DIS2116 – Easy to use and secure: DIS2116 for reliably determining weight on vehicle scales as well as railroad track scales

DIS2116 is the digital weighing system that enables your truck scales to comply with the latest requirements regarding security and efficiency.

Because DIS2116 features far exceed the functions of a purely digital display – they also enable all relevant characteristics (e.g. scale configuration, off-center load compensation, legal-for-trade modes, measurement signal filters) to be easily configured, at the same time providing maximum data security.

Easy operation of the weighing system is a must, especially when used on vehicle scales, truck scales and railroad track scales with many loading operations every day. Thanks to its intuitive control DIS2116 allows you to change all relevant settings very quickly. You benefit in particular from the time-saving, electronic off-center load compensation that is performed easily and very precisely at high reproducibility.

In addition, DIS2116 complies with the highest data security standards. Latest EC directives require manipulation-proof data transmission. In its legal-for-trade mode, the DIS2116 digital weighing system guarantees secure, encrypted data transmission.

The DIS2116 interfaces open up virtually all connection opportunities for integration of the scale electronics into other systems. An Anybus port for connection to Ethernet or other bus systems is available as an option.

Combined with the C16i load cell the DIS2116 operates as a purely digital measuring chain. You benefit from all advantages of secure, digital signal processing – for example, signal quality, tested EMC and dynamics without data loss. One DIS2116 allows configuration of vehicle scales with up to three segments, each with maximal eight load cells. The VKD2R-8 digital junction box is used for connecting the load cells in parallel.

* For connecting digital load cells
* Alibi memory for printed data and configuration
* Encrypted data transmission between load cell and DIS2116
* COM port for a printer (RS-232 or USB)

DWS2103 scale display – Product preview: Digital technology opens up completely new opportunities

The DWS2103 is a digital scale display for communication with legal-for-trade load cells and electronics. Combined with the AED digital transducer family or FIT® digital load cells it enables legal-for-trade, automatic weighing instruments (AWI) to be implemented, for example, automatic catch weighers, automatic checkweighers, and automatic gravimetric filling instruments.

Manipulation impossible

The DWS2103 meets the maximum requirements in terms of security. The latest MID EC directive (Measuring Instruments Directive requires data transmission that excludes manipulation. In legal-for-trade mode, the DWS2103 digital scale display guarantees secure, encrypted transmission of measurement data. Consequently, legal-for-trade capability is fully guaranteed at any time.

Benefits of digital signal transmission

Purely digital signal transmission opens up opportunities for new concepts. These include WLAN data transmission or voltage supply by self-contained systems, for example solar, fuel cells or rechargeable batteries. Wireless transmission offers more advantages, such as galvanic isolation. In addition, the DWS2103 needs not be installed in close proximity to the actual weighing instrument; multiple scales can be operated simultaneously using a single display. Moreover, digital technology enables asset management of weighing applications to be implemented, because information about the sensor can be read out.

Fully digital measuring chain

Combined with FIT® load cells or the AED digital transducers, HBM is the only manufacturer worldwide to offer a digital solution ranging from components to complete solutions, i.e. the complete, purely digital measuring chain.

Also for use with analog systems

Incidentally: You need not replace all analog load cells, if you want to use the DWS2103. Digitize the signals of analog load cells using the AED product family. This enables you to continue using your systems and, at the same time, benefit from digital precision.

AES encryption technology
