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

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

5 aspects to consider when selecting 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 result of your Quality Control (QC) and your Quality Assurance (QA) activities.

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

It is a supplier that operates all over the world through its own SAMA Tools brand.

I believe it is reliable and experienced, from which you can make sure you get hight quality tools.

Moreover, all their instruments are manufactured to comply with the relevant standards.

2. Calibration

As defined by the experts at SAMA Tools, “calibration means to identify metrological characteristics of a measuring instrument and it may be defined as a “photograph” of the instrument in its current state. It is the result of a comparison with a reference sample and it does not contemplate the adjustment of the instrument.”

This is an important aspect because it can happen that you get a “quality” instrument but which is not calibrated, so it may need adjustment. The result is an instrument that does not work properly and it will only create problems.

To prevent this from happening, SAMA Tools 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 already own and of other brands.

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

3. Destructive or non-destructive testing instruments?

When we speak about measuring and control instruments, we can speak about two categories: destructive testing instruments and non-destructive testing instruments.

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

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

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

This will allow you to identify properties and mechanical features directly 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 repair. However, the technical support you should look for when selecting your measuring and control instruments provider must be a more holistic kind of service.

As SAMA Tools Export Manager Martina Guatteri, expresses it: “It is well known that every successful company has an excellent after-sales assistance.” Yes, this should be part of what you should look for, but as she also says, pre-sales assistance is also very important.

The goal is to find a supplier that can really understand your needs and provide you with the best solution, instead of having to be adjusting until you get “something close to what you wanted”.

Moreover, having a good technical support means making sure you won’t have any problems while using the instruments, and that you won’t need a long time to learn how the instrument is used.

SAMA Tools offers all their customers a holistic metrological consultancy service and they take care of your needs from the very beginning. They help you become an independent user of their instruments, with expert technicians that will assist you during installation, if required, and during the first measurements. And you will gain notions that go far beyond reading a manual.

5. Do you need portable instruments?

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

SAMA Tools can provide you with a wide range of portable tools while maintaining the highest quality on the market.

Feedback from the world

Below you can find some feedback that we recently received from three clients based outside Italy.

The first one is a video review that sent us Emre Sari of Sarilar Dis Tic Ltd Sti, a company based in Turkey that provides highest quality hazelnuts.

To ensure the high quality of their hazelnuts, they constantly monitor the humidity level, using our Moistures meters – SA7825G.

In addition, Sarilar has assumed the role of supplier of SAMA Tools brand, providing these moistures meters to its customers on the Turkish territory, for a better quality control of their final products.

Listen to the video review, or read the transcription below, and if you want to know more, read:

“Quality Control in the Hazelnut Production: The case of Sarilar”

 

The second feedback comes from Spain, from a company certified for the production of Flow meters.

“Very good service and counseling during the purchase. The instrument working as expected without any problems.”

Marcel Caballero – Guadarrama-Flow, S.L.

 

The third one comes from Romania, from a company in the metal packaging sector. It provides solutions to some of the world’s most recognizable brands.

“For several years we were looking for an equipment to improve our quality incoming goods system. We faced issues with the curing of the lacquer on our raw material sheets for which was difficult to prove the cause of the nonconformity. By using SAAB521 Solvent Rub Resistance Tester we succeeded to have the expected results, to put in place a procedure and more than that extended it to our suppliers in order to have the same measurement system. I highly recommend it.”

Are you looking for information on how to use an ultrasonic thickness gauge to measure the thickness of a 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.
