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: How to calibrate the ultrasonic thickness gauge?

Before measuring the thickness with an ultrasonic thickness gauge, the lower limit and linearity of the instrument should be calibrated. The lower limit of the instrument should be calibrated by a test block whose thickness is the lower limit. If the sound velocity of the material is known, the velocity value of the ultrasonic thickness gauge can be adjusted in advance, and then the test block attached to the instrument can be used for the calibration with the "calibration key" button of the gauge. In fact, it is found that the thickness of the calibration block of different brands of UT thickness gauges is different, so we should pay attention to the thickness of the standard calibration block in the field inspection, so as not to adjust the wrong reference values.

Generally, the calibration test block attached to the ultrasonic thickness gauge is small. When the required thickness deviates from the attached one larger, the step calibration blocks is needed. The ultrasound thickness gauge shall be calibrated with the thickness close to the maximum thickness to be measured and the minimum thickness to be measured respectively (or half of the maximum thickness to be measured).
