An automatic selection function allows the Metal Detector to choose the optimum frequency for the product in transit during the autolearn phase.

The automatic tracking function eliminates any further variations due to the “Product Effect”. The wide pass band of the Metal Detector allows operation at maximum sensitivity at both slow and fast speeds.

The digital analysis of the signal provided by the probe allows the user to achieve extremely high sensitivity, immunity to interference and operational stability.

FDA 21 Part 11 compliant

The THS/21ET Metal Detector Series is a high-sensitivity, high-precision measuring instrument. The data relating to each detection and ejection are stored in an events memory and certify production quality, the inspection itself and programming operations, as well as the periodic functional test phases using standard test samples.

FDA Code Title 21 Part 11 prescribes rigorous criteria for access to programming and computer data protection which have been fully adopted in the THS/21ET Series firmware.

The requirements regarding Security, Integrity and Traceability are therefore satisfied.

Exclusive auto-learn system

The THS/21ET Series employs an exclusive Auto-Learn system for food products which provides simultaneous maximum sensitivity to all metals starting from a single learning transit.

The system allows optimization of the detection sensitivity to all metals with the maximum speed and precision, equivalent to hundreds of conventional learning transits: these results in high levels of precision and efficiency.

Real-time embedded self-calibration control

The Self-Calibration control allows maximum repeatability and performance consistency over time and with environmental changes.

By means of specific signals sent to the transmission and reception chain of the Metal Detector, constant monitoring of the detection characteristics is carried out, with consequent constant compensation for any variations caused by environmental factors.

The result is system stability and consistency in detection performance and product effect neutralization.

Automatic verification of the installation quality and environmental compatibility

THS/21ET Series introduces new tools for the installation and maintenance technicians which allow them to measure the environmental compatibility of the Metal Detector.

The measurements include general mechanical and electromagnetic environmental compatibility, specific electromagnetic compatibility and the automatic examination of the degree of metal interference from the conveyor belt.

This latter function becomes even more important when the high level of sensitivity of the THS/21ET Metal Detector Series is taken into consideration.

BT connectivity

In the THS/21 Series, local connection to the maintenance technician’s computer no longer requires physical access to the interior of the detector or the use of unwieldy connection cables.

The BT connection can be used for programming, monitoring of the signals via the CEIA MD-Scope program and the transfer of the data contained in the Metal Detector’s events memory.

AUTOTEST and AUTO-QC™ TEST functions

Industrial Metal Detectors for food application are usually equipped with basic diagnostic functions based on their emitter/receiver signals monitoring.

This type of diagnosis is not able to detect aging as well as thermal drift and other sources of minor deviations. Any of the above may result on a sensitivity reduction that could lead to non-detection of metal contamination.

THS/21ET metal detectors are natively equipped with an advanced AUTOTEST function ensuring the following features:

• Continuous background real-time monitoring and stabilization of the amplitude and phase response for each working frequency
• Continuous compensation of environmental and age-related changes
• Immediate alerting in case of permanent out of standard conditions

In addition to the AUTOTEST function, THS/21ET and THS/ET-3F detectors can be programmed so that periodic verifications of the calibration are carried out automatically. This feature is called AUTO-QC™ TEST.

• The AUTO-QC TEST allows the manual verification of calibration by the operator to be reduced or eliminated
• The METAL DETECTOR provides a programmable output that can be connected to the conveyor line stop during the AUTO-QC test to avoid product ejection and waste during automatic test
• CEIA AUTO-QC TEST provides an effective calibration check along with a programmable 0 ÷ 100 % reduction of the manual verifications, resulting in a corresponding reduction of: Labour cost; Accidental product contamination; Product waste
