Acoustic Emission Sensor Model List and Selection Table
Compare AE sensors by frequency, sensitivity, temperature, preamplifier type and application
QAWRUMS provides a complete acoustic emission sensor model list to help engineers compare and select AE sensors for different testing and monitoring applications. This selection table includes general-purpose AE sensors, integral preamplifier sensors, broadband sensors, high-temperature sensors, miniature sensors, differential sensors, intrinsically safe sensors, and customized acoustic emission sensors.
You can compare each model by resonant frequency, frequency range, sensitivity, preamplifier type, size, weight, operating temperature, protection grade, connector type, mounting method, cable model, and typical applications. These AE sensors are used for crack detection, leakage monitoring, corrosion diagnosis, partial discharge detection, composite material testing, pressure vessels, pipelines, tanks, valves, bridges, rotating equipment, and long-term structural health monitoring.
AE Sensor Selection Guide
For most metallic structures such as pressure vessels, storage tanks, pipelines, and steel components, resonant AE sensors around 150 kHz are commonly used because they provide high sensitivity and good signal-to-noise (SNR) ratio for crack growth and active damage detection.
For low-frequency applications such as leakage detection, corrosion activity, partial discharge, rock testing, or buried pipeline monitoring, 10 kHz, 40 kHz, or 80 kHz AE sensors may be more suitable depending on signal attenuation and background noise.
For waveform analysis, frequency spectrum research, composite materials, or applications where the source frequency is unknown, broadband AE sensors are recommended because they provide a wider frequency response.
For harsh environments, choose high-temperature, intrinsically safe, waterproof, differential, or miniature AE sensors according to the installation conditions, operating temperature, cable length, noise level, and safety requirements.
If you are not sure which model to choose, please contact us with your material, structure type, expected AE source, temperature, installation method, and acquisition system. Our technical team can recommend suitable AE sensors for your application.

Notes for Waterproof and Customized AE Sensors:
1. For SMA connector models, the protection grade can be upgraded depending on the cable and sealing design. Waterproof cable assembly is required for waterproof applications.
2. Standard waterproof AE sensors are generally designed for fresh water at room temperature. For seawater, salt lake water, corrosive liquids, or long-term underwater use at elevated temperatures, please contact us for a customized sealing and material solution.
3. Sensor sensitivity, frequency response, cable length, connector type, mounting accessories, and temperature resistance can be customized according to application requirements.

FAQ:
1) How do I choose an acoustic emission sensor?
Choose an AE sensor based on material type, expected AE source (cracks, friction, leaks, corrosion etc.), 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 AE sensors are commonly used because they provide high sensitivity and good signal-to-noise ratio for crack detection and structural monitoring.
3) When should I use a broadband AE sensor?
Broadband AE sensors are recommended for waveform analysis, frequency spectrum research, composite materials, and applications where the AE source frequency is unknown.
4) When should I use an integral preamplifier AE sensor?
Integral preamplifier AE sensors are useful when installation space, cable length, field noise, or simplified wiring are important considerations.
5) Can AE sensors be customized?
Yes. AE sensors can be customized for frequency response, sensitivity, temperature resistance, size, connector type, cable length, waterproofing, and special installation requirements.
6) Are AE sensors compatible with different acquisition systems?
Most AE sensors can be used with standard acoustic emission acquisition systems (Qawrums (Qingcheng / Soundwel) / Mistras (Physical Acoustics) / Vallen ) if the connector, preamplifier, power supply, impedance, and signal input requirements are compatible.
