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/21 & THS/MS21 series 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/21 and THS/MS21 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
