Metal Detection for Tablets

The THS/PH21N-FB Metal Detection System from CEIA allows for the detection of extremely small metal particles on all types of tablets, with automatic rejection of any product that fails to meet the required standard. It boasts an impressive throughput rate of 40,000 – 60,000 tablets/hr and is capable of processing tablets up to 35mm in diameter.

The metal detector has ultra-high sensitivity to all magnetic and non-magnetic metals, enabling specific inspection against extremely small metal particle contamination. It is capable of storing an impressive 500 product profiles for different items being produced and these are selectable by local operator programming or remote network software. The system will also store up to 10,000 events for quality control purposes, or 100,000 events if the IXC network board option is included

The flat conveyor based inspection system has a digitally adjustable belt speed and a high immunity to any environmental interference. It also has an automatic ejection management mechanism with synchronisation with the product as it transits through the detector. This includes verification of the successful ejection of the contaminated product. 

The system comes with a buzzer and three-coloured warning lamp (to signal alarm, fault and test request), along with a “bin full” photocell and air pressure kit. In addition, mounting and dismounting of the belt is designed to be very easy. The complete system is designed to be easy to maintain and inspect.

The THS/PH21N-FB is fully compliant with pharmaceutical sector regulations.

The Reference Sensitivities are as follows:

  • FE = 0,3 mm
  • NFE = 0,35 mm
  • AISI 316 = 0,5 mm
