   Condition Monitor / Fault Detector       Condition monitors and fault detectors are designed to measure and record critical parameters and find faults in electrical, mechanical, optical, or other systems. For example, in an electrical system, an arching circuit breaker is a type of fault. In a mechanical system, a failed roller bearing is a type of fault. Both mechanical and electrical faults produce characteristic sounds, which fault detectors discover by using air or structure-borne acoustic detection techniques. 
   Flaw Detectors       Flaw detectors are instrument or systems used to detect and measure flaws in materials.

   Acoustic Emission       Acoustic emission instruments are designed to monitor conditions and detect changes in mechanical, electrical and process systems. In electrical power distribution systems, they are used to detect shorting or arcing. In mechanical systems, flaws also provide specific acoustic or vibrational responses. For example, if a break, deformation or other failure occurs, acoustic emission (AE) sensors can detect the burst of high frequency caused by the event. Continuous acoustic emissions are associated with dislocation movement and the resulting strain or deformation. Bursts or short pulses of acoustic emissions signals are produced by micro-yielding, twinning, and crack formation. Melting, phase transformation, thermal stresses, fiber breakage and fiber-matrix debonding in composites also result in acoustic emissions.    Monitoring acoustic emissions can also access the location and severity. This NDT technique is particularly useful in determining the structural adequacy of tanks and pressure vessels.  AE is also used for the detection of faults or leakage in pressure vessels, tanks, and piping systems. Welds and stress corrosion cracking can be monitored on-line with AE techniques. 
   Air / Structure Borne       Air and structure-borne detection methods are used to detect faults in electrical and mechanical system based on the detection of acoustic signals. These signals can be airborne, travel through the air, or reside only within a solid structure or mechanical system.  There are many applications for air or structure-borne ultrasonic detection or inspection methods. Examples include: 
  • Access Door or Hatch Leaks
  • Bearings
  • Chillers, Air Conditioners and Cooling Systems
  • Circuit Breakers, Fuses and Switches
  • Compressed Air Leaks
  • Distillation Columns
  • Electrical Systems (Arcing, Corona or Tracking)
  • Gears and Gear Boxes
  • Heat Exchanger, Boiler, and Condenser Leaks
  • Mechanical Systems
  • Motors
  • Pump Cavitation
  • Specialty Gas Systems
  • Steam Traps
  • Switchgear, Busbar, Busways and Panel boards
  • Tanks, Tubing, Hose and Pipes Leaks
  • Under or Over Lubrication 
  • Vacuum System Leaks
  • Valve Leaks
  • Water Leaks
  • Wind Noise
 
   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. 
   Magnetic Particle System       Magnetic particle systems use current flow or an external magnet to magnetize the part. Magnetic poles that are created at flaws, cracks, and other discontinuities attract magnetic particles made of fine iron oxide (0.125 to 60 microns). These particles have a high permeability (easily magnetized) and low retentivity (ability to stay magnetized). Three methods are typically applied: dry nonfluorescent, wet nonfluorescent, and wet fluorescent. 
   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. 
   Penetrant Testing System       Penetrant testing systems apply a penetrant to the part via spray or immersion. The penetrant is pulled into surface flaws by capillary action. Next, a cleaner is used to remove residual penetrant from the surface of the part so that only the liquid penetrant remains in the surface flaws or cracks that are present. Penetrant systems are available with varying sensitivity levels, depending on the material and flaw type being inspected. For example, red dye penetrants are visible under normal light. Fluorescent penetrants or penetrant systems may require ultraviolet (UV) or backlight illumination. Developers or fluorescent powders may be required to enhance visibility of the residual or crack-entrapped penetrant. 
   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.

   Your choices are...         
   Aircraft / Military Inspection       Aircraft or military-quality inspection instruments are suitable for inspecting aircraft, rocket motor casings, torpedo housings, weapons, military vehicles, and other components for critical military, aerospace, or naval applications. 
   Coating Flaw / Holiday       Coating flaw or holiday detectors designed to find coating flaws such as pin-point discontinuities, openings (holidays), thin spots, bubbles, blisters, inclusions, streaks, waviness, and chicken tracks. 
   Debonding / Bond Integrity       Debonding and bond integrity instruments are designed to detect delamination, bond failures, incomplete bonding, bond porosity or gaps, and inclusions/contamination in the bond interface. 
   General Corrosion Detection       General corrosion detection instruments are designed to detect internal or external corrosion caused by chemical attack or oxidation due to high-temperature gases. 
   Inclusions       Inclusion detection instruments are designed to find inclusions, undesirable secondary phases or contaminant particles (such as oxides) in metal alloys. 
   Machining / Grinding Damage       Instruments are designed to detect damage from machining or grinding. Machining damage can occur in metallurgical or mechanical forms. Grinding burn, decarburization, surface softening, and the formation of surface martensite are other metallurgical or material condition changes that can occur. Seams, laps, or pits may be caused by either mechanical or chemical machining damage. 
   Metal Detection / Rebar Absence       Metal detection or rebar absence instruments can detect metal chips in pharmaceutical powders, or metal rebar in concrete bridges or buildings. 
   Manufacturing - Metals / Web       NDT instruments for metals and webs are used in industrial environments to monitor thickness, defects, or material properties during the continuous processing of primary metals or webs. Webs include plastic films, paper or paperboard, woven fabrics, metal foil or strip, nonwovens, and other continuous sheet products. 
   Packaging Defects / Leaks       Packaging defect and leak detection instruments are suitable for detecting holes, leaks, cracks, defective seals, channel leaks, contaminated materials, missing product, or closures. 
   Pore / Void       Pore or void detection instruments can detect empty pockets or cavities within a material. 
   Pressure Vessel Flaws / Cracks       Instruments are designed to detect surface or sub-surface cracks, inclusions, or pores in boilers, digesters, reactors, and other pressure vessels. Because most pressure vessels are made of steel, NDT techniques for ferrous alloys are typically used. In large-scale industrial units, the NDT instruments or probes are often used in combination with a scanner.  Pressure vessel failure can result in loss of life, operating losses due to downtime, and a considerable capital expense to replace the unit. Therefore, pressure vessel flaws and cracks are monitored as part of a predictive maintenance (PM) program. 
   Rail Inspection       Rail inspection instruments are used to inspect railroad tracks or railroad car components 
   Subsurface Crack Detection       Subsurface crack detection instruments are designed to detect cracks below a materials surface. Ultrasonic, eddy current / electromagnetic, radiographic, acoustic emission, and magnetic technologies are often used in subsurface crack detection. 
   Surface Cracks / Abrasion       Surface cracks, flaws, and abrasions are detected with magnetic particle inspection, penetrant testing, and visual inspection techniques. 
   Tube / Pipeline Defects       NDT instruments for tubes and pipelines are designed to detect surface or sub-surface cracks, inclusions, or pores in tubing, piping, or pipelines. Because pipelines are usually made of steel, NDT techniques suitable for ferrous alloys are typically used. Since a conduit's length and internal diameter (ID) can cause difficulties in terms of operator access, these instruments or probes are often used with a scanner that can travel internally or externally down the pipeline.  Pipeline cracks or flaws can result in loss in life, operating losses due to downtime, and a considerable capital expense to replace the damaged section. Therefore, pipeline cracks and other flaws are regularly monitored as part of a predictive maintenance (PM) program. When a detected flaw or an imminent flaw exceeds safety limits, the pipe or tube can be repaired or replaced for continued safe operation. Special automatic, in-line inspection systems are also used to examine pipes or tubes during production. 
   Weld / Joint Inspection       Weld and joint inspection instruments are used to detect incomplete fusion, cracking, inclusions, or porosity. 
   Wire Rope / Cable Tester       Wire rope or cable testing instruments are designed to detect surface and subsurface cracks, construction defects, flaws, internal warping, internal corrosion, or inclusions in cable or wire rope. Because wire rope and cables are usually made of steel, NDT techniques suitable for ferrous alloys are typically used.  Cable and wire ropes are used in aircraft and bridges, for seismic building support, and as tower guy wiring where failure can result in loss of life, operating loss due to downtime, and considerable capital expense to replace a damaged structure. Therefore, cracks or other flaws are regularly monitored as part of a predictive maintenance (PM) program. When a detected flaw or an imminent flaw exceeds safety limits, repairs or replacements are made so that the structure can continue to operate safely. Special automatic, in-line inspection systems are also used for inspecting wire rope and cable during their production. 
   Other       Other unlisted or unspecified methods of flaw detection.
