Function Comparison

Q1: What is an ultrasonic thickness gauge?
The ultrasonic thickness gauge is improved based on the principle of ultrasonic measurement. It can measure the thickness of metals and other materials and can measure the sound speed of the material. The sisco ultrasonic thickness gauge is a portable thickness meter that can measure the thickness of various pipes and pressure vessels in production equipment, as well as accurately measure various sheets and machined parts.

Q2: How does an ultrasonic thickness gauge work?
sisco ultrasonic thickness gauge offers through-coating thickness measuring capability. It measures the thickness of an object by precisely calculating the times the probe sends an ultrasonic pulse to the object and passes through the object until the probe receives the reflection from the boundary. The ultrasonic pipe thickness gauge adopts the most advanced microprocessor and ultrasonic technology and has the characteristics of zero drift, reliable and stable reading, and no need for zero calibration. You can now test painted objects without removing paint or correcting paint thickness.

Q3: 4 Measurement methods of ultrasound thickness gauge

• Single-point measurement method: It means that the ultrasound thickness gauge is used to measure any point of the measured material with a probe, and the display value is the thickness value.
• Two-point measurement method: The ultrasound thickness meter is used to make two measurements at the same point of the measured material with a probe. In the second measurement, the probe's split surface is 90 degrees, and the smaller value in the two measurements is the thickness value.
• Multi-point measurement method: When the measurement value is unstable, take a measuring point as the center and make multiple measurements in a circle with a diameter of about 30 mm. The minimum value is the thickness value.
• Continuous measurement method: It uses a single-point measurement method to measure continuously along a designated line with an interval of not less than 5 mm. The minimum value is the thickness value.

Tips: What affects the accuracy of an ultrasonic thickness gauge?

1. Sound speed. For occasions where the requirements for measurement results are not high, the speed of sound found from various data can be used for measurement, but the speed of sound found from various data is often significantly different from the actual sound speed of the material. The accurate measurement method is to take a standard sample that is exactly the same as the material to be tested. The standard sample is required to be flat and smooth, and the same thickness as the maximum thickness of the tested sample to determine the sound velocity of the material.
2. Ultrasonic thickness gauges probe selection. In general, the sound velocity in solid material decreases with the increase in temperature, so a special probe for a high-temperature sample should be used. When an ultrasonic wave passes through the casting and austenitic steel, the scattering attenuation will be serious due to the uneven structure or the bulky grain, which may make the echo obliteration, resulting in no display. Therefore, it is recommended to choose the coarse crystal special probe with a lower frequency (2.5 MHz). The radius of curvature of the workpiece is too small, especially when measuring the thickness of a small-diameter tube. Since the surface of the probe is usually flat and the contact with the surface is point contact or line contact, the transmission of sound intensity is low (the coupling is not good), the special probe with a small diameter can be selected (6mm).
3. Ultrasonic thickness gauge calibration. Both the probe and the circuit have a certain signal transmission time, which must be subtracted from the total transmission time. This process is called instrument calibration. Ignoring this step will cause a large error in the measurement result. During calibration, press the calibration key of the ultrasonic thickness gauge, apply a little couplant to the probe and lightly press it on the calibration test block that comes with the instrument. When the instrument displays the thickness value of the standard test block indicated in the manual, the calibration is completed. After replacing the battery and probe of the ultrasonic thickness gauge, and before each measurement, it should be calibrated.
