Worry-free weighing

WHEN it developed its new line of analytical balances, Mettler Toledo added several technological features such as sensors, RFID, and more, to ensure error-free processes and full traceability. One of the new features is the StaticDetect? sensor technology, which automatically checks samples and containers as they are placed on the balance. It prevents electrostatic charge from interfering with weighing results. Influences from electrostatic charge are one of the biggest challenges in analytical weighing. Through normal handling, samples and weighing containers can easily accumulate static, leading to difficulties in dosing and errors in weighing results. With high electrostatic influences, it may not even be possible to get a stable reading on the balance. When a container or sample is placed on the balance, StaticDetect measures the weighing error attributable to electrostatic charge and gives a warning if the process tolerance limit is exceeded. Antistatic measures can then be employed. A compact point electrode accessory attaches to the side of the balance for convenient deionisation of charged samples and containers. For the highest process security, users can elect to block the release of the weighing result.

Green light signal

A StatusLight? indicator has been added to the balances as well. This seemingly simple feature tells users that the balance tests are up to date and that it is safe to start weighing. When balance calibration and routine tests are updated and the balance is level and performing correctly, the StatusLight clearly indicates with a (Enterprise Resource Planning) systems and MES (Manufacturing Execution Systems). With this comes a need for increased security measures to protect mission-critical data and operational parameters.”

The CDS leverages industry-standard IT infrastructure and protocols such as LDAP, SSL and HTTPS for state-of-the-art network security. For example, when a user logs into an In-Sight camera, his or her credentials are passed to CDS for authentication, and user-specific permissions are transferred back to the camera. The CDS can customise access permissions for each user, which helps to ensure the integrity of the vision system setup and production quality and safety. Access can be customised by job parameters, In-Sight camera settings, In-Sight Explorer maintenance functions, or other specifications.

The CDS, which completes the company’s software suite for managing the security of machine vision systems, complements existing products such as the Cognex Audit Message Server, which logs system parameter changes and user logins, and the TestRun? tool, which validates changes to application parameters.

Enterprise customers can utilise the CDS software to help protect sensitive information and to comply with industry regulations, such as 21 CFR Part 11compliance for validation. Many customers can also use CDS to manage large numbers of In-Sight vision systems across the factory, reducing setup and maintenance costs.
