One of the most common questions when choosing an ultrasonic thickness gauge is:
“Can this instrument measure my material?”
The Wintact WT-100A Ultrasonic Thickness Gauge works by transmitting ultrasonic sound through a material and calculating thickness based on the travel time of the ultrasonic signal and the selected sound velocity.
Because different materials transmit sound differently, understanding the material is essential before taking measurements.
What Types of Materials Can Be Measured?
Ultrasonic thickness measurement is generally suitable for homogeneous materials that can transmit ultrasonic energy effectively.
Depending on the material condition, geometry and measurement requirements, applications may include materials such as:
Steel
Stainless steel
Aluminium
Copper
Brass
Cast iron
Certain plastics
Glass
Other suitable solid materials
Not every material or component is equally easy to measure. Surface condition, internal structure and geometry can significantly affect measurement quality.
Measuring Steel
Steel is one of the most common applications for ultrasonic thickness gauges.
Typical examples include:
Steel plates
Pipelines
Storage tanks
Pressure vessels
Fabricated structures
Boiler-related components
Machinery
Marine structures
This is why ultrasonic thickness gauges are commonly found in maintenance departments, fabrication workshops and industrial inspection work.
Measuring Stainless Steel
Stainless steel is widely used in:
Food processing
Chemical plants
Pharmaceutical facilities
Manufacturing
Tanks
Process piping
Industrial machinery
When measuring stainless steel, the appropriate sound velocity should be used rather than assuming that every metal uses the same setting.
Measuring Aluminium
Ultrasonic thickness measurement may also be performed on suitable aluminium components.
Applications can include:
Aluminium plates
Fabricated components
Industrial parts
Selected marine components
Manufacturing QC
Because aluminium has different acoustic properties from steel, the instrument must be configured appropriately.
Can WT-100A Measure Plastic?
Certain plastics can be measured ultrasonically, but results depend heavily on the type of plastic, material structure, thickness and surface condition.
Before purchasing an instrument specifically for plastic measurement, it is advisable to identify the exact material and expected thickness.
A sample measurement may be useful for unusual materials or demanding applications.
Can It Measure Glass?
Suitable glass materials may allow ultrasonic thickness measurement, but the application should be evaluated carefully.
Glass geometry, surface condition and material properties can affect the measurement.
For specialised glass inspection, customers should confirm their exact application rather than assuming all glass products can be measured identically.
Why Does Sound Velocity Matter?
This is one of the most important concepts in ultrasonic thickness measurement.
The instrument calculates thickness using the relationship between:
Ultrasonic Travel Time + Material Sound Velocity = Thickness
If the sound velocity is incorrect, the calculated thickness will also be incorrect.
For example, using a steel setting to measure a different material can produce a stable-looking reading that is nevertheless inaccurate.
A stable display does not automatically mean the measurement is correct.
Can It Measure Multi-Layer Materials?
Users should be careful with multi-layer or composite structures.
Examples include:
Metal + coating
Laminated materials
Bonded layers
Composite panels
Materials containing internal gaps
Ultrasonic signals can behave differently at boundaries between different materials.
A conventional thickness gauge should therefore not automatically be assumed to provide the thickness of a specific layer within a multi-layer structure.
Specialised equipment or measurement techniques may be required.
What About Rough or Corroded Materials?
A heavily corroded surface can make ultrasonic measurement more difficult.
Possible problems include:
Poor probe contact
Unstable readings
Difficulty obtaining an ultrasonic echo
Local thickness variation
Surface pits
Surface preparation and multiple measurement points may be required.
For serious corrosion assessment, a single measurement should not be treated as a complete evaluation of the component.
How Do I Know Whether WT-100A Is Suitable for My Application?
Before selecting an ultrasonic thickness gauge, answer four questions:
1. What material are you measuring?
Steel, stainless steel, aluminium, plastic or something else?
2. What is the approximate thickness?
Knowing the expected range helps determine whether the instrument and probe are suitable.
3. What is the shape of the component?
Plate, pipe, tank, vessel or small component?
4. What is the purpose of the measurement?
Incoming QC, fabrication, corrosion monitoring, preventive maintenance or another application?
These questions are often more important than simply asking:
“Which thickness gauge is cheapest?”
