WM500/1 is a passive piezoelectric wideband miniature AE sensor. It is specially designed to provide a flat frequency response to acoustic emission signals over its entire frequency bandwidth.

The WI800 broadband built-in preamplifier integrated acoustic emission sensor has a frequency range of 50KHz-800KHz and a resonant frequency of 600KHz.

GI10 is a passive piezoelectric AE sensor with preamplifier built-in and very low frequency response, all-metal shell features makes it reliable and could be buried in the ground for long-term monitoring.

GI40 is a passive piezoelectric acoustic emission sensor with built-in 40dB28V preamplifier. And 15kHz-70kHz bandwidth makes it suitable for detecting low frequency acoustic emission signals.

The GI80 is a passive piezoelectric AE sensor with built-in 40dB28V preamplifier. And 20kHz-180kHz bandwidth makes it suitable for detecting low frequency acoustic emission signals.

GI150 is a narrowband integrated AE sensor with built-in 40dB28V preamplifier. Stainless steel material makes it reliable and endurable and its 60 kHz-400 kHz bandwidth covering the frequency range of most AE applications.

The WI800/1 broadband built-in preamplifier integrated acoustic emission sensor has a frequency range of 50KHz-800KHz and a resonant frequency of 600KHz.

The voltage signal output by acoustic emission sensors can sometimes be as low as a few microvolts. Such weak signals, if transmitted over long distances, will inevitably decrease in strength. The original sensor signal needs to be amplified several t
