Ultrasonic thickness gauge is used to measure the thickness of metal and other materials. They can also measure hardness, elasticity, porosity and other properties.
Here are some things 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.
Ultrasonic thickness gauges are ideal for measuring very thin soft materials such as paper, cloth and cardboard because they do not require physical contact with the object being measured.
Ultrasonic thickness gauge is a device that measures the thickness of materials. It works by sending ultrasonic waves towards the material being measured and then measuring how long it takes for those waves to return to the sensor. This time difference is used to calculate the thickness of the material.
Ultrasonic thickness gauge can be used for a variety of purposes such as testing metal sheets, pipes, square metal tubes, rods, etc. It is also used in many industries like aerospace, automotive, consumer goods, etc.
How does it work?
The ultrasonic gauge sends out ultrasonic waves and then measures how long it takes for them to return back to the sensor after bouncing off the object being measured. This time difference is used to 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 “tissue” probe or “horn” on the transducer head. The wave travels at high speed through the material being measured and is reflected 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, which means it does not damage the surface of material being tested. This device can be used on many different types of materials such as:
- Steel
- Aluminum
- Brass
- Copper
- Bronze
- Stainless steel
- Ultrasonic thickness gauges can be used 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 and the material being tested. To get an accurate reading, start with a known surface profile that has been cut from your material in advance so you can use it as a reference for your measurements.
Ultrasonic thickness gauges can be used to measure the thickness of a variety of different materials including 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 don’t have any effect on the material being measured, unlike other methods such as electrical resistance or laser testing.
