Tubes & bars (phased array)
Application example

ERW tubes inspection

Probes

Sector circular array probes

Technique

Electronic sector scanning
Pulse echo technique
Typical use in immersion, possible use in contact with appropriate delay line

Benefits

Electroacoustic performances: very high sensitivity and short pulse
Homogeneity of the performances over the elements of a probe and over the probes
Reliability in industrial using conditions including long term immersion
