The G80/1 is a passive piezoelectric AE sensor with narrowband. High protecting grade makes it possible to work in the water or uderground.

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.

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.

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.

Passive piezoelectric miniature AE sensor. The connector was designed on the side of the sensor and the small size makes it possible to work in narrow space.

Passive piezoelectric miniature AE sensor. The connector was designed on the top of the sensor and the small size makes it possible to work in narrow space.

Passive piezoelectric AE sensor with built-in 34dB 12V 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.
