The quality requirements for electronic thickness gauges mainly include the following aspects:
Measurement accuracy: The measurement accuracy of electronic thickness gauges is one of the key quality indicators. For example, the measurement accuracy of eddy current thickness gauge is ± (1-3% h+1 μ m), and the indication error of magnetic resistance thickness gauge is ± (1-3% h+1 μ m).
Resolution: High resolution can provide more accurate measurement results. For example, the resolution of an eddy current thickness gauge is 1 μ m.
Measurement range: Different thickness gauges have different measurement ranges. For example, the measurement range of eddy current thickness gauge is 0-1200 μ m, while the measurement range of magnetoresistance thickness gauge is 0-1200 μ m.
Usage environment: The usage environment of the thickness gauge also has an impact on its quality. For example, the operating environment temperature of the eddy current thickness gauge is 0 ℃ to 40 ℃, and the relative humidity is not greater than a certain value.
Display function: Some advanced thickness gauges can display the average, maximum, minimum, standard deviation, and number of measurements taken, as well as indicate the working status and battery usage of the instrument.
Power requirements: For example, the eddy current thickness gauge uses one 6f22 9v battery.
External dimensions and quality: For example, the external dimensions of an eddy current thickness gauge are 160mm × 80mm × 30mm, with a mass of approximately 250g.
