Challenge

Service facilities required a specialized, mobile station capable of performing precise airflow calibration for engine bearing compartments. The device had to strictly meet the engine manufacturer’s rigorous technical requirements, support both positive pressure and vacuum modes, and handle multiple measurement ranges across different connection configurations.

Solution

Proximo designed and engineered the Multi Range Airflow Calibration Cart. This highly versatile, mobile station enables accurate detection and measurement of leaks within engine bearing compartments under variable pressure conditions. The system features four distinct, selectable calibration modes and an intuitive touchscreen control interface.

Scope of Work

Comprehensive engineering and manufacturing services:

• Mechanical design and manufacturing of the mobile calibration cart structure
• Development of the pneumatic system supporting positive pressure and vacuum modes
• Integration of multi-range instrumentation for precise airflow and leak measurements
• Programming and deployment of the touch panel control interface for data visualization
• Calibration system adjustment to align with specific engine manufacturer standards

Outcome

The service facilities received an OEM-compliant, fully integrated diagnostic tool. The combination of advanced multi-mode calibration loops and an ergonomic touch-panel interface significantly streamlined the inspection process, ensuring accurate validation of engine bearing compartment integrity.
