Measuring method of ultrasonic thickness measuring instrument. There are five general measurement methods, 30mm multi-point measurement method, accurate measurement method, continuous measurement method, and network measurement method. Each measurement method has its own advantages and application environment, and everyone should choose according to the specific situation. Let us take a look at the measurement method of the ultrasonic thickness measuring instrument.
Ultrasonic thickness measuring instrument measurement method:
General measurement: Use the probe to measure thickness twice at one point. In the two measurements, the split faces of the probe should be 90° each other, and the smaller value is the thickness of the workpiece to be tested.
30mm multi-point measurement method: When the measured value is unstable, take a measurement in a circle with a diameter of about 30mm centering on one measurement point, and take the minimum value as the thickness of the workpiece to be tested.
Accurate measurement
The number of measurements is increased around the specified measurement point, and the thickness variation is represented by an equal thickness line.
Continuous measurement
Continuous measurement along a specified route using a single point measurement with an interval of no more than 5 mm.
Grid measurement
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.
The above content is the measurement method of the ultrasonic thickness measuring instrument, and it is hoped that it will be helpful for everyone's use.
