How coating thickness gauges and ultrasonic thickness gauges differ
The ultrasonic thickness gauge measures the thickness according to the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the interface of the material, the pulse is reflected back to the probe to determine the thickness by measuring the propagation time of the ultrasonic wave in the material. Measure the thickness of the material.
Coating thickness gauges and ultrasonic thickness gauges are both instruments used to measure the thickness of objects, but coating thickness gauges and ultrasonic thickness gauges have many differences in the measurement process, such as measurement objects, measurement thickness and other factors. The following Zhuhai Tianchuang Instrument Co., Ltd. will briefly introduce the differences between coating thickness gauges and ultrasonic thickness gauges.
The difference between coating thickness gauge and ultrasonic thickness gauge:
Coating thickness gauges are mainly used in the surface treatment industry to measure the coating thickness on metal or plastic surfaces. The specific measurement method is as follows: put the ordinary coating thickness gauge diaphragm (calibration sheet) together with the product that has not undergone surface treatment, and then spray, and measure the thickness of the diaphragm with an instrument after the end, so as to know the thickness of the product coating .
