Cassel Metal detectors TRACEABILITY – A HIDDEN THREAT
Legislation
and the contractual demands of the larger Supermarket chains, means that
suppliers have to have a system for Metal Detection and traceability so that
metal contamination is detected reliably, the cause determined quickly and
results recorded for future investigation. Suppliers without a tightly run system
are at risk legally and commercially.
The
problem is that metal contamination, being an infrequent occurrence, can go
unrecorded in the hectic environment of a production area.
Most
importantly detectors, which are very sensitive instruments, can drift into
error missing contamination or falsely rejecting items. For this reason their operation has to be
checked regularly and sensitivity adjustments made. Standard calibration procedures employing
specified test pieces are used at specified intervals. Results have to be logged and available for
inspection.
Ultimately
the retailers are responsible to the general public and are at most risk from
contaminated product. To be certain that suppliers are meeting the necessary quality
standards Supermarket chains are looking to collect Performance Data including
calibration results, direct from their suppliers’ detectors over the web,
storing the information in secure data
bases containing the history of
individual items.
Metal
Detectors with Ethernet connectivity that meet this requirement are now
becoming available with software that automatically logs calibration results
and any contamination incidents.
The
most advanced of the new generation of smart detectors is Cassel’s Shark2 with
Sharknet software. It goes beyond basic
logging, enabling completely remote operation of the detector. It gives a view
of the detector screen in real time so that operation can be reviewed and
set-up for new products, all from a remote point away from the production area. Beyond this, through the software’s Team
Viewer facility, Cassel Technicians here
in the UK and at the Cassel Service Centre can be called upon to interrogate
the detector providing advise, modifying
settings and functions if necessary.
