MT-DZ-XL-S2-01 High-Speed Leak Detection System Enhances Packaging Quality Control for Modern Production Lines

Advanced DSP-Based Pressure Inspection Technology Supports Up to 300 Packs per Minute

As packaging manufacturers continue to demand higher efficiency and stricter quality standards, automated leak detection technology has become an essential part of modern production lines. The MT-DZ-XL-S2-01 automatic leak detection system has been developed to address this growing need, delivering high-speed, high-precision inspection for liquid and gas-filled packaging products.

Designed for continuous industrial operation, the MT-DZ-XL-S2-01 combines advanced belt-compression sensing technology with proprietary DSP digital signal processing algorithms to provide reliable online pressure testing at speeds exceeding 300 packages per minute.

High-Speed Online Leak Detection for Flexible Packaging

The MT-DZ-XL-S2-01 adopts a contact-based inspection method that directly measures internal pressure changes inside product packaging. During operation, products pass through a specially designed belt-clamping mechanism that applies controlled pressure to the package surface.

A side-mounted force sensor captures the resulting pressure response and converts it into digital signals for real-time analysis. The system’s intelligent DSP processing technology accurately identifies abnormal pressure variations caused by leakage, insufficient sealing, or package deformation.

Compared with traditional inspection methods, the system offers more stable sampling performance and improved detection accuracy, making it suitable for demanding high-speed production environments.

Suitable for Multiple Packaging Applications

The inspection system is designed for a wide range of flexible packaging products, including:

• Liquid nitrogen-filled cartons and bags

• Steam-filled or gas-filled plastic pouches

• Liquid aluminum foil stand-up pouches

Its dual-pressure inspection capability allows the machine to accommodate both high-pressure and low-pressure packaging products across different industries.

Innovative Pre-Compression Leak Detection Technology

One of the key innovations of the MT-DZ-XL-S2-01 is its front-end guide and pre-compression mechanism.

Before entering the main inspection area, the product is gently pre-extruded to stabilize internal pressure. If leakage exists, the system releases pressure as completely as possible and performs pressure measurement again at the rear inspection section.

Packages with proper sealing maintain relatively stable pressure values, while leaking or poorly sealed products show significant pressure deviation. This comparison-based detection method significantly improves leak identification reliability and reduces false rejection rates.

Intelligent Real-Time Monitoring and Automatic Rejection

The system integrates intelligent conveyor synchronization technology that automatically adjusts to production line speed. During line stoppages, the machine automatically pauses operation to prevent package damage or conveyor blockage.

Inspection results are displayed in real time through a user-friendly HMI interface, allowing operators to monitor dynamic rejection data and system status continuously.

When defective products are identified, the control unit immediately activates the rejection mechanism to remove non-conforming packages from the production line automatically.

Additional features include:

• Pressure detection accuracy within ±0.02 MPa

• High-speed vibration and impact resistance

• Visual alarm indication system

• Continuous automatic rejection function

• Shutdown protection system

• Fully localized Chinese-language operation interface

• 24/7 remote technical support capability

Designed for Industrial Reliability and Safety

Constructed with an integrated 304 stainless steel frame, the MT-DZ-XL-S2-01 is built for durability in industrial production environments. The equipment supports single-phase AC 220V power input with low energy consumption of approximately 250W.

For optimal performance, the system is recommended for installation on a straight conveyor section
