An ultrasonic thickness gauge is a device that employs ultrasonic waves to measure the thickness of an object.
It determines the thickness by measuring the time ultrasonic waves take to traverse the object. This non-destructive method is ideal for product and material quality control. The gauges are highly accurate, capable of detecting minute thickness variations and measuring the thickness of thin materials efficiently.
The operation typically involves pressing the device against the object's surface and activating the measurement button. Many models boast digital displays and automated measurement functions. Their portability makes them suitable for on-site usage, and their compact design allows for measurements at various locations.
Ultrasonic thickness gauges find applications in various scenarios where thickness measurement is essential.
In the manufacturing sector, these gauges are crucial for measuring the thickness of materials such as steel plates and aluminum plates. They are instrumental in ensuring precision in products like automotive body panels and aircraft frames.
In the construction field, these gauges are employed to measure the thickness of concrete in structures and floors, aiding in strength assessment and uniformity checks. They are also invaluable for detecting corrosion in metals, especially in areas like underground piping or building interiors, as they measure thickness reduction non-destructively.
Ultrasonic thickness gauges operate on the principle of measuring an object's thickness using the travel time of ultrasonic waves. The gauge comprises an ultrasonic generator, usually made of piezoelectric or magnetic elements, transforming electrical energy into ultrasonic waves.
These waves are emitted towards the object, where they are reflected and scattered by the internal structure and interfaces. The reflected waves are then captured by a receiver, transformed back into electrical signals, and their travel time is measured.
The calculation unit computes this travel time. With pre-set ultrasonic wave velocity data for the specific material, it calculates the object's thickness. Accurate velocity data is crucial, as ultrasonic wave speed varies with the material's composition and density.
Different types of ultrasonic thickness gauges are designed for specific applications:
This gauge utilizes a single transmitter/receiver element, making it suitable for simple thickness measurements in thinner materials.
With separate transmitter and receiver elements, this gauge offers enhanced signal accuracy and sensitivity, applicable to various uses.

This type has both transmitter and receiver elements in the same sensor head, ensuring more accurate measurements, particularly under high-temperature conditions and on uneven surfaces.
This gauge features multiple transmitting and receiving elements, allowing for thickness measurements on complex surfaces and shapes.
Consider the following aspects when choosing an ultrasonic thickness gauge:
Reflect on the material type and surface condition of the object. Specific materials and shapes might necessitate specialized gauges.
Evaluate the range of thickness to be measured and the precision needed. Gauges vary in their capacity to measure ultra-thin or thick materials.
Usability is crucial. Consider features like user-friendly interfaces, simple navigation, and data recording functions.
1. Large range: The instrument can measure the thickness of materials up to 600mm, which can meet the measurement needs of most users.
2. High precision: The instrument has high testing precision, up to ±0.05mm, ensuring that it can pass the testing of the national authoritative metrology institute.
3. High-definition display: The instrument adopts LCD high-definition display, and the readings are clear under the backlight environment.
4. Automatic gain: Automatically select the appropriate gain according to the material type and thickness to achieve the best measurement effect.
5. QC mode: QC function can determine whether the incoming material is qualified according to the set upper and lower limits, to achieve rapid inspection of incoming material.
6. Statistical function: Automatically count the maximum, minimum and average values of the 9 recently measured measurement values.
7. Adjust sound speed: It can be used in 3 kinds of setting sound velocity, which select sound velocity for known material/ set sound velocity for known thickness/ manual setting sound velocity.
8. Comfortable grip: It has comfortable grip and easy to operate with ergonomic design.
