ACOUSTIC EMISSION SENSORS
What are acoustic emission sensors and how do they work?
Acoustic wave (acoustic emission) sensors are the ceramic piezoelectric transducers converting the mechanical elastic acoustic waves generated in the material (e.g. elastic waves occur when a material cracks, wears, deforms, or corrodes) to electrical signals. The electrical signals are then amplified and filtered by a preamplifier and then transmitted to a special acoustic emission acquisition instrument for further data processing and analysis.
We develop and manufacture various types of acoustic emission sensors for sale, 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 tailored to meet the special needs of our customers and a wide range of applications.
Please see categories of acoustic emission sensors below for further information.
