… that makes your processes legal for trade:DWS2103 - The digital weighing system …

The DWS2103 digital scale display is used for communication between digital load cells and AED... transducer

electronics. This combination enables legal-for-trade, automatic scales for automatic weighing instruments

(AWI) to be implemented, e.g. for automatic catch weighers, automatic checkweighers and automatic

gravimetric filling instruments.

Demonstrably exclude manipulationsThe EC directive MID (Measuring Instruments Directive) requires data transmission that excludes any form of

manipulation. The DWS2103 digital scale display guarantees, even in legal-for-trade mode, secure encrypted

transmission of measurement data from the load cell to the evaluation electronics (256 bit encryption technology).

100% data security is therefore guaranteed at all times.

Use the advantages of fully digital signal transmissionDigital signal transmission offers numerous possibilities for new concepts. This includes data transmission via WLAN or

voltage supply via self-contained systems such as e.g. solar, fuel cells or rechargeable batteries. Wireless transmission

also offers e.g. the advantage of galvanic isolation. The DWS2103 also does not have to be installed in the direct vicinity

of the actual scale and it is also possible to operate several scales simultaneously with just one display. Digital technology

also enables entry into asset management for weighing applications, as information can be read out from the sensor.

Achieve digital precision - even for existing analog systemsIncidentally: You do not need to replace all analog load cells immediately if you want to use the DWS2103. Digitize the

signals of analog load cells using the AED product family. So that you can profit from digital precision and freedom of

data exchange even with existing systems.
