Laumas RFID Weighing Tunnel – Smart Double-Control Quality Inspection System

RFID Weighing Tunnel by Laumas: A Smart Double-Control System for Production Quality

In modern bottling plants, quality inspection is no longer limited to checking whether a package contains the correct quantity. As production lines process thousands of products every hour, the challenge becomes ensuring precision, authenticity, and real-time data verification.

Laumas Analysis introduces an advanced approach by integrating electronic weighing technology with intelligent RFID identification systems, creating a highly efficient and accurate double-control process.

When weight data and RFID identification are verified simultaneously, production errors have very little room to exist.

The challenge from the wine bottling industry

In Italy, Autentico srl required the development of an automated movable RFID/NFC tunnel integrated with a weighing system and management software for a wine bottling plant.

The project involved much more than simply measuring weight.

The system needed to:

• Identify every product through RFID/NFC technology
• Detect missing products inside a box
• Reject incorrect or non-conforming items
• Operate reliably in dusty and wet industrial environments
• Respect strict space requirements with a maximum overall size of 60 cm

This demanded a precise combination of weighing technology, load cells, RFID systems, and real-time software processing.

Laumas RFID tunnel integrated with weighing technology

To develop the movable RFID tunnel solution, Laumas implemented a specialized weighing configuration.

ACN 150 kg weighing platform

The system uses an ACN 150 kg weighing platform with dimensions of 600 × 600 mm, designed to meet space limitations inside the production facility.

Its compact structure allows seamless integration into conveyor systems and restricted installation areas.

APL 200 kg single-point load cell

The platform incorporates an APL 200 kg load cell manufactured from aluminum alloy with IP65 protection.

This ensures:

• Dust resistance
• Water protection
• Stable operation in industrial environments

WDESK-L weight indicator

The WDESK-L weight indicator features IP67 protection, making it suitable for demanding production environments.

Its 20 mm backlit LCD display provides excellent visibility, allowing operators to monitor measurements and production status from a distance.

How the double-check system works

RFID identifies every individual product

Each product is equipped with a dedicated RFID/NFC transponder label.

These labels provide several important advantages:

• Impossible to clone
• Anti-counterfeit protection
• Global distribution tracking
• Supply chain monitoring capabilities

As products enter the RFID tunnel, the system scans every tag contained within the box.

Real-time weighing during conveyor movement

While RFID scans product information, the box simultaneously moves across the weighing platform integrated into the conveyor.

Weight information follows this processing chain:

Load Cell → WDESK-L Indicator → PLC → Management Software

The PLC then begins the verification process.

Automatic cross-checking of data

This is one of the most impressive aspects of the system.

The PLC compares:

• Number of products identified by RFID
• Actual measured weight
• Expected weight of a complete box

If the collected information does not match predefined parameters, the package is immediately identified as non-conpliant.

The conveyor system automatically rejects it from the production flow.

Even a box missing a single product can be identified almost instantly.

Flexible design for different production needs

One of the key strengths of the movable RFID tunnel is adaptability.

The machine was designed for versatility.

Easy relocation according to production demands

Unlike fixed inspection stations, the system can be relocated whenever production requirements change.

Manufacturers can move it to different production areas with minimal effort.

Compatible with multiple packaging types

The solution adapts easily to:

• Carton boxes
• Packaging containers
• Bottled products
• Various product dimensions

This flexibility makes it suitable for food processing, beverage production, logistics, and packaging industries.

Added value of the Laumas solution

Accurate dynamic weighing performance

The ACN 150 kg platform delivers reliable results even in dynamic weighing applications.

Products moving across conveyors can still be measured accurately.

High throughput up to 9000 bottles per hour

Thanks to the fast transmission speed of the WDESK-L indicator, production lines can reach capacities of up to 9000 bottles per hour.

This level of performance makes the system suitable for high-volume manufacturing environments.

Significant reduction in production errors

The combination of RFID verification and weight inspection helps:

• Reduce packaging errors
• Detect missing products
• Eliminate data inconsistencies
• Prevent counterfeiting
• Improve overall process reliability

Cost-effective and efficient implementation

An interesting aspect of the solution is its balance between performance and cost.

The combination of:

ACN 150 kg + APL 200 kg + WDESK-L

creates a highly efficient system specifically designed for compact conveyor and roller applications.

RFID and weighing technology are reshaping production management

In the past, quality inspection often depended on operators or isolated sensors. However, as production speeds continue increasing, even small delays can create significant operational issues.

Laumas adopted a smarter strategy by allowing multiple technologies to verify one another.

Instead of relying on a single source of information, RFID and weighing data continuously work together to ensure greater production accuracy.

This approach explains why integrated RFID and weighing systems are becoming increasingly important in smart manufacturing and industrial automation.
