Publish Time: 2025-01-21
Digital coating thickness gauges usually have multiple measurement modes to adapt to different application scenarios and measurement requirements.
1. Common measurement modes
Single point measurement mode: This is the most common measurement mode, which is used to quickly obtain the coating thickness at a single location. The user only needs to place the sensor on the surface to be measured to obtain the measurement results immediately.
Continuous measurement mode: In this mode, the instrument continuously obtains data from multiple measurement points at a certain frequency, which is suitable for situations where a large area needs to be scanned quickly. The continuous measurement mode can provide the distribution of coating thickness.
Average measurement mode: In this mode, the instrument averages multiple measurement data to reduce the possible errors in a single measurement and improve the accuracy and reliability of the measurement results.
2. Measurement modes suitable for different materials
Magnetic measurement mode: Suitable for measuring the thickness of non-magnetic coatings on ferromagnetic substrates, such as paint and galvanized layers on iron or steel surfaces. This mode uses the principle of magnetism to determine the coating thickness by measuring the change in magnetic force.
Eddy current measurement mode: Suitable for measuring the thickness of non-conductive coatings on non-ferromagnetic substrates, such as paint and anodized layers on metal surfaces such as aluminum and copper. The eddy current measurement mode uses the eddy current induction principle to determine the coating thickness by measuring the eddy current changes.
Ultrasonic measurement mode: Suitable for measuring the coating thickness on a variety of substrates, especially composite materials or multi-layer coatings. The ultrasonic measurement mode uses the difference in the propagation speed of ultrasonic waves in different media to determine the coating thickness.
3. Automatic identification mode
Automatic detection of substrate type: Some high-end digital coating thickness gauges have the function of automatically identifying the substrate type, and can automatically select the appropriate measurement mode according to the magnetic or non-magnetic properties of the substrate, simplifying the operation steps.
Intelligent adjustment of measurement parameters: In the automatic identification mode, the instrument will automatically adjust the measurement parameters, such as measurement frequency, gain, etc., according to the characteristics of the substrate and coating to ensure the accuracy of the measurement results.
4. Data processing and display mode
Real-time data display: The instrument can display the current measurement data in real time and switch the display mode as needed, such as single-point measurement value, continuous measurement value or average measurement value.
Data storage and export: Supports data storage function, users can store the measurement data inside the instrument or export it to the computer through the USB interface for subsequent analysis and processing.
Statistical analysis mode: Provides statistical analysis functions, such as maximum value, minimum value, average value, standard deviation, etc., to help users fully understand the distribution of coating thickness.
5. Calibration and verification mode
Automatic calibration mode: Some instruments have automatic calibration function, which can automatically perform zero point calibration and full scale calibration to ensure measurement accuracy.
Manual calibration mode: Provides manual calibration options, and users can manually adjust the calibration parameters of the instrument as needed to adapt to different measurement needs.
Calibration verification mode: Supports calibration verification function, and users can use standard samples to verify the measurement accuracy of the instrument to ensure the reliability of the measurement results.
6. Other special modes
Remote measurement mode: Some high-end instruments support remote measurement function, and users can transmit measurement data to remote devices through wireless communication technology (such as Bluetooth or Wi-Fi) to achieve remote monitoring and operation.
Multi-language mode: Supports multiple language interfaces, which is convenient for users in different countries and regions.
The digital coating thickness gauge can meet the measurement needs of different materials and application scenarios through multiple measurement modes, such as single point measurement, continuous measurement, average measurement, magnetic measurement, eddy current measurement, ultrasonic measurement, etc. The addition of functions such as automatic identification, data processing, calibration and verification further improves the intelligence and convenience of the instrument.
