Welcome to the AVT Acoustic Emission Sensor web site
been producing high quality Acoustic
Emission Sensors (AE Sensors) and Instrumentation for over 30 years. Acoustic Emission Technology is rapidly finding increased applications
across a broad spectrum of industries and our sensors meet the most stringent
demands, including use in hazardous areas where ATEX certification
are highly sensitive listening devices that form the vital link between
the structure or material under test and the analysis instrumentation.
emissions are stress waves produced by sudden structure changes in stressed
materials. The classic sources are defect-related deformation processes,
including plastic deformation and crack growth. AE sensors 'listen' for
the sound of failure occurring in materials and structures. Pressure
vessels, storage tanks, offshore rigs, heat exchangers, piping, reactors,
lift devices and nuclear power plants are just some of the
structures that can be monitored. Crack growth due to fatigue, stress
corrosion, hydrogen embrittlement and creep can be detected and located
using this technology.
is also highly effective in detecting and locating high pressure leaks,
monitoring product flow in pipes to detect the presence of contaminants
such as sand in crude oil and warning of blocked filters. In addition
it is increasingly being used as an effective method of non-destructive
testing (NDT) for the integrity of composite materials and structure.
Matrix cracking, delamination and fibre breakage are all mechanisms that
can produce AE signals when stress is applied.
applications include the detection and monitoring of insect infestations
including woodworm and termites in buildings and vine weevils in plant
