Transmitted or reflected light is often used to detect large gaps in webs or spacing between panels. However, that’s no reason not to use any aid or tool that has the potential to reduce risk and error alike. By using devices like this, you’re taking steps to ensure a project that’s free from errors or misaligned fittings while also increasing the safety levels of your tube fittings. Do All Manufacturers Require Fitting Installation Tools? Fixed—Fixed feeler gages, step gages, and gap gages use the fit of precision shims or spacers to measure gap. The gage is inserted into the gap or between the surfaces. The feel gage should just fit snug into the gap without forcing (overtightness) or looseness.Dial snap gauges – also called snap indicator gauges, add a display to the tool (either analog or digital) that provides an indication of the amount of deviation from the nominal value exhibited by the part being gaged. The deviation is a plus o

All feeler gauges are somewhat thin. This is because the point of them is to fit into and measure gaps that are far too narrow for most other common measuring tools, such as tape measures. A wire-type feeler gauge is a little different to the standard shim arrangement. Instead of featuring a series of graded metal leaves or blades, the wire feeler gauge instead has a series of rigid metal wires. For working with very delicate or easily scratched materials, you may be better off with a plastic feeler gauge than a metal one. The same is also true if you are working in environments where a metal version might corrode, conduct electricity, or cause sparking. It’s always a possibility that something will go wrong when you’re installing your fittings, just as it’s possible that anything could go wrong at any stage of any project. Gap sensor / gap switch—Gap sensors provide a dimensional measurement of gaps or clearances. Gap sensors do not typically have a visual display. Air, pneumatic, and electronic feeler gauges can be considered gap sensors or gap sensing instruments depending on their display capability. Gap switches, gap sensing switches, and gap sensor switches provide an output to trigger activate or deactivate factory machinery.Where gauges are showing wear on the front surface, the gauge can be reversed in the handle (applies to double ended reversible pin gauges). However, for many standard engineering and mechanical applications, tempered or stainless steel is often the preferred material. Brass can also be a good option if you need something durable, but somewhat softer and less likely to scratch than steel. Let’s say you’re working on repairs and trying to determine how much space you have between one tube fitting and the next, or between the tube joint and the wall. Whatever it is you’re trying to measure, this is where your gap gauge comes into play. A traceability statement in this section would be required for all items and their relevant certification utilised for the calibration of plain limit plug gauges. Gap sensors and feeler gages detect or measure the gap or clearance between two components or surfaces such as turbine blades tip clearance, nip or roller gap, lubricant gaps, weld seams, adhesive joints, extruder die gap, spark plug electrodes, generator or motor air gap, mold spacing, and workpiece-fixture gap. Gap sensing products use mechanical feel (feeler gages), air pressure, optical, capacitance, or other electronic technologies to sense gaps or clearance.

The plain plug gauges are the double-ended type for sizes up to 63 mm and of single-ended types of sizes above 63 mm. The plain plug gauges are designated by ‘GO’ and ‘NOGO’ as applicable. Types of Plain Plug Gauges in Normal Practice are It is necessary that any person carrying out such calibration work should have received appropriate training and have shown the ability to be confident via a suitable training authority. Training records should be held and maintained. Feeler Gauge: A feeler gauge, while it does mostly the same work as a more traditional gap gauge, looks slightly different in design. This tool consists of many folding leaves of metal, all connected at one central point. These leaves all then collapse together in a nesting format, similar to the ribs of a folding fan. This type of gauge is intended to measure the potential clearance between points, rather than tighten fittings. Fixed feeler gauges—Fixed feeler gauge and fixed step gages are mechanical gaging components used to measure gap, clearance, or spacing size. Angled feeler gauges are ones whose tips are bent over at a slight angle to the rest of the blade. This can be handy for accessing harder to reach gaps, where it may not be possible to slide a standard gap gauge in straight enough to get a good reading on the width of the opening. They are also known as offset feeler gauges. Feeler Gauge Sets

What Are the Benefits and Disadvantages of Using a Gap Gauge?

They will also likely be less safe. If the fittings and tubes aren’t as tight as they should be, it’s possible that gases and liquid will be able to leak out. This type of compression fitting failure could potentially cause safety hazards to those nearby.The issues present due to incorrect fitting installations might not be immediately apparent. It could be that initially, everything seems fine.

Capacitance—Capacitance gap gages measure by utilizing the change in capacitance that occurs when the spacing between two conductors changes. Measurement range – represents the mix/max values of the dimensions that the snap gauge can be used, As a rule, the smaller the measuring range, the higher the performance. Measuring force – usually in Newtons (N), represents the amount of force exerted by the gauge on the part surface when the anvils are closed

Care should be taken while using plain limit gauges. Should you drop a plain limit gauge, it should be re-calibrated/repaired before reusing it. A GO gauge represents the maximum material condition of the product and conversely, a “NOT GO” gauge represents the minimum material condition. 5. Pin Gauges This article presented a summaryof snap gauges, including what they are, the types, sizes & specifications, and uses. For information on other topics, consult our additional guides or visit the Thomas Supplier Discovery Platform where you can locate potential sources of supply for over 70,000 different product and service categories, including over 40 suppliers of snap gauges as well as suppliers of thread plug & ring gauges. Sources: Wouldn’t it be fantastic if instead of having to worry about your designated gap gauge, your fittings tightened themselves? That way, you wouldn’t have to worry about buying multiple gap gauges to fit each brand, training workers to use gap gauges or forgetting to carry these tools around with you.This is exactly what you’ll get when you shop at Mako Products — your U.S. source of Superlok fittings and technology. The question is, how harmful will it be in this case? Is this a mistake you could easily brush off, or is it one that could have debilitating consequences down the road?
