QAWRUMS G150/1 Piezoelectric AE Sensor, >75dB, 150 kHz, IP68, SUS-304 Stainless Steel, Ceramic Face, BNC Connector

No, the G150/1 is a passive piezoelectric sensor without an integrated preamplifier. It requires an external AE preamplifier or a data acquisition system with high-impedance, low-noise input conditioning to amplify its raw signal before analysis. This design preserves signal fidelity and allows flexibility in system gain staging.

For optimal acoustic coupling, mount the sensor directly onto the test structure using a thin layer of couplant (grease or gel) and secure it with a magnetic hold-down, adhesive, or mechanical clamp. The flat ceramic face must maintain full, uniform contact with the surface to ensure efficient transmission of acoustic emission waves into the sensing element.

Yes, the G150/1 features an IP68 waterproof rating and a SUS-304 stainless steel housing, making it suitable for submerged deployment or use in high-humidity industrial environments. Ensure the BNC connector and cable termination are properly sealed according to your system's requirements for long-term reliability.

The sensor is compatible with any AE monitoring system or general-purpose data acquisition unit that provides a high-impedance (>10 MΩ) analog input channel with BNC connectivity. The signal typically requires 40-60 dB of external gain via a preamplifier before being digitized for crack localization, feature extraction, and waveform analysis.
