Vibration and Oscillation Monitoring
Contactless detection of mechanical vibrations and oscillatory motion for rotating and dynamic systems
The challenge
- Rotating machinery, motors, and mechanical structures often experience vibrations that, if undetected, can lead to wear, imbalance or failure
- Conventional sensors may lack the resolution, bandwidth, or durability required in high-speed, high-temperature environments
- Non-contact, real-time sensing is essential for monitoring critical components without interfering with their motion
- Specific rotating applications (e.g. turbines, compressors) require blade vibration analysis to prevent fatigue or damage
- Sensor systems must deliver stable, reliable readings under thermal, vibratory and EMI constraints
Our technical response
FOGALE Sensors provides advanced capacitive solutions for precise vibration and oscillation analysis, including in turbomachinery:
- Blade Tip Timing (BTT) systems for non-intrusive measurement of blade vibration in turbines and rotating machines
- Ultra-low noise electronics (e.g. MC925/MC935) designed to acquire vibration profiles with high temporal resolution
- Capacitive displacement sensors for axial and radial oscillation in shafts or mechanical structures
- High thermal and vibratory tolerance ensures reliability in harsh environments (e.g. engine test cells, compressors)
- Scalable systems for use in R&D, qualification test benches, or embedded monitoring
- Compatible with data acquisition platforms for frequency analysis, and fatigue monitoring
Proven applications
- Monitor vibrations and resonant behaviors without contact or added mass
- Analyze blade or component fatigue with high accuracy using Blade Tip Timing (BTT) systems
- Reduce unplanned shutdowns with early detection of abnormal oscillation or imbalance
- Integrate easily into rotating platforms, test benches or embedded control systems
- Ensure reliability with long-life, drift-free electronics and sensors
