CEIA THS/PH21 Metal Detection Systems offer detection, construction quality and reliability characteristics that make them the most suitable and effective solution to automatic elimination of metal contaminants. Validation Solutions Available: Calibration Standards; Validation Manuals; Comprehensive Service & Support; Compliance Tools; On-line Production Data Validation. CEIA Metal Detectors are specially engineered so that no manual calibration or tuning is needed. CEIA Metal Detectors have an internal Auto-diagnosis for automatic balancing of the antenna with continuous embedded Self-Calibration control.

THS/PH21N THS/PH21E - detail

CEIA THS/PH21N Metal Detection Systems feature extremely high detection sensitivity towards contaminating metals, whether ferrous, non-ferrous or stainless steel, even when these are present in tiny quantities

FDA 21 Part 11 Compliant

The THS/PH21 Metal Detector Series is a high-sensitivity, high-precision measuring instrument. The response from the device is used to directly command ejection of the contaminated product and to verify that it has in fact been eliminated.

FDA Code Title 21 Part 11 prescribes rigorous criteria for access to programming and computer data protection, which have been fully adopted in the CEIA THS/PH21 Series firmware. User access is only possible via a User Name and Password login under the control of the System Administrator, who programs and manages individual user profiles and user functions. As a result, the requirements for security, integrity and traceability are satisfied.

All events performed by the THS/PH21 Metal Detector are recorded in a data log to comply with FDA Part 11 protocol and assist in root cause analysis. The events include detection, ejection, program operations, passwords and periodic functional test phases using standard test samples.

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 constancy in detection performance and product effect neutralization.

Exclusive auto-learn system

The Auto-Learn System provides simultaneous maximum sensitivity to all metals starting from a single learning transit. The THS/PH21 Series employs an exclusive Auto-Learn system for pharmaceutical products, which allows optimization of the detection sensitivity to all metals with the maximum speed and precision, equivalent to hundreds of conventional learning transits. This results in levels of precision and efficiency never before obtained.

Continuous auto-test function

Special electronic stimuli are sent to the transmission and reception chain of the THS/PH21 Series Metal Detector, causing variations in the detection signals which provide checks on detection characteristics. These variations are compared with the reference values stored in the memory of the metal detector at the time of the factory calibration test. This produces an automatic certified check of the system’s sensitivity.

CEIA automatic calibration test

To comply with the daily Metal detection and ejection verification requirements, the CEIA Metal Detectors THS 21 Seriesprovide:
  • A full digital internal structure, completely free from internal trimmers to be calibrated, as the analog processing has been replaced by digital numerical analysis.
  • An automatic, wide dynamics, antenna balance tracking system to maintain in-range performances in all installation environments.
  • A continuous embedded Self-Calibration control.
  • A continuous Auto-Test function which generates stimuli corresponding to the manual metal samples transits.
  • A calibration test in automatic mode. During the automatic test, the Metal Detector generates a stimulus equivalent to the same excitation signal of the last manual test, verifying the correct activation of the alarm and the ejector. All test results are recorded into the Events buffer and are available for data traceability. The THS 21 Series provides the possibility to determine and program the mix of manual and automatic test operation in a wide ratio range, depending on the User Quality procedures, through the MTI parameter.

  • Advanced mechanical and electronic solutions guarantee the integrity of the inspected product
  • Extremely quick response time provides full safety in the ejection of contaminated product
  • Double confirmation system carefully monitors and controls the complete opening and closing of the ejection flap
  • Bin full sensor kit (on request)

BT Connectivity

In the THS/PH21 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.
