Throat Signature – High-Tuned Frequency technology ideal for less demanding applications
- Throat Profile (T Series) – Multiple Ultra-High Tuned Frequency ideal for inspecting free-falling products in restricted insertion spaces
- Super Throat Profile (ST Series) – Multiple Ultra-High Tuned Frequency ideal for high speed vertical packaging applications when maximum sensitivity is required. The Super Throat benefits from optimized coil geometry for improved detection capability.

Avoid Manual, Invasive Metal Detector Testing at Height
Vertical fall metal detectors are often placed in hard-to-reach areas, requiring operators to work at heights. The Automatic Test System from METTLER TOLEDO significantly reduces this risk. The benefits include:
- Increased productivity: Tests are completed in 40 seconds.
- Non-invasive testing: To preserve hygiene and product quality.
- Improved worker safety: There is no need for operators to manually drop test samples through the opening, eliminating the risk of working at heights or stretching across other production line equipment.
- Accurate and repeatable tests: Supports compliance by confirming centerline (worst-case) sensitivity performance.
- Automated record keeping: When combined with ProdX software, test results from ATS are automatically recorded and stored, taking food safety processes to the next level.
Maximum Sensitivity and Performance
Both the T and ST Series metal detectors feature integrated Multiple Ultra-High Tuned Frequencies combined with eDrive capability, Enhanced Vibration and Enhanced Noise Immunity. These features provide exceptional sensitivity for consistent metal detection.
Throat Signature metal detectors come with a durable push-button membrane key panel for easy operation. Auto-Balance Control and onboard fault reporting work together to create a stable operating platform, helping to minimize potential downtime.
Simple to Use with Ease of Integration
The metal detectors can be operated using an easy-to-use icon-driven touchscreen (T and TS Series) or a menu-driven key panel (Throat Signature). The Zero Metal Free Zone technology reduces the insertion space between the multi-head weigher and bagmaker while maintaining sensitivity performance.
