Ultrasonic Thickness Gauge

For detailed information on ultrasonic thickness gauges:

Storage Capacity: Generally, ultrasonic thickness gauges have a storage capacity of 6 groups, with each group capable of storing 100 measurement points, totaling 600 measurement points.

* Dimensions and Weight: The dimensions and weight of the ultrasonic thickness gauge vary by brand and model. Generally, the dimensions are 146mm * 81mm * 30mm, and the weight is approximately 300g (including battery).

* Power Supply: Ultrasonic thickness gauges typically use two AA batteries as the power source.

* Optional Probes: Ultrasonic thickness gauges of different models may be equipped with various probes for convenience, catering to diverse measurement requirements. For instance, certain models may come with probes such as PT-08, PT-06, PT-04, PT-10, ZT-12, GT-12, E-E10, etc.

In summary, the portable coating ultrasonic thickness gauge is a highly practical tool, capable of measuring the thickness of various materials with high precision.

Ultrasonic Thickness Gauge

Incorrect sound velocity selection. Pre-set the sound velocity for the material type before measuring the workpiece, or measure the sound velocity by using a standard block. Incorrect results will occur when measuring a different material after calibrating the instrument with one material (commonly using steel as a test block). It is required to correctly identify the material and select the appropriate sound velocity before measurement.

The Influence of Stress. Most in-service equipment and pipelines have stress present. The stress condition of solid materials has an impact on the speed of sound. When the stress direction is consistent with the propagation direction, if the stress is compressive, the stress causes the workpiece to become more elastic, increasing the speed of sound; conversely, if the stress is tensile, the speed of sound slows down. When the stress is not consistent with the propagation direction of the wave, the vibration path of the particles in the wave process is disturbed by the stress, causing the propagation direction of the wave to deviate. According to the data, generally, as stress increases, the speed of sound increases slowly.

The impact of metal surface oxides or paint coatings. Dense oxides or protective paint layers formed on the metal surface, although tightly bonded to the base material and with no apparent interface, the ultrasonic thickness gauge company for portable coatings, the speed of sound propagation in these two substances is different, resulting in errors. Additionally, the magnitude of the error varies with the thickness of the coating.

Wood coating applications are quite clear to most. For instance, coatings on furniture, which are generally not measurable by standard magnetic induction thickness gauges or eddy current meters.

Traditional methods involve using destructive thickness gauges, but destructive testing is not feasible in practical applications, especially during certain inspection stages of finished products.

At this point, this coating thickness gauge for measuring wood is a good choice. This gauge is relatively simple to use for measurements, and most applications do not require calibration. Moreover, its detection is quite accurate.

It measures using the principle of ultrasonic technology, and the high-grade version can measure up to 3 layers of coating on the base material, with built-in graphic analysis. This coating thickness gauge has a measuring range of 1M, which is one thousand micrometers.

But it has a rather stringent requirement: the coating's measured thickness must be over 13μm, with an accuracy of ±3%. Remember, that ±3%. Although it may not seem as high as the precision of domestic products, this one comes with a certificate traceable to NIST or PTB, meaning it comes with an American certificate; it's not just talk.
