checkweigherprovides the highest quality. It is applied mainly for pharmaceutical and food industry. Used magnetoelectric modules allow to weigh products quickly, providing the highest accuracy of weighment. The device features a friendly, intuitive interface and several built-in functions that enable the statistical data operation and service process.
Checkweigher allows a precise control of packaged products in accordance with the valid regulations. A modular base construction allows a flexible configuration of the device.
Complex communication modules fully integrate the
scaleswith the production line, which makes automatic operation of the line possible. Connecting the
checkweigherto the computer system allows to monitor production process on-line, save the weighments, generate the reports considering the
weighingstatistics, quantitative statistics and the production line failures and stoppages.
DWM automatic checkweigher series is designed to control single products with
massnot greater than 7500 g. Scale software enables setting the parameters according to customers regulations or according to the current regulation on Control of Packaged Goods. The flexible limits working mode was designed for pharmaceutical concerns. DWM automatic
scalesseries is attested by NIH.
Main applications :
· Control of goods in accordance with regulation on Control of Packaged Goods,
· Full control of production process,
· Control over dozing devices,
· Control over the products packaging precision,
· Weighing medicines, blister packs, syrups, etc.

The checkweigher features an industrial computer and Windows Embedded operating system. This solution allows an intuitive and easy cooperation with the device. The scale and standard office interface are similar, which facilitates the operation.
Database module was designed on the basis of Microsoft SQL Server, which allows a stable and safe saving of data generated by the scale, as well as an easy connection of the database with the client’s software. Saving the databases and weighment records on two separate memory carriers provides high security.
All checkweigher elements like drives, rejectors, emergency buttons, warning lights are controlled by the real time controller, which guarantees the flow of work and an instant reaction to the emergency signals.
Checkweighers provide the full exchange of data via Ethernet network. The communication protocol ensures the automatic transfer of weighment records, databases update, introduction of new settings and the device work monitoring in on-line mode.
Compliance with 21 CFR Part 11.
The following functions are available to ensure compliance with the regulation:
- 10 permission levels for operators to be defined by the administrator,
- requirements for each operator's passwords (determined by the administrator: minimum length, upper-case letters and digits quantity, special signs quantity),
- the requirement to enter new password at first logging (the first password is entered by the administrator creating the account),
- determination of password validity period in days
- automatic logout after a specified time of inactivity
- operator lockout after 3 incorrect login operations; lockout time specified,
- unlimited account lockout after 6 incorrect login operations; the account can be unlocked by the administrator
- saving changes to Audit Trail file; detailed reports on all modifications carried out on the checkweigher (information on parameters modifications including previous and new values), adding information about modification reason. This applies to all operational parameters of the checkweigher, e.g. conveyors speed, enabling/disabling ejector, ejector settings modification, checkweigher start/stop, logging and data contained in all products, operators, weighings and reports databases. All login, start, stop operations and report generating are recorded.
