Dakota Ultrasonics flaw detectors use ultrasonic technology to pass sound waves through metals, composites, plastics, and ceramics to identify anomalies such as cracks, voids, and softness. In ultrasonic testing, a transducer is used to both create vibrations and receive the echo that returns, and the returning signal can be converted into a waveform pattern to be analyzed. Common applications include aerospace, oil and gas and power generation. Dakota Ultrasonics offers the DFX series which is an ultrasonic thickness gauge and flaw detector in one compact unit. Configuration options are available.
