What Are The Measurement Methods Of Ultrasonic Thickness Gauges
Nov 27, 2018

What are the measurement methods of ultrasonic thickness gauges?

Let's take a look at the following small series. What are the measurement methods for ultrasonic thickness gauges?

1, the general measurement method:

(1) Perform the thickness measurement twice with the probe at one point. In the two measurements, the split faces of the probes should be 90° each other, and the smaller value is the thickness of the workpiece to be tested.

(2) 30mm multi-point measurement method: When the measured value is unstable, a plurality of measurements are made in a circle having a diameter of about 30 mm centering on one measurement point, and the small value of zui is taken as the thickness value of the workpiece to be tested.

2. Accurate measurement method: increase the number of measurements around the specified measurement points, and the thickness change is indicated by the thick line.

3. Continuous measurement method: continuous measurement along the specified route by single point measurement method, the interval is not more than 5mm.

4, grid measurement method: draw a grid in the specified area, according to the point thickness record. This method is widely used in corrosion monitoring of high pressure equipment and stainless steel lining.
