Thickness Gages Information Thickness gages are used to make precise dimensional measurements on coatings and materials such as steel, plastic, glass, rubber, ceramics, paint, electroplated layers, and enamels. They differ in terms of performance specifications, applications, and features. There are three main performance specifications to consider when selecting thickness gages: thickness range, thickness resolution, and number of channels or probes. In terms of applications, these instruments...

Q:
What new technologies are influencing thickness gage design?
14 answers
Answers:
If the gage is Ultrasonics, then the one that can penetrate the coating and is the size of a play station and is computerized. If the gage is for physical measurements the swiss army knife type which is adaptable to all required jobs. The main area is pitting, a good gauge including corrosion pitting is hard to find and is the most important in the petrochemical industry.
~Thomas C, Quality Control, Doha, Qatar
Very thin layers, nonuniform thickness platings, gage' s measuring tip, round surfaces; concave and convex, deep grooves and holes, out-of-reach workpieces.
~Abdel- Aziz K, General Management, Cairo, Egypt
First of all people see whether the equipment is rugged and environmentally sealed to most harsh environments. Next comes the consistent readings and resolution.

Q:
From your perspective, which companies are creating the most innovative thickness gages?
15 answers
Answers:
For me it started with the welding institute but seen that it was too expensive and was not designed for accurate pit gaging. Now made in China is the best, they have the price, quality and technology.
~Thomas C, Quality Control, Doha, Qatar
Most of them follow same technology but some are very efficient.

Applications and UseTop

Q:
What are some of the applications you have used thickness gages for?
39 answers
Answers:
Applications: Have been using thickness gauges for over 3-decades, mainly for thickness gauging of tanks, plates, oil and gas pipelines for corrosion measurements and other metallic objects etc. I have found them to be mandatory for chemical and petrochemical industries and also for marine structures. The thickness gauges are an integral part of quality control procedures.
~Engineering, Other, Karachi, Pakistan
Ultrasonics for metals used in Petro-chemical industry. Gages as above and including weld preparation, plates, ships hulls, pipes, vessels, tanks, offshore and offshore. Odd shapes that require thickness either approximate or accurate.
~Thomas C, Quality Control, Doha, Qatar
In the repair and machining of different type of bearings for the different sizes and also in the alignment of the different rotary parts ( turbines, fans, pumps , etc.).

Q:
Please share with us any “non-standard” applications that thickness gages have been used for.
8 answers
Answers:
As above I use a paper clip in small holes and use my thumb to measure the depth from the end of the pin. No gage includes calipers for actual wall thickness or knife that is used for preparing the dirty area.
~Thomas C, Quality Control, Doha, Qatar
Like bottom of oil tanks, bones inside life human body, shafts inside m/cs without need to get a certain suspected shaft out.
~Abdel- Aziz K, General Management, Cairo, Egypt
The thickness gauges can also be used not only on metals but non-metals too.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of thickness gages?
7 answers
Answers:
Without using gages in the proper time, fracture of petrol engines when wear of crank shaft causes connecting rods to escape untightening bolts and attack the engine walls. The same can occur if we used the gage not normally or in the wrong area or moved carelessly from the measuring position.
~Abdel- Aziz K, General Management, Cairo, Egypt
No. We all show different thickness and pitting depth. Not every inspector has a gage, having any gage increases the chance of accurate reporting. At the end of the day we all want accurate reports, not assumptions.
~Thomas C, Quality Control, Doha, Qatar
Incorrect measurements in food packaging films are very crucial to film manufacturer (lost packaged goods and bigger loss in reputation).

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
14 answers
Answers:
Angle for weld. Depth of misalignment from outside. Accurate pit gauge. Ruler. Usable on fillet welds for leg length and throat thickness. Dimensions in mm. Durable. Under 50$ A very thin attachment that would penetrate a hole to measure depth, similar to a needle but no point. Have a built in knife. Measure plate thickness using calipers.
~Thomas C, Quality Control, Doha, Qatar
Obtaining the thickness' measurement at chosen specified accuracy at a point, multi points, getting the result mean value, able to locate the most different areas on the work piece surface, remote measuring for out-of reach areas.
~Abdel- Aziz K, General Management, Cairo, Egypt
Easy handling, reliable, good R&R value, resolution down to 1 micrometer, image/data capture

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using thickness gages?
9 answers
Answers:
Thickness measuring for used parts is like life time prediction, very useful, very dangerous, maybe fatal in some cases. In the meantime, it's time and money saving if you know when, where, how and how practically to use data obtained afterwards.
~Abdel- Aziz K, General Management, Cairo, Egypt
Use only gages which can measure the structure of film completely. For instance you can have all individual thicknesses in structure A-B-C-B-A, not only added thicknesses of two A layers or two B layers.
~Vesa, Builder/Contractor, Helsinki, Finland
Yes as the fellow coaters should also use very accurate gauges and it should be calibrated at least once in a year.
~Hiren Parikh, Managing Partner, Ahmedabad, India
First of all you should see the online demo and should qualify whether it is really worth buying that model.
~Sudheer Krishnan, Inspection engineer, Chennai, India
Check out Chinese gauges, they are good and well priced.
~Thomas C, Quality Control, Doha, Qatar
Do NOT buy a toy. Good tools give reliable results.
~Wm M, Technical Consultant, Ooltewah, TN
Question others in the industry that you use.
~Thomas Buelter B, Process Engineer, Saint Louis, MO
Not knowledgeable enough to say.
~Customer liason, Milford, CT
Choose the best quality.
~Reuven Porat, Technical Support, Nahariya, Israel

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of thickness gages?
8 answers
Answers:
Keep the gage at right angle to the work piece, avoid longer time for measuring, keep your breath off till finish, repeat measuring for the same spot and compare the results, get the identical values to consider. for big areas, choose the most mating surface areas to measure and compare by plain, out of mating areas. Avoid using aided parts like fragiles for round surfaces to transfer the dimension as far as possible.
~Abdel- Aziz K, General Management, Cairo, Egypt
Use gages which have no errors depending on temperature of film and which have no need for recalibrations after every change in produced films.
~Vesa, Builder/Contractor, Helsinki, Finland
Never choose a gauge for one job. Choose gages that save money, time and effort. Choose quality and price.
~Thomas C, Quality Control, Doha, Qatar
We should have at least two standard refrance strips as one gent worn out very fast.
~Hiren Parikh, Managing Partner, Ahmedabad, India
Check several parts of what you are testing to come up with the best average.
~Customer liason, Milford, CT
Protect your self from X ray radiation
~Reuven Porat, Technical Support, Nahariya, Israel
Don't buy the cheapest on the market
~Thomas Buelter B, Process Engineer, Saint Louis, MO
Don't try to save $$$.
