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.

PAV is a compact fixed-gain acoustic emission preamplifier for common AE sensor installations. It provides 40 dB gain, phantom power supply through the signal cable, AST function and a metal housing for electromagnetic shielding and mechanical protect

The GI150/5 is an intrinsically safe explosion-proof sensor, it is integrated with a 26dB5V preamplifier inside.

GH150 is a compact 150 kHz ultra-high temperature AE sensor with an extended 1–1.2 m metal tube and 2m cable for monitoring hot metallic structures up to 600°C.

GH150/1 is a compact 150kHz high temperature AE sensor with an extended 0.5m metal tube and 2m cable for monitoring hot metallic structures up to 350°C.

GH150 (Magnetic) is a 260 kHz ultra-high temperature acoustic emission sensor for monitoring up to 600°C, featuring stainless Invar steel contact surfaces, IP68 protection, 20cm heat-resistant metal tube and 3m integral BNC cable.

GH150/1 (Magnetic) is a 170 kHz high temperature acoustic emission sensor for monitoring up to 350°C, featuring stainless/Invar metal contact surfaces, IP68 protection, integral BNC cable and magnetic or clamp mounting.

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