Tracer gas leak detector LEAK-MASTER® ONE

CO2vacuumautomated

Overview
The LEAK-MASTER® ONE is an inline CO2 tracer-gas leak detector for one-by-one testing of individual MAP packages immediately after packaging. It combines micrometre-level leak sensitivity with high throughput by positioning packages individually in test chambers using pick-and-place robotics and subjecting them to a defined vacuum. Escaping CO2 through micro-leaks causes a measurable concentration rise detected by highly sensitive CO2 sensors.

Key features

• One-by-one testing of individual MAP packages
• Non-destructive detection of micro-leaks from ~10 µm (application-dependent)
• Twelve vacuum chambers operating in parallel
• Pick-and-place robotics for individual package handling
• Ultra-fast, highly sensitive CO2 sensors
• Up to 120 packages per minute (application-dependent)
• Standardised control and quality documentation via integrated PLC and touchscreen
• Stainless steel housing with acrylic upper doors

Benefits

• High-sensitivity individual-package testing using CO2 tracer gas
• Combination of high detection accuracy and high processing speed
• Detection of micro-leaks from approximately 10 µm depending on application conditions
• Targeted ejection/diversion of leaky packages via potential-free outputs
• Suitable for flexible and rigid packaging
• Multiple chamber inlays available for different formats
• Complete quality documentation and Ethernet data transfer
• Simple operation via integrated PLC with touchscreen

Operation and integration
The system requires packages with sufficient CO2 content (minimum recommended ~10% CO2). Each package is placed into an individual chamber where a defined vacuum is drawn. Any CO2 leaking into the chamber is measured by CO2 sensors and assigned to the corresponding package. Potential-free contacts provide signals to upstream/downstream equipment for alarms or pushers to reject faulty packages.

Options and accessories
Other models, chamber inlays, integration options and accessories are available on request.
