A new metal detector has been launched by Constant Instruments, offering sensitivity up to 30% higher than earlier models. The THS/MS21 metal detector, suitable for use in bakeries, can detect contaminant particles at high speed, even for difficult highly conductive products, such as those containing high levels of salt or fat.

Non-magnetic as well as magnetic metals can be detected, including high-grade stainless steel, and if a product is identified as containing a contaminant, the unit triggers immediate ejection of the product. Data relating to each detection is stored, and the detector constantly monitors its detection characteristics, allowing continuous compensation for any variations arising from environmental factors. It has an exclusive Autolearn feature, which optimises detection sensitivity for maximum speed and precision.

A control system manages all functions including belt monitor control and ejection management.
