Measuring and control instruments are very important resources in any production process.  During any process, there are many parameters and properties that need to be carried out with precision to guarantee that high quality standards are met.

So, how to choose the best supplier for measuring and control instruments?

5 aspects to consider when choosing your measuring and control instruments supplier

There are different aspects you should consider when selecting your measuring and control instruments provider. The most important ones are the following:

1. Quality of the instruments

This may sound obvious, but the quality of the measuring and control instruments is of uttermost importance, since this will have a great impact on the results of  all your Quality Control (QC) and Quality Assurance (QA) activities.

For example, S.A.M.A. Italia is a UNI EN ISO 9001 certified company.  A certified supplier confirms that you are choosing a company with clear procedures, aimed at providing accurate services.

S.A.M.A. Italia is a supplier that operates worldwide and supplies companies with its own name-brand SAMA Tools instruments.  Therefore, a reliable and experienced supplier from whom you can receive high quality tools.

Moreover, all SAMA Tools instruments are manufactured to comply with the reference standards.

2. Calibration

As defined by the experts at S.A.M.A. Italia, “calibration means to identify metrological characteristics of a measuring instrument.  It can be defined as a “photograph” of the instrument in its current state. This is the result of a comparison with a reference sample and does not contemplate the adjustment of the instrument.”

This is an important aspect because one can purchase a “quality” instrument which is not calibrated, and therefore, may need adjusting. As a result, the instrument won’t work properly and it will most likely cause problems.

To prevent this from happening, S.A.M.A. Italia offers calibration services and supplies Laboratory Test Reports in compliance with UNI CEI EN ISO/IEC 17025 and ACCREDIA certificates on all their instruments, but also on equipment you may already own and of other brands.

How often should the measuring instruments be calibrated? We talked about it here.

3. Destructive or non-destructive testing instruments?

When we talk about measuring and control instruments, we generally mention two categories: destructive and non-destructive testing instruments.

As the name implies, destructive testing requires altering or destroying the sample in order to identify its mechanical characteristics.

If you want to carry out measurements and tests in your production process without damaging your sample, the best alternative is non-destructive testing, such as:

  • Visual tests
  • Flaw inspection
  • Roughness measurement and control
  • Ultrasonic thickness control
  • Coating thickness control
  • Hardness testing
  • Environmental control

This will allow you to directly identify properties and mechanical features on the final product without damaging it. And SAMA Tools offers you the best instruments for each of these tests.

4. Technical support

When we see the words “technical support”, most of us immediately think  about fixing or repairing something. However, the technical support you should look for when selecting your measuring and control instruments provider must be a more complete kind of service.

As the S.A.M.A. Italia Export Manager Martina Guatteri says,: “It is well known that every successful company has excellent after-sales assistance.” This should be part of what you should look for”, but as she also says, “pre-sales assistance is also very important.”  Yes, S.A.M.A. Italia ships its tools worldwide!

It’s important to find a supplier that can really understand your needs and provide you with the best solutions for you,  keeping your best interests at heart.

Moreover, having solid technical support means making sure you won’t have any problems while using the instruments, and assistance on how to use them properly.

S.A.M.A. Italia offers all their customers a complete metrological consultancy service and care for every need from the very beginning. They help you become an independent user of their instruments, with specialized technicians that will assist you during installation, if required, and during the first stages of testing and measuring. And you will gain an understanding that goes far beyond simply reading a manual.

5. Do you need portable instruments?

It is not always possible to install a device in a laboratory or withing processes to test and measure important parameters. Most of the time, when dealing with QC and QA, you need to measure “on the fly” and this means having a light and portable tool, suitable for measuring in the field.

S.A.M.A. Italia can provide you with a wide range of portable instruments while maintaining the highest quality on the market.

Some examples of portable tools are:

  • Portable surface roughness testers

Are you looking for information on how to use an ultrasonic thickness gauge to measure the thickness of any given material reliably?
Read on to understand how you can accurately use the gauge, just like our client, Project PSC does.

What is an ultrasonic thickness gauge?

An ultrasonic thickness gauge is an electronic device that uses the emission and reception of sound waves to measure the thickness of a given material.
It comes in different sizes and has various functions.
Each sector requires one type rather than another, therefore it is important to choose the most suitable model for each need.

probe thickness gauge

How does the ultrasonic thickness gauge work?

First,  you need to know what you have to measure. Each material has a different internal sound speed, which means that sound travels through different materials at different speeds.
This is an essential part of calculating the thickness of a material, because the thickness is equal to the echo cycle time divided by the sound speed.

To accurately calculate the thickness, the device must know the speed of the sound within the material it is measuring.

Since this is specific to the material itself, it is important to set the device for the material you want to measure.
Let’s look at some of the most common materials and associated internal sound speeds.

 

Material Speed (m / s)

Aluminium 3040 – 6420

Brick 3600 – 4200

Concrete 3200 – 3700

Copper 3560 – 3900

Glass 3950-5000

Iron 3850 – 5130

Lead 1160 – 1320

Steel 4880-5050

Wood 3300-5000

 

After setting it up, the device is ready to measure the sample accurately.

The second step is to determine whether the surface you need to obtain the thickness from is covered by some kind of coating.

What is meant by coating?

Thickness gauge kit

Coating means any material that covers the surface and prevents direct contact between the probe and the surface.

Examples of coatings are:

Dirt
Dust
Rust
Paint
Hairspray, etc.

If you are using a Single Echo device (such as our SA8812 or SAUT160) the layers that cover the surface will cause a discrepancy with the measurements and will give you inaccurate results.

In this scenario, it is important to ensure that the surface is clean and that an insulating gel is used to form a direct connection between the probe and the surface. For devices that can use Echo-Echo and Multiple Echo methods (such as our SAUT310D-SW or SAUT500D-SW), coating is a minor problem and can be overcome.

Echo-Echo allows the ultrasonic thickness gauge to ignore a coating of up to 8 mm thick. The measurement process includes the device that produces an ultrasonic pulse, which is sent through the material you are measuring.

Timing begins when the pulse is initially emitted by the probe and ends when the return echo is detected, which reverberates through the material after bouncing off the bottom wall.

How do the different measurement methods work?

Single Echo is the simplest and as the name suggests, uses a single timing method to measure thickness. This requires a clean sample of the material, which can be difficult to find in many areas outside controlled test environments.

Echo-Echo and Multiple Echo use two and three timers respectively to eliminate the thickness of the coating and obtain an accurate result for the sample thickness.
The second cycle of the sound wave begins at the boundary between the coating and the sample.
This is the key factor to remove the coating from the measurement, because it means that time one and time two will be slightly different.

Multiple Echo has a third timing to use, which increases measurement accuracy when the coating is thicker.
For this, times two and three are usually equal or infinitely different, so that the hardware and computing software can eliminate the coating and record only the thickness of the sample.

PROJECT PSC SRL also uses ultrasonic thickness gauge

Among our numerous customers who use our thickness gauges , Project PSC Srl uses SAMA Tools name-brand for inspections and professional training in the field of non-destructive control.
Project PSC ensures great professionalism, seriousness and efficiency in training, engineering and consulting.

Inspections with the ultrasonic thickness gauge allows one to detect both superficial and deeper defects.

PSC Project Courses and Services

Project PSC is therefore a Center that deals with the training and certification of personnel involved in the execution of Non-destructive Investigations (CND) under the supervision of Bureau Veritas and ACCREDIA.

“Non Destructive Control is the determination of the physical condition of an object made in such a way as not to compromise the functionalities for which the object itself was built.”

ASNT(American Association For Non-Destructive Testing)

Courses are held throughout Italy, even directly on site, with personalized training plans.

It’s also a Testing Laboratory composed of level III technicians who perform preventive (non-destructive and semi-destructive) diagnostic investigations in the field.

So the aim is to detect defects and deficiencies, suggesting targeted interventions, allowing the customer to save time and money.

A summary, the activities carried out involve the following areas:

  • DIAGNOSTICS

    In civil and industrial fields for the maintenance and control of buildings and plants.

  • SEISMIC

    Non-destructive, semi-destructive and destructive tests for the characterization of materials and the definition of seismic risk.

  • TESTS ON STEEL

    Non-destructive testing of welds and steel structures.

  • SECURITY

    Safety checks of structural and non-structural elements.
