Evaluation unit 83matic for automatic weighing systems SWA & SWE

83matic evaluation unit – Flexible weighing electronics for SWA & SWE applications

The 83matic evaluation unit is a powerful, versatile, and practical solution for automatic weighing systems in legally regulated applications. It is legal for trade as an automatic weighing system (SWA and SWE) and approved according to OIML R 61 and OIML R 51. This makes the device ideal for legally compliant use in calibrated goods handling , e.g., in automatic filling, checkweighing, and conveyor systems. The robust stainless steel housing, high user-friendliness, and comprehensive interfaces and software functions make the 83matic a reliable weighing electronics solution for industry, logistics, and production.

Certified quality & robust construction

The 83matic is SWA and SWE approved and meets all requirements for measurement accuracy , tamper protection and traceability of calibration-relevant weighing data .
The robust stainless steel housing made of 1.4301 chrome-nickel steel with IP65 protection reliably protects against dust, moisture, and harsh environmental conditions. Weighing approximately 2.8 kg , the device is stable yet easily integrated.

Flexible mounting & clear display

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

Intuitive operation & durable keyboard

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

Extensive connectivity & load cell connection

The 83matic offers modern interfaces for integration into automation and IT systems:

• 2 × RS-232

• USB device

• USB host

• Ethernet (LAN)

The load cell connection with one measuring input supports:

• up to 10 load cells at 350 Ω each

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

High-performance storage functions for legally regulated processes

The 83matic is equipped with extensive memory functions specifically designed for calibrated SWA and SWE applications :

• Total storage with up to 160 memory locations

• Alibi storage (SWE) with up to 6 million entries for legally compliant archiving

• Database for up to 1000 records

• Tare memory and read-only memory for fast parameterization

A battery-backed real-time clock with a lifespan of approximately 10 years ensures the complete documentation of all calibration-relevant weighings.

Powerful software & automation features

The integrated software supports numerous functions for legally required operations:

• Adding and counting

• Automatic filling and dosing

• Price labeling

• Control and switching functions

• Custom print images

• Simple IT and ERP integration

• Alibi storage with variable data storage
