The G150/1 is a passive piezoelectric AE sensor with narrowband and high sensitivity, also it is waterproof. Stainless steel material makes it reliable and endurable.

G150/2 is a passive piezoelectric all-metal AE sensor with narrowband and high sensitivity, also it is waterproof. Pure metal structure makes it reliable and endurable.

GI10/1 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.

GI35 is a passive piezoelectric AE sensor with built-in 40dB28V preamplifier. And 15kHz-70kHz bandwidth makes it suitable for detecting low frequency acoustic emission signals.

Passive piezoelectric AE sensor with built-in 26dB 5V preamplifier. And 15kHz-70kHz bandwidth makes it suitable for detecting low frequency acoustic emission signals.

Passive piezoelectric AE sensor with built-in 34dB 12V preamplifier. And 15kHz-70kHz bandwidth makes it suitable for detecting low frequency acoustic emission signals.

GI40/2 is a passive piezoelectric AE sensor, waterproof and all-metal shell features make it possible to be buried in the ground or work in the liquid for long-term monitoring.

Narrowband integrated sensor with built-in 40dB28V preamplifier. Its smaller than GI150 and its 60 kHz-400 kHz bandwidth covering the frequency range of most AE applications.
