Thermo VersaWeigh checkweigher range

Checkweighers are usually positioned at the end of the packaging line to do a final check on individual product or package weight. But Thermo’s range of VersaWeigh checkweighers can also be used in the production process to control products that are volumetrically dosed, reducing the amount of giveaway.

Suitable for packages up to 25 kg, the checkweighers can also be integrated with the Apex metal detector. They are available from JL Lennard.

With large, easy-to-read colour touch-screen operation, the checkweighers use Windows XP and have configurable security access levels. Automatic set-up reduces the need for formal training, while contextual help-screens guide operation.

A SmartZone display offers a snapshot of product information on the main screen, a bright ‘good/bad’ indicator, as well as a large, high-visibility weight display. Users can also access detailed views of production line performance, including product giveaway. The checkweighers have 100 standard product memories that are expandable and searchable by product or name.

With few wearing parts, the checkweighers have full stainless-steel frames, electronics enclosures, conveyor beds and high-torque, sealed, brushless DC motors.

Rapid-release conveyor belts provide easy access for cleaning, while the trapezoid frame minimises bacteria traps. Rounded tube and cabinet surfaces help to avoid build-up of product.

The range includes dynamic broad spectrum vibration analysis and compensation (DBSVAC) that minimises ambient environmental influences to improve performance, while a modular weigh-engine approach enables integration into larger packaging systems.
