Los sensores de Physical Acoustics están diseñados para «escuchar» señales de alta frecuencia. Al igual que un «oído» de alta sensibilidad, los sensores de emisión acústica interpretan la «voz» del material en formas de onda AE utilizables. Además, los sensores AE ayudan a entender cómo se comportan los materiales en su entorno natural.
Los sensores AE son un eslabón vital para determinar cómo aplicar soluciones correctivas y reparaciones para resolver problemas estructurales. Los sensores AE se utilizan para probar tanques de almacenamiento, intercambiadores de calor, tuberías, reactores y dispositivos de elevación aérea, así como en centrales eléctricas de gas, petroquímicas y nucleares. Los sensores de Physical Acoustics se pueden construir con características específicas para satisfacer las necesidades específicas de un proyecto o aplicación.

| Miniature PICO |
200 – 750 kHz |
Any application with a noisy
environment and requiring
a small size, midband frequency
response.
Their high sensitivity and bandwidth
makes them ideal for structural health
monitoring of critical structures
like aircrafts, storage tanks etc.
Typical applications include monitoring
for fatigue and corrosion cracking
in metals, delaminations and fiber
breakage in composites.
It can easily be mounted using epoxy
and can be mounted in small and
tight spaces. |
Model PICO |
Underground
R15-UG |
50-200 kHz |
Structural health monitoring of
underground structures like
pipelines, oil tanks, tunnels etc.
They can also be used for monitoring
geological structures
and seismic activity. |
Model R15-UG |
Underwater
R15I |
50-400 kHz |
Structural health monitoring of
submerged structures like offshore
oil and gas platforms, ships etc.
They can be used inside any liquid filled
platforms like pipelines, chemical tanks
or any other submerged structures. |
Model R15I-UC |
Wideband
F301-AST-150-750 kHz |
150-700 kHz |
Flat response of these sensors help
eliminate the sharp rise and fall
in the sensitivity with frequency
commonly seen in resonant sensors,
providing additional information for
engineers to analyze.
Are well suited for research
applications where a high fidelity
AE response is required. |
