Electronic thickness gauge is an instrument used to measure the thickness of materials and objects, widely used in industrial production. It can measure the thickness of various materials through different principles and techniques, such as ultrasound, magnetism, eddy current, isotopes, etc.
Classification and principles
Electronic thickness gauges can be classified into various types based on different measurement principles:
Ultrasonic thickness gauge: Uses the principle of ultrasonic pulse reflection to measure thickness.
Magnetic thickness gauge: Calculates the thickness of the covering layer by measuring the change in magnetic resistance.
Eddy current thickness gauge: Uses the eddy current generated by a high-frequency magnetic field inside the metal body to measure the thickness of the covering layer.
Radioactive thickness gauge: Measures thickness using the penetration characteristics of alpha rays, beta rays, and gamma rays.
Contact thickness gauge: Directly contact the surface of the material for measurement.
Application area
Electronic thickness gauges are widely used in multiple industries, including:
Metal industry: Used to measure the thickness of steel plates.
Plastic industry: Used to measure the thickness of materials such as film and paper.
Electric power industry: Used to measure the thickness of boiler drums, heating surface pipes, pipelines, etc.
Automotive industry: Used to measure the thickness of coatings or plating, ensuring the smoothness and stability of the paint surface.
Characteristics and advantages
Electronic thickness gauges have the following characteristics:
Multiple types of selection: Choose the appropriate thickness gauge based on different materials and measurement needs.
High precision measurement: Some thickness gauges have high-precision measurement capabilities, suitable for various complex measurement needs.
Non destructive measurement: Some types of thickness gauges use non-destructive measurement methods that do not cause damage to the material itself.
Data storage and analysis: Some thickness gauges have functions such as data storage, statistics, and analysis, which facilitate data management and quality control.
