Ultrasonic thickness gauge is used to measure the thickness of metal and other materials. They can also measure hardness, elasticity, porosity and other properties.
What You Need to know about ultrasonic thickness gauges
They use high-frequency sound waves to measure the distance between two points on a material.
The gauge sends out a sound wave that bounces off of an object and returns as an echo. The time it takes for the echo to return is measured by electronics in the gauge.
The gauge measures the time it takes for the echo to return and converts this into distance using a formula supplied by its manufacturer. This gives us the thickness value we need in order to take action on our part or make a decision based on what we have measured with our ultrasonic thickness gauge.
Thickness gauges are ideal for measuring very thin, soft materials. These materials include paper, cloth, and cardboard. They do not require physical contact with the object being measured.
The ultrasonic thickness gauge is a device that measures material thickness. It works by sending ultrasonic waves toward the material being measured. The device then measures how long it takes for those waves to return to the sensor. This time difference helps calculate the material’s thickness.
You can use the ultrasonic thickness gauge for various purposes. People commonly use it for testing metal sheets, pipes, square metal tubes, rods, and more. Many industries use this device. These industries include aerospace, automotive, and consumer goods.
How does it work?
The ultrasonic gauge sends out ultrasonic waves. It measures how long it takes for the waves to return to the sensor. The waves bounce off the object being measured. This time difference helps calculate the object’s thickness. The ultrasonic waves travel through air at about 340 meters per second (m/s), which means that if an object is 10 mm thick then it would take approximately 3 milliseconds (ms) for an ultrasound wave to travel through it and come back. So, if an ultrasonic wave leaves a sensor at t=0 seconds and comes back at t=3ms then its distance traveled.
The ultrasonic wave is transmitted through a small “sensor” or “horn” on the transducer head. The wave travels at high speed through the material. It reflects back to the transducer head. The time it takes for this reflection to occur determines how thick the material is. The transducer calculates this time, converts it into distance and displays it as an image or numeric readout on its display screen.
Ultrasonic thickness gauges can be used for many different materials, including plastics, wood, ceramics and metals. If you need to measure something that isn’t solid or doesn’t have a clear boundary between the top surface of your object and its bottom surface (such as paper), then you should use an ultrasound scanner instead of an ultrasonic gauge because they can penetrate materials that would be too thick for an ordinary gauge to accurately measure using its sonic waves alone.
The ultrasonic thickness gauge is a non-destructive testing instrument. This means it does not damage the surface of the material being tested. You can use this device on many different types of materials, such as:
- Steel
- Aluminum
- Brass
- Copper
- Bronze
- Stainless steel
You can use ultrasonic thickness gauges in many different industries, including:
- Automotive industry: To measure gaps between parts or components such as bearing races, bushings, gears, shafts, and flywheels
- Manufacturing industry: To measure gaps between parts or components such as bushings, bearings, gears, and shafts
- Metrology industry: To measure gaps between parts or components such as bushings and bearings
- Construction industry: To measure gaps between parts or components such as bushings and bearings
An ultrasonic thickness gauge uses sound waves reflected off a surface to determine its thickness.
The depth of penetration depends on the frequency used. It also depends on the material being tested. To get an accurate reading, start with a known surface profile. Cut the profile from your material in advance. Use it as a reference for your measurements.
Ultrasonic thickness gauges measure the thickness of various materials. These materials include metals, plastics, and liquids such as oil or water.
You simply place the probe tip against your material and push down gently until you see an echo return on your display screen. You can also use additional probes in order to measure multiple areas quickly and easily with one tool.
The ultrasonic thickness gauge has many benefits over other types of gauges, including:
- It’s fast: Ultrasonic thickness gauges are able to calculate the thickness of an object in just seconds, whereas other types of gauges may take up to several minutes or even hours;
- It’s accurate: Ultrasonic thickness gauges are extremely accurate when compared with other types of gauges;
- It’s non-destructive: Ultrasonic thickness gauges do not affect the material being measured. This is different from other methods, such as electrical resistance or laser testing.
