Technology & Mounting
   Gaging Technology       
   Your choices are...         
   Air / Pneumatic       Gages or gaging systems use the changes in flow or pressure in air nozzles or inlets internally located in air plugs, probes, rings or snaps or other pneumatic gages. Pneumatic comparators, digital readouts, analog amplifiers, columns or flowmeter / rotameter tubes are used to display air gaging dimensional data. 
   IR       Infrared (IR) 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 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.  
   Electronic       Electronic gages use LVDT, capacitance, inductive or other electronic probes to sense the distance or displacement of a contact or stylus. Mechanical gages such as micrometers, plug gages, and snap gages may employ an integral electronic probe in addition to the mechanical gaging elements. 
   Magnetic       Magnetic techniques used in non-destructive testing include Hall effect and induction. 
   Mechanical       Mechanical gages use comparison or the physical movement and displacement of a gaging element (e.g., spindle, slide, stem) to determine the dimensions of a part or feature. Micrometers, calipers, indicators, plug gages, ring gages or snap gages are examples of mechanical gages. 
   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. 
   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. 
   Optical       Gages use optical, laser, or video-based technology to measure dimensional features.  
   Optical - Laser       Laser micrometers and gages are instruments that measure extremely small distances using laser technology. 
   Optical - LED       Gages use light emitting diode (LED) based technology to measure dimensional features. 
   Optical - Video / Imaging       Gages use imaging or video-based technology to measure dimensional features. A video micrometer projects two lines onto an object and provides a measurement of the distance between the two lines after calibration. 
   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. 
   X-ray / Gamma       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. Penetrometers or other X-ray opaque gage references are located with the part during imaging for sizing of internal cracks, pores, defects or other features. 
   Other       Other unlisted, specialized, or proprietary technology types. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Mounting / Loading:       
   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. 
   Benchtop / Floor       Devices are benchtop, table-based or floor mounted gages or instrument where a part is both manually loaded and measured. 
   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. 
   Other       Other unlisted, specialized or proprietary mounting or loading types. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Form       
   Your choices are...         
   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. 
   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.
