Welcome to the AVT Acoustic Emission Sensor web site
AVT have been producing high quality Acoustic Emission Sensors (AE Sensors) and Instrumentation for over 25 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 is mandatory. AE sensors are highly sensitive listening devices that form the vital link between the structure or material under test and the analysis instrumentation. Acoustic 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. AE 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. More bizarre applications include the detection and monitoring of insect infestations including woodworm and termites in buildings and vine weevils in plant nurseries.
