    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: Why do ultrasonic thickness gauges need couplant?

    In order to improve the sound energy transmission between the probe of ultrasonic thickness gauge and the workpiece, a thin layer of liquid applied between the probe and the detection surface is called a couplant.

    When there is a layer of air between the probe of ultrasonic thickness gauge and the workpiece, the reflectivity of the ultrasonic wave is almost 100%. Even a thin layer of air can prevent the ultrasonic wave from entering the workpiece. Therefore, it is very important to remove the air between the probe and the workpiece. The coupling agent can fill the air gap between the probe and the workpiece, so that ultrasound can be transmitted to the workpiece, which is the main purpose of using the couplant. In addition, the couplant also has a lubrication effect, which can reduce the friction between the probe of ultrasonic thickness gauge and the workpiece, prevent the workpiece surface from wearing the probe, and make the probe easy to move.

    According to the surface condition and acoustic impedance of the workpiece to be tested, the coupling agents without bubbles and suitable viscosity should be selected, such as glycerin, oil, silica gel, water glass and paste, high temperature coupling agent, etc. If the surface of the workpiece is rough, the thicker coupling agent should be chosen. The coupling agents specially used for thickness measurement can also be used. In practical use, it is necessary to keep the coupling agent clean, not to make it stained, or it will affect the accuracy of the measurement of ultrasonic thickness gauge.
