Narrowband integrated sensor with built-in 40dB 28V preamplifier. Stainless steel material makes it reliable and endurable and its 60 kHz-400 kHz bandwidth covering the frequency range of most AE applications.

GD40 is a differential waterproof narrow band sensor with 1.7 meters cable, it is suitable for working in noisy environment, could effectively suppress the common-mode noise.

The GD150 is a differential waterproof narrow band sensor with 2.2 meters cable, it is suitable for working in noisy environment, could effectively suppress the common-mode noise.

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 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.

Sensor hold-downs is mainly for holding the sensor on ferromagnetic materials, basically composed of permanent magnet and shell.

The LS 5VDC is an intrinsically safe explosion-proof AE sensor with build-in 26dB5V preamplifier. It's well suited for detecting leakege and corrosion in harsh environment that requires intrinsic safety and for structures health monitoring.

GH150/2 is a medium high temperature acoustic emission sensor with 1.5 meters high temperature resistant cable, could be used in high temperature environment ( up to 170 ℃ ).
