Traditional single-frequency metal detectors require internal adjustments when faced with handling a product that is different from others inspected on a production line. Usually, this means that an engineer has to be called to retune the detector's frequency, which can take several hours and delay production.

This is the claim made by Carla Whyte, marketing manager of Cintex, which has introduced the Sentry VF digital frequency synthesis system "that allows dozens of frequencies between 40kHz and 900kHz to be 'dialled in' from a control panel". According to Whyte, this allows a 'sweet spot' to be set that maximises metal sensitivity for a product, providing a greater sensitivity and higher accuracy than available previously.

Cintex has also launched the Sentry CodeScan, which has been developed to identify missing, unreadable, and incorrect bar codes "thus helping manufacturers to avoid fines and repercussions as a result of mislabelled products reaching retailers". The unit can be supplied as a complete conveyor with its own reject facility, or can be installed on to existing systems.
