Flange Gap Monitoring System_Shenzhen Qianhai IntelliUnion Technology Development Co., Lt

Flange Gap Monitoring System

Wind turbine flange gap monitoring uses sensors on two flange faces to capture minute separation changes in real time. When the gap exceeds the allowable value, alarms prompt site inspection, preventing bolt fracture and resulting tower collapse.

Monitors gap changes at turbine flanges, including blades and towers, in real time and provides professional analytical and diagnostic plots. Configuration is flexible to meet customer requirements. The system is easy to use, accurate, stable, convenient to install and practical.

Monitoring Challenges

Missing Monitoring at Critical Locations Delays Risk Detection

Blade and tower flange connections lack effective online monitoring. Manual inspections cannot provide uninterrupted 24/7 coverage or capture minute gap changes, failing to reflect structural loads and real-time conditions and delaying risk detection.

Insufficient Professional Analysis Leads to Inaccurate Risk Assessment

Without systematic acquisition and specialist tools, gap curves, historical comparisons, time-/frequency-domain analysis and structural health assessments are unavailable. Experience alone cannot reliably identify loose bolts, flange deformation or abnormal stress, leaving O&M decisions without data support.

Poor Environmental Adaptability and Difficult Deployment and Use

Complex vibration, temperature extremes, wind and sand demand high reliability. Traditional devices offer inadequate protection, cumbersome wiring, complex installation and unintuitive interfaces, making them difficult to use and limiting practicality and stability.

Product Advantages

Real-Time Monitoring Across Locations for Comprehensive Structural Awareness

Covers critical blade and tower flange connections, continuously acquiring minute gap changes 24/7. Accurate data reflects connection loads and real-time condition, detecting emerging risks at their source.

Professional Analysis and Diagnosis

Provides gap-change curves, historical comparisons, time-/frequency-domain analysis and structural health assessment plots to help identify bolt loosening, flange deformation and abnormal stress.

Stable, Reliable and Easy to Use

Highly protected sensors withstand complex vibration, temperature extremes, wind and sand. Convenient installation without complicated wiring and an intuitive interface simplify use by O&M personnel.
