Technology
   Technology:       
   Your choices are...         
   IR / Nuclear       Infrared (IR), nuclear, and beta gauge instruments use the absorption of radiation to measure the thickness or basis weight of webs, sheet materials, or coatings. With nonmetallic materials such as paper or plastic films or webs, the amount of radiation that is reflected back or transmitted through the material is measured to determine absorption levels. An increase in mass, density or thickness will result in increased absorption. Often, the gauge is calibrated with a sample of known thickness, density or mass. The radiation source used can be IR (i.e., infrared electromagnetic), nuclear (i.e., beta particles) or other (e.g., x-ray, gamma rays) and depends upon the material and inspection conditions.  
   Eddy Current / Electromagnetic       Eddy current, penetrating radar, and other electromagnetic techniques are used to detect or measure flaws, bond or weld integrity, thickness, and electrical conductivity, and to detect the presence of rebar or metals. Eddy current is the most widely applied electromagnetic NDT technique. This method is also useful in sorting alloys and verifying heat treatment.  Eddy current testing uses an electromagnet to induce an eddy current in a conductive sample. The response of the material to the induced current is sensed. Since the probe does not have to contact the work surface, eddy current testing is useful on rough surfaces or surfaces with wet films or coatings. 
   Electromagnetic Acoustic Resonance       Electromagnetic acoustic resonance (EMAR) uses a non-contact electromagnetic transducer to impart a signal for resonant acoustic analysis. The non-contact EM-induced signal produces a pure resonant response. Mechanical vibration from surrounding machinery does not influence the ultrasonic signals in the materials or parts being inspected. Localized or wide acoustic fields can be generated, depending what features need to be isolated and measured. Small surface or subsurface flaws or anomalies can also be isolated. Specifically, the entire part can be resonated for elastic stiffness and structural integrity assessments. 
   Magnetic       Magnetic techniques used in non-destructive testing include Hall effect and induction. 
   Optical / Laser       Optical-based NDT instruments use techniques such as laser shearography, magneto-optical methods, and holographic interferometry to detect flaws and residual stress, or to measure thickness. 
   Radiographic / X-ray       Radiographic or X-ray equipment uses penetrating X-rays or gamma rays to capture images of the internal structure of a part or finished product. The density and composition of the internal features will alter their intensity or density in the X-ray image.  Densitometers are used to quantify the density variations in the X-ray image. Penetrameters or other X-ray opaque gage references are located with the part during imaging for sizing of internal cracks, pores, defects or other features. 
   Ultrasonic       Ultrasonic (UT) inspection techniques are used to detect surface and subsurface flaws, or to measure thickness. Beams of high frequency acoustic energy are introduced into the material and subsequently retrieved. Distance calculations are based on the speed of sound through the material under evaluation. The most widely used of all UT techniques is the pulse-echo technique. Flaws are detected and sizes estimated by comparing the amplitude of a reflected echo from an interface (flaw or back surface) with that of a reference interface of known size.
