The AD11 from Air Leak Control is designed for in-line integration in high-speed production environments and provides rapid, accurate and repeatable quality control.

Main features

• Very high-resolution differential pressure sensors for stable measurement and reduced thermal and pneumatic disturbance effects.
• Extremely short cycle times to prevent quality control from becoming a production bottleneck.
• Advanced test algorithms offering high repeatability and flexible test configuration.
• Compact format for easy mounting on test benches and production integration.
• Connectivity and control included: integrated relay board for PLC interfacing, RS232 link for communication and traceability, 24 V output and configurable pneumatic output for valve and accessory control.
• Modular design for durability and simplified maintenance.

Maintenance and Accessories

• Recommended maintenance: annual check and servicing of pneumatic components.
• Annual calibration required for certified accuracy.
• Optional accessories: remote control (2‑button, 4‑button or multifunction), internal/external fitting adapters, reference leak, remote display, trigger.

Industry sectors (example applications)

• Plastics & Polymers: plastic bottles, containers, piping and bottle caps.
