40dB Acoustic Emission Testing Equipment PAI Preamplifier

The voltage signal output by the acoustic emission sensor is sometimes as low as a few microvolts. If such a weak signal is transmitted over a long distance, the intensity will inevitably decrease. The original sensor signal needs to be amplified several times and then transmitted. The commonly used amplification factor is 40dB, and then it is transmitted to the signal acquisition unit via a high-frequency coaxial cable. The preamplifier is an analog circuit, the input is the voltage signal output by the acoustic emission sensor, and the output is the amplified analog signal.
