AE Sensor: Acoustic Emission Testing

BII7230 Series AE Sensor: Wideband Detection

AE (acoustic emission) sensors with aperture Φ2 to Φ12.7mm detects wideband stress wave released by the structural (Macro or Micro) deformation: cracking, leaking, ageing under load, chemical reaction, temperature gradients, etc. AE sensors are used as contact sensors in air and liquids/water (immersion sensors) to detect AE sources up to 198°C (388°F), or as embedded AE sensors which are encapsulated in structures/materials for Structural Health Monitoring (SHM). Linear and planar phase arrays can be configured with these small-aperture AE sensors to position AE sources. When AE sensors are used in air, the couplant (water, gel, grease, oils, adhesives, and commercial couplant.) is a necessary material to provide efficient acoustic coupling between the sensor face and the piece under test (DUT). AE sensors with preamps can transmit signals over long cable without degrading signals up to 1000m. This feature presents a solution for long-distance health monitoring of a structure.
