Air Gage | Air Gage Systems

In a case where you need to measure a much sensitive tolerance, in which is beyond a mechanical gage’s scope, Air Gages just might be the right tool to use.  An Air gage is an instrument used in a fast productive environment that needs an accurate and more sensitive case of measurements, and the key is the use of pneumatic pressure. Air Gages is often used to measure dimensions such as internal diameters, outer diameters, the depth, bore, taper roundness and thickness of an object, combined with either a dial display or an electronic digital display as its indicator.

A Dial display uses a needle or a pin pointer with a reference point of zero fixed in a graduated disc, that revolves around it indicating the accurate measurement of an object. While an Electronic Digital display is often used by air gages with data output capabilities, it displays either numerical or alphanumerical data’s, usually more accurate than a dial display.

Air plugs, Air rings, Air probes and Air gaging system are the several different types of Air Gages Some gages are portable handheld type, and there are also large, complex units in bench-top or floor-mounted configurations, which often comes with modified components such as a holder, in any case no special training or techniques are needed to use an air gage which makes this even better, it is as simple as 1 2 3, inserting an air plug in a hole, process then read the display, and that’s it.

An additional benefit of an air gage is the small gage head, that allows it to make measurements while it is still in the machine fixture with the air still running, it also cleans up the area from oil, dirt and chips.

Gage Calibration | Know Gage Calibration

As we have said before measuring equipments like gage block is vital to a quality controlled company, for it is the one we base for an accurate measurement of a certain product. Thus making sure that a measuring equipment is properly calibrated is important in quality control.

That is why a company must see the importance of gage calibration, they should see this as an investment, or as a discipline that is needed to be done for their quality assurances. If you think of it clearly, it's just like maintenance, everything needs to be maintained for a better performance just like a Gage Calibration, it's a process that must be done regularly.

A Gage calibration process is more than just a simple adjustment, as a matter of fact sets of test must be done in order to make sure the accuracy of the measurement is to the international standard, it is done by measuring a standard master artifact, in other words equally tracing an artifact in the National Institute of Standards and Technology. 

Gage users can do their own gage calibration process by setting up their own laboratory and perform the process, in which is what we call in-house, or they can send it to a professional company  which is trusted to do this calibrating service for them, or they could just return it back to the manufacturer for calibration services.

Gage owners or users usually use these three types of calibrating services, because calibrating process is not a quick one it takes time of at least three to six weeks before it is done. That is why It is wise to build your own In-house laboratory for your gage calibration, you would only need to invest on few facilities, equipments and trained personnel to do this, but in return you get a lower processing cost and faster turn around time.
