  • SmartMoves TM Spotlights: Andrew NDT Engineering (.pdf)
    . these critical depositions cost more than a million dollars. Andrew NDT’s metrology. Other methods use thermal waves that are often unstable. machines tested with. Andrew NDT’s patented new approach solves both. Galil controllers have. problems with a special capacitance probe that measures. the thin
  • Electromagnetic NDT Testing
    Eddy current, ground penetrating radar (GPR), and other electromagnetic NDT testing techniques used to detect or measure flaws, bond or weld integrity, thickness, electrical conductivity, detect the presence of rebar or metals. The eddy current method is the most widely applied electromagnetic NDT
  • Using Eddy Current Test Techniques to Verify the Number of Bearings in a Bearing Assembly
    Ultem 1000. This. is a plastic material with excellent wear characteristics that is often used by NDT. Technologies for probes where little or no shielding is necessary to isolate the eddy current. signatures of the bearings themselves. In this case also, the probe was designed so that an. upper
  • Q & A Related to Eddy Current Test Systems
    . The principal means of evaluating samples in the NDT Technologies systems is based on statistics. Since the eddy current probe simultaneously extracts four materials characteristics (chemistry, geometry, hardness and temperature) from every sample, the review of any sample population with respect
  • Microwave Nondestructive Testing of Composite Materials using Free-Space Microwave Measurement Techniques
    Microwave Nondestructive Testing (MNDT) techniques have advantages over other NDT methods (such as radiography, ultrasonics, and eddy current) regarding low cost, good penetration in nonmetallic materials, good resolution and contactless feature of the microwave sensor (antenna). For MNDT
  • Pipeline Defect Flaw Detectors
    often create difficulties in operator access, so the NDT instruments or probes are often used in combination with a scanner that can travel internally or externally down the pipeline. Pipeline cracks or flaws can result in a loss in life, operating loss due to down time and a considerable capital
  • Eddy Current Testing
    Eddy current, penetrating radar and other electromagnetic techniques used to detect or measure flaws, bond or weld integrity, thickness, electrical conductivity, detect the presence of rebar or metals. The eddy current method is the most widely applied electromagnetic NDT technique. The eddy
  • Lead Metaniobate (PN)
    (NDT) transducers where low QM and clean impulse response are required. Underwater sonar equipment utilizes lead niobate because the material has a high longitudinal coupling compared to its lateral and planar coupling allowing it to generate a better response under hydrostatic pressures.
