Dual Element TransducersTwo angled elements create a V-shaped sound path in the test material. This "Pseudo-Focus" enhances resolution in the focal zone. A dual element transducer consists of two crystal elements housed in the same case, separated by an acoustic barrier. One element transmits lon gitudinal waves, and the other element acts as a receiver. Advantages:
