ACOUSTIC WAVE (ACOUSTIC EMISSION) SENSORS

Acoustic wave (acoustic emission) sensors are the ceramic piezoelectric transducers converting the mechanical elastic waves to electrical signals. AE sensors are used to test storage tanks, heat exchangers, piping, reactors, aerial lift devices, as well as gas, petro-chemical and nuclear power plants.

We develop and manufacture various types of AE sensors, including general purpose type, Wide-band type, Integral Preamplifier type, Intrinsically Safe type, High Temperature type, miniature type, as well as customized acoustic emission sensors.

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 AE sensors (narrower band but high sensitivity).
Resonant narrow-band acoustic emission 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.
