Wide-band acoustic sensor WI500

for composite and concrete structure inspectionmonitoringpiezoelectric

WI500 is a passive piezoelectric acoustic emission sensor with wideband and preamplifier built-in. It is specially designed to provide a flat frequency response to acoustic emission signals over its entire frequency bandwidth. Features： Passive piezoelectric sensor with preamplifier built-in, stainless steel case and ceramic interface. WI500 is a passive piezoelectric acoustic emission sensor with integrated preamplifier, it does not need to be connected to the additional preamplifier, thus simplifying the wiring work. It is well suited for laboratory studying of surface displacement of structures due to different AE modes.It also could be used in applications requiring frequency analysis and composites research. It could be easily mounted with a magnetic hold-down.
