ポータブル超音波／渦流探傷器
TOFD探触子
TOFD探触子&ウェッジ
TOFD探触子とウェッジは、屈折した縦波を鋼材中に生成させ、TOFD(Time of Flight Diffraction)法によって割れの大きさをサイジングするために使用します。
Advantages
Our time-of-flight diffraction transducers are highly damped longitudinal wave probes that offer excellent resolution in challenging TOFD applications. These highly sensitive composite element broadband transducers are available in frequencies from 2.25 MHz to 15 MHz and in sizes from 3 mm (0.25") to 12 mm (0.50"). They are for use with specialized TOFD wedges designed to produce refracted longitudinal waves in steel.
