83matic Evaluation Unit – Flexible Weighing Electronics for AWI & AWE Applications

The 83matic evaluation unit is a high-performance, versatile, and practical solution for automatic scales in applications subject to legal metrology. It is certifiable as an automatic scale (AWI and AWE) and approved according to OIML R 61 as well as OIML R 51. This makes the device ideal for legal-for-trade use in certified goods transactions, e.g., in automatic filling, checkweighing, and conveyor systems. The robust stainless steel housing, high user-friendliness, and extensive interfaces and software functions make the 83matic a reliable weighing electronic system for industry, logistics, and production.

Certified Quality & Robust Construction

The 83matic is AWI and AWE approved and meets all requirements for measurement accuracy, tamper resistance, and traceability of calibration-relevant weighing data.
The durable stainless steel housing (1.4301 chrome-nickel steel) with IP65 protection class reliably protects against dust, moisture, and aggressive environmental conditions. With an intrinsic weight of approx. 2.8 kg, the device is both stable and flexibly integrable.

Flexible Mounting & Clear Display

The evaluation unit can be mounted as a tabletop unit, wall-mounted unit, or stand-mounted unit and adapts optimally to existing systems.
The main display features a 7-digit, backlit 14-segment LCD with 27 mm digit height. It is complemented by a secondary display (2 × 20 character LCD) with 5.5 mm high, backlit characters for presenting additional information and process data.

Intuitive Operation & Durable Keyboard

The 34-key membrane keyboard with alphanumeric input enables fast and secure operation. It is particularly resistant to aggressive substances and therefore suitable for continuous use in industrial environments.

Extensive Connectivity & Load Cell Connection

For integration into automation and IT systems, the 83matic offers modern interfaces:

• 2 × RS-232

• USB-Device

• USB-Host

• Ethernet (LAN)

The load cell connection with one measuring input supports:

• up to 10 load cells of 350 Ω each

• or up to 30 load cells of 1100 Ω each
  The supply voltage of 12 VDC ensures stable and precise measuring operation.

Powerful Memory Functions for Processes Subject to Legal Metrology

The 83matic is equipped with extensive memory functions that are specifically designed for certifiable AWI and AWE applications:

• Totalizer memory with up to 160 memory slots

• Alibi memory (AWE) with up to 6 million entries for legally compliant archiving

• Database for up to 1000 data records

• Tare memory and fixed value memory for quick parameterization

A battery-backed real-time clock with a service life of approx. 10 years ensures complete documentation of all calibration-relevant weighings.

High-Performance Software & Automation Functions

The integrated software supports numerous functions for operation subject to legal metrology:

• Summing and counting

• Automatic filling and dosing

• Price labeling

• Control and switching functions

• Individual print layouts

• Simple IT and ERP integration

• Alibi memory with variable data storage

Application Areas AWI – Certifiable Automatic Filling

As a certifiable AWI solution, the 83matic enables fast, precise, and reproducible filling:

• Optimized control of coarse, medium, and fine feed

• Acceptance of all relevant control signals

• Adaptable weighing sequence

• Control of labeling systems possible

• High process reliability in filling plants subject to legal metrology

• Optimal for certifiable or certified big bag filling, sack filling, filling systems for bulk goods, filling of powders and fine materials, liquid filling by weight, dosing scales in production processes, and filling with labeling.

Application Areas AWE – Certifiable Individual Weight Recording

In AWE applications, the 83matic serves for the legally compliant recording of individual weights:

• Control of feed, weighing, and discharge conveyors

• Complete storage of all weighings in the alibi memory

• Processing signals from light barriers, scanners, and sensors

• Can be used in all common conveyor systems

• Ideal for checkweighers, logistics, and production processes

• Optimal for certifiable or certified checkweighers in packaging lines, individual weight recording in conveyor systems, logistics and distribution centers, production & quality assurance

Conclusion

The 83matic evaluation unit is a certifiable, robust, and versatile weighing electronic system for automatic scales (AWI & AWE). It combines legal compliance, precise measuring technology, extensive memory functions, and flexible system integration, making it the optimal solution for demanding, automated, and regulated industrial applications.
