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. 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. Mechanical—Large gaps can be measured with an internal or ID mechanical gage. Mechanical gap gages are usually called internal gages or inner diameter gages. Roller gap gages and gap micrometers are examples of mechanical gap gages. Fixed gap or feeler gauge could be considered mechanical gage without moving parts. It is highly recommended that an appropriate authority such as a UKAS approved laboratory carries out a full calibration on plain limit gauges at least once a year. In between UKAS calibrations at a frequency based on usage, plain limit gauges should be calibrated in-house. A typical in-house calibration would include a written procedure and an associated calibration record sheet, which would contain as a minimum, the following listed information: Plain limit gap gauges

A gap gauge is an excellent tool to keep with you as you work on installations, fittings and repairs. It helps give you an extra level of peace of mind when it comes to installing your fittings, as you can more confident that the work you’re doing is secure, stable and completely tightened.The question of whether or not they’re necessary is a difficult question to answer. 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.

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

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. The result will be an installation that is connected much more tightly and securely than it would have been otherwise. This, in turn, leads to greater safety and stability. Fixed feeler gauges—Fixed feeler gauge and fixed step gages are mechanical gaging components used to measure gap, clearance, or spacing size. 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

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?It depends on the exact nature of the error in the fitting installation. It’s possible that the problem is so small it will never be noticed. It’s also possible that the mistake was so large it can destabilize the entire network of fittings and cause severe damage.The most likely outcome is that your fittings will be less stable than they should be. 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.

Double-ended snap gauges – these types of snap gauges have a double C frame with the go gauge on one end or side and the no-go gauge on the other side rather than nested within a single set of jaws as with the combined limit gauge.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: A blade feeler gauge is probably the most common type of gap gauge you will encounter when shopping for these tools online. They usually feature a range of graded flattened metal shims or leaves which are designed to fold in or out of a central case or sheath. 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. 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. There are several methods available to determine the dimensions of components in a system of limits and fits. The method of measurement adopted for mass production of parts is called the system of limit gauging. It has an advantage that it can be operated by unskilled persons.
