Instrument Type / Technology
           
   Your choices are...         
   Acoustic Emission       Specific flaws or features within a mechanical system provide specific acoustic or vibrational responses.  If a break, deformation or other failure occurs in a piece of equipment, the high frequency burst given off during the event can be detected by sensitive acoustic emission sensors.   The location and severity can also be accessed by monitoring the acoustic emissions.  The NDT technique is particularly useful in determining the structural adequacy of tanks and pressure vessels. 
   Air Gage       Gages or instruments used to measure the thickness of metal sheet or strip, plastic webs or films, and other thin materials or sections of components.  Micrometers, calipers, laser micrometers, and indicating thickness gages are commonly applied in gaging thickness. 
   IR / Nuclear       IR, nuclear and beta gauge instruments use the absorption of radiation to measure the thickness or basis weight of webs, sheet materials or coatings.  On nonmetallic materials such as paper or plastic films or webs, the amount of radiation 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. The gauge is often calibrated with sample of known thickness, density or mass.  The radiation source used can be IR (infrared electromagnetic), nuclear (beta particles) or other radiation sources (x-ray, gamma rays) and will depend on the material and inspection conditions. 
   Eddy Current / Electromagnetic       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 current 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. 
   Electronic Gage       Gages or instruments used to measure the thickness of metal sheet or strip, plastic webs or films, and other thin materials or sections of components.  Micrometers, calipers, laser micrometers, and indicating thickness gages are commonly applied in gaging thickness. 
   Optical - Laser       Laser micrometers and gages are instruments that measure extremely small distances using laser technology. 
   Magnetic (Hall Effect, Induction)       Any one of several different magnetic techniques is used in non-destructive testing. 
   Mechanical Gage       Gages or instruments used to measure the thickness of metal sheet or strip, plastic webs or films, and other thin materials or sections of components.  Micrometers, calipers, laser micrometers, and indicating thickness gages are commonly applied in gaging thickness. 
   Micrometer       Micrometers are instruments for precision dimensional gaging.  They consist of a ground spindle and anvil mounted in a C-shaped steel frame. Micrometers are available in scale, digital, and dial variations. 
   Optical / Laser       Optical based instruments using methods such as laser shearography, magneto-optical, holographic interferometry or other optical techniques to detect flaws, residual stress or measure thickness. 
   Radiographic / X-ray       Equipment using penetrating x-ray or gamma radiation to capture images of the internal structure or a part or finished product.  The density and composition of the internal features will alter the intensity or density of these features 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. 
   Snap Gage       Snap gages are functional or attribute gages used in production settings where specific diametrical or thickness measurements or go / no-go assessment are repeated frequently.  They provide a fairly high degree of precision compared to other gages. 
   Ultrasonic       UT inspection techniques are used to detect surface and sub-surface 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 being evaluated.  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. 
   Other       Other non-destructive techniques or technologies not listed.

Form / Mounting
           
   Your choices are...         
   Automatic / Inline       The part is automatically presented to the gage and measured without operator intervention. Inline devices are automatic gages used in a production line. In semi-automatic systems, a part is presented manually to the gage or gaging system and then measured automatically. 
   Bench / Rack / Floor       The device is a stand alone unit that can be placed on a bench, desktop, or it can be rack mounted. Benchtop, table-based or floor mounted gage or instrument where a part is both manually loaded and measured. 
   Gage Head / Probe       Gage heads or probes are electronic, pneumatic, optical, or mechanical gaging units that connect to a remote display, readout, or analog amplifier.  In some applications, probes are used in conjunction with other gages, such as a plug gage with an integral electronic probe. 
   Gage Set / Tool Kit       Gage sets include several gages and accessories packaged into a kit, usually in a case with adjusting tools. Tool kits sometimes contain alternate extensions and contact tips, holders, bases, or standards. 
   Gaging System / Station       Gaging systems or stations are larger, more complex units for large-scale gaging. They are usually available in bench top or floor mounted configurations. These devices may consist of several gages, fixtures, or other components for holding or manipulating parts during inspection.  Typically, systems or stations have specialized gaging or inspection systems customized for particular OEM application.  Air gaging stations, gear testing systems, form gaging systems, tire profiling systems, and universal gaging systems are example of these types of products. 
   Handheld / Portable       Devices can be operated while being held in the hand and/or are portable. 
   Machine Mounted       Gages are mounted on or within a machine tool or equipment for tool setup or travel measurement. Test indicators, dial indicators and micrometer heads are examples of gages that are often machine mounted. 
   Monitoring System       Monitor or monitoring system to continuously detect or measure flaws, thickness or corrosion in production line, plant or field applications. 
   Other       Other unlisted or proprietary form factor.
