There Are Several Methods For Measuring Ultrasonic Thickness Gauges.
Nov 16, 2018

There are several methods for measuring ultrasonic thickness gauges.


Let's take a look at the following small series. There are several ways to measure the ultrasonic thickness gauge.


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


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, 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.


4. General measurement methods:


(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 minimum value is the thickness value of the workpiece to be tested.
