QAWRUMS | Acoustic Emission Sensor Model List Selection Guide and Technical Comparison Frequently Asked Questions 1. How do I choose an acoustic emission sensor? Choose according to material, expected AE source, frequency range, sensitivity, operating temperature, installation space, background noise and acquisition-system compatibility. 2. What is the most commonly used AE sensor frequency? For many metallic structures, 150 kHz resonant sensors are commonly used because they provide high sensitivity and good signal-to-noise performance for crack detection and structural monitoring. 3. When should...
