Low-resonant frequency acoustic emission sensor G40

for grinding machinesfor composite and concrete structure inspectionfor corrosion detection

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. Features： Stainless steel case and ceramic interface, M5 connector. Rugged design, stable performance, good compatibility. G40 is a passive piezoelectric acoustic emission sensor. The low frequency response makes it suitable for monitoring conditions of large objects like concrete, steel structures and geologic structures. It also could be used for monitoring leakage and corrosion of pressure vessels or valves and for detecting partial discharge.
