Waygate Technologies Angle Beam Transducers

Waygate Technologies angle beam transducers are single beam units that are designed for use with the Waygate Technologies USM Go flaw detector. These transducers use refraction to transmit shear or longitudinal wave at a predetermined angle and are preferred for parts with inclined flaws, such as welds. Wedges (sold separately) are used to hold the unit at the desired angle. A layer of couplant is required between the transducer and the material being tested.

Waygate Technologies angle beam transducers are ideal for general weld inspection as well as identifying flaws on pipes, tanks, pressure vessels, containers, axles, forgings, castings, pumps, valve housings, bridges and other structures, railroad wheels and rail, turbine blades, shafts, wheel rims, and others.

Waygate Technologies offers three performance ranges for angle beam transducers:

Gamma Series Features

• General purpose transducers, recommended for the majority of applications
• Medium pulse, medium damping—best combination of gain and resolution
• Matching electrical network ensures maximum gain and optimum waveform for general use
• Medium bandwidth—typical 6 dB bandwidths range from 30% to 50%
• Typical Gamma waveform exhibits three to four full ring cycles, depending on frequency, size and other parameters

Benchmark Series Features

• Proprietary BENCHMARK COMPOSITE® (piezocomposite) active elements
• Penetration in attenuative materials is far superior to conventional transducers
• High signal to noise on coarse grain metals, fiber reinforced composites, et al.
• Short pulse—resolution usually superior to Gamma Series
• Gain is usually higher than that of the Gamma and Alpha Series
• Very broadband—typical 6 dB bandwidths range from 60% to 120%
• Low acoustic impedance element improves performance of angle beam, delay line, and immersion probes—excellent match to plastic and water

Alpha Series Features

• Recommended for applications where resolution is the primary consideration
• Suitable for applications such as thickness measurement and near-surface flaw detection
• Very short pulse—mechanically damped to the limit of current technology
• Gain is usually lower than that of the Gamma and Benchmark Series
• Broadband—typical 6 dB bandwidths range from 50% to 100%
• Typical Alpha waveforms exhibit one to two full ring cycles, depending on frequency, size and other parameters
