QingCheng develops and produces various and complete series of acoustic emission sensors to meet different application demands of acoustic emission non-destructive testing.
Typical Application Selection:
In terms of acoustic emission applications, most actual applications are on the stable metallic structure, for example: pressure vessels. The anisotropy of this type of material is relatively small, as well as the attenuation coefficient of acoustic wave. The frequency band range is between 25kHz ~ 750kHz. It is suitable to choose resonant sensors (narrower band but high sensitivity).
Resonant narrow-band sensors with the centre frequency of 150kHz are widely used for testing acoustic emission signals in engineering materials, which are under the condition of metallic material and other applications.
Resonant narrow-band sensors have high sensitivity and SNR, which are inexpensive, and have various specifications. On the occasion of knowing the basic characteristics of sound source propagation, if customers who want to acquire the acoustic signals in a certain frequency range, or to enhance the systematic sensitivity, it is better to choose appropriate resonant sensors, for example, sound localization.
It should be pointed out that the so-called resonant narrow-band sensor is not only sensitive to a certain frequency signal, but to a certain frequency band. But the signal sensitivity is lower for other frequency bands.

Note:
1.If the connector type is SMA, the protection grade can be upgraded to IP67. In that case, the cable must be water-proof. When connecting, it needs to rotate the sensor itself. The connector and the cable are integrated.
2.The water-proof sensors (either separated or integrated) are used in fresh water at room temperature. If there are salt lake water corrodes and sea water corrodes, or it requires to use in water at room temperature and above (80~170℃) for a long time, please contact us to solve the problem with composite material, which might increase the cost.
