Couplant is required to use in between the sensor and the surface to be measured. The standard source of simulation is the pencil lead break signal.

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.

G10 is an ultra low frequency acousitc emission sensor with narrowband. And 1Hz -15kHz bandwidth makes it suitable for detecting very low frequency acoustic emission signals like geologic structure, leakage and corrosion.

The G40 is a passive piezoelectric AE sensor with narrowband. And 15kHz-70kHz bandwidth makes it suitable for detecting low frequency acoustic emission signals. It belongs to the low frequency sensor.

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.

G10/1 is an ultra low frequency AE sensor with narrowband. 1Hz -15kHz bandwidth makes it suitable for detectinglow frequency acoustic emission signals like geologic structure and leakage.

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.
