NDT Ultrasonic TestingUltrasonic thickness testing has been used widely to determine rate of corrosion and erosion, or detecting discontinuities below the surface of a variety of materials. Based on the same principal as sonar, a sound beam is transmitted into a material to determine thickness or soundness, and reflects back to the unit. This provides a thickness measurement with the accuracy of +/– .004" that can be trended for corrosion/erosion rate analysis.

The system uses a beam of pulsed ultrasonic energy between 20 kHz to 50MHz in range. The transducer is made of a piezoelectric material which is able to convert mechanical energy into sound waves and then reverse that process, sending the pulse to the ultrasonic equipment. Whatever testing is to be done requires the use of reference standards for calibration and flaw characterization.

Nova Data Testing Services utilizes equipment able to "auto calibrate" to the material being inspected and can inspect high temperature equipment. This allows us to inspect a wide variety of materials, while in process, in various environments. Our equipment also allows for thickness measurements through coatings. This means no more damage to the coating in order to acquire an accurate result.
