Features of Powder Coat Thickness Gauges
Friends who have related work experience know that the powder coating thickness gauge can complete the non-destructive coating thickness measurement on metal surface such as steel. Although the specifications are slightly different, overall, because of small measurement errors. The instrument is widely used in processing and other related industries due to its high reliability and high stability. You can choose the most suitable instrument according to the specific workpiece to be measured.
Although there are different types of powder coat thickness gauges, high-quality instruments have some common characteristics. The most basic is zero-position stability, that is, no matter what kind of powder coat thickness gauge is, it must be calibrated to zero.
1. Powder coating thickness gauge features
The stability of the zero position is the fundamental guarantee for the accuracy of the measurement results. High-quality powder coat thickness gauges can maintain zero position for a long time after calibration and complete accurate measurement.
The second is temperature compensation. The measurement of the thickness of many workpieces will be affected by external factors such as temperature. Measurement in different environments is prone to errors. Therefore, most high-quality powder coat thickness gauges have temperature compensation function, which can better ensure that accurate measurement results can be obtained under different temperature environments.
The third is linear editing. If the powder coat thickness gauge does not come with a linear editing function, the measurement repeatability error will be relatively large, so you must choose an instrument that has been added to the linear editing to improve the measurement accuracy and ensure its repeatability.
In addition, we will share some points on the use of powder coat thickness gauges. Although the measurement principles are slightly different, the operation points during the instrument measurement are generally the same.
2. How to measure coating thickness?
Step 1: Press the "Power" button to turn on the gauge. The display screen will light up after the machine is turned on and the buzzer will start to work. Once the power shortage occurs, there will be a low battery alarm. If the probe is not placed securely, it will cause a large deviation between the measurement result and the actual value, so please pay attention to it. Be sure to press the probe vertically on the measured surface.
Step 2: Perform calibration, integrating single-point and multi-point calibration methods. After accurate calibration is completed, the measurement results can be better guaranteed and the measured values can be controlled within a reasonable error range.
Step 3: According to different measurement needs, choose the most suitable mode. However, because the powder coat thickness gauge measures the difference of the substrate, the user should pay attention to selecting the most suitable probe and do not confuse the operation. And it is recommended to perform several measurement operations at one point and improve the accuracy of the measurement results by averaging.
In summary, mastering the correct method of how to use the powder coat thickness gauge and understanding its related characteristics can ensure that everyone can use the equipment more scientifically and correctly in actual operation and get relatively more accurate measurement results.
