Lock Gets High Tech



In April this year, Lock Inspection Systems launched a new state-of-the-art high frequency metal detector. Based on the proven advanced technology of Lock's MET 30+, the latest addition to its portfolio offers food manufacturers and packers heightened sensitivity for non-ferrous and stainless steel metals - up to 30% higher than standard detectors.

The MET 30+ hf detector remains robust and reliable at peak sensitivities by employing a single high frequency, crystal controlled oscillator. Designed primarily for snack food and bakery industries, the unit will inspect dry foods such as biscuits or crisps at 875Khz - four times more than standard food industry detectors. The MET 30+ hf eliminates the need to reconfigure the settings for each product, reducing downtime while increasing efficiency and operating speeds.

Flakes or slivers from machinery as well as swarf or wire from sieves, cutters or drilling during maintenance work can infiltrate the line at any stage during the production process. It is the pure, high resistance non-ferrous and stainless steel metals that pose major challenges to standard metal detectors. The MET 30+ hf can guarantee the highest level of product integrity available, offering peace of mind for food manufacturers.

The system is currently available as a horizontal unit, employed at the end of the line for final screening of dry, polywrapped, finished products. Lock is developing a Waferthin model for space-restricted lines as well as a Vertical Fall option for free-flowing goods such as coffee granules, sugar and cocoa later this year.

The MET 30+ hf detector is available with a touchscreen keypad incorporating Lock's proprietary ADC software which displays signals from the metal detector in graphical format. Data can be viewed on-screen so any changes in signal can be identified immediately and the detector adjusted to match the product being inspected. This delivers accurate detection of the minutest particles of metal - whatever the product profile.

Mark D'Onofrio, Vice President General Manager at Lock comments: "We developed the MET 30+ hf detector in response to industry demand for improved sensitivity on non-ferrous and stainless steel metals for dry applications. We have built on the proven electronics of the MET 30+ detector that have earned us world-wide recognition. A single, ultra-high frequency guarantees the highest levels of sensitivity, which means food manufacturers can rest assured their products are inspected to the highest standards".

Based in Fitchburg, Massachusetts, and Oldham, UK, Lock Inspection Systems supplies metal detection and checkweighing equipment to food manufacturers worldwide. A global network of offices and distributors enables Lock to deliver the highest standards of customer service and after sales care.
