Metal structure inspection acoustic emission sensor GH150/2

for predictive maintenancefor process monitoringfor pipes

Product overview
GH150/2 is a narrowband high-temperature acoustic emission (AE) sensor with a 150 kHz resonant frequency and usable bandwidth from 60 kHz to 400 kHz. It is designed for structural health monitoring and NDT in industrial environments up to 170°C. The sensor features a SUS-304 stainless steel housing, a ceramic sensing face and an integral 1.5 m high-temperature cable terminated by a BNC connector.

Features

• Resonant frequency: 150 kHz
• Frequency range: 60 kHz – 400 kHz
• Sensitivity (peak): >73 dB (Ref V/(m/s))
• Operating temperature: -20 to 170°C
• Protection: IP68
• Face material: ceramic
• Housing: SUS-304 stainless steel
• Integral high-temperature cable: 1.5 m with BNC connector (side)
• Compact size: 19×15 mm (DxH); weight: ~45 g

When to use GH150/2

• AE monitoring of pipelines, pressure vessels and storage tanks in process plants
• Long-term structural health monitoring in moderately high-temperature zones
• Offshore platform structural monitoring where equipment temperatures reach up to 170°C
• High-temperature metal component inspection requiring 150 kHz detection
• Applications needing a compact sensor with an integral high-temperature cable

Limitations
GH150/2 is not recommended for continuous exposure above 170°C. For higher temperatures select a higher-temperature AE sensor or use a waveguide-based installation. In environments with strong low-frequency vibration, heavy flow noise or long propagation distances, consider attenuation, background noise and material coupling when selecting the sensor.

Installation Notes

• Clean and prepare the mounting surface before installation
• Use a high-temperature couplant suited to the actual surface temperature
• Ensure stable contact and appropriate hold-down pressure on the sensor face
• Avoid cable tension, sharp bends and direct mechanical impact on the integral cable
• Verify channel response and sensor coupling before testing or long-term monitoring

Applications

• Pipeline AE monitoring
• Pressure vessel testing
• Storage tank inspection
• Offshore platform structural monitoring
• Plant equipment condition monitoring
• High-temperature structural health monitoring

Compatible accessories

• Preamplifiers: PAS / PAV
