Ultrasonic thickness gauge use method

Let's take a look at the following small series, how to use the ultrasonic thickness gauge

☆ General measurement

1. Use the probe to measure the thickness twice 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, take a measurement point as the center, and perform multiple measurements in a circle with a diameter of about 30mm, taking the small value of zui as the measured workpiece thickness value [2].

☆ Accurate measurement

The number of measurements is increased around the specified measurement point, and the thickness change is indicated by an equal thickness line.

☆ Continuous measurement method

Continuous measurement along a specified route using a single point measurement with an interval of no more than 5 mm.

☆ Grid measurement method

Mark the grid in the specified area and record the thickness by point. This method is widely used in corrosion monitoring of high pressure equipment and stainless steel lining.
