Frequently Asked Questions
What is automated leak detection?
Automated leak detection is the process of using machines and sensors to identify leaks in components or systems without manual inspection. Our systems use pressure decay testing, which measures pressure changes over time to detect even the smallest leaks with precision.
How does pressure decay leak detection work?
Pressure decay testing works by pressurising a sealed part, then isolating it and monitoring the pressure over a set period. A drop in pressure indicates a leak. It’s a reliable, non-destructive method used widely in automotive, medical, and industrial applications.
What are the benefits of automated leak detection?
- Higher Accuracy: Detects micro-leaks with minimal false positives
- Repeatability: Consistent results across every test cycle
- Improved Safety: Reduces operator handling of hazardous or sensitive components
- Faster Testing: Increases throughput in production environments
- Data Logging: Supports traceability and compliance
- Lower Costs: Reduces rework, product recalls, and quality failures
What industries use ALPHR’s automated leak detection systems?
Our solutions are used across:
- Automotive: Brakes, fuel systems, oil pumps, headlights
- Medical: Inhalers, syringes, sealed enclosures
- HVAC & White Goods: Boilers, valves, heat exchangers
- Defence & Industrial Manufacturing: Castings, solenoids, mission-critical components
Can automated leak detection be integrated into existing lines?
Yes. ALPHR offers modular systems that can be installed as standalone test stations or fully integrated into rotary tables, palletised lines, or robotic cells. Systems are available in manual, semi-automated, or fully automated configurations depending on your needs.
