    What are the factors that affect the measurement of the ultrasonic thickness gauge? (1)

    (1) The surface roughness of the workpiece is too large, which is resulting in the poor coupling between the probe and the contact surface, low reflection echo, and even failure to receive the echo signal. For surface rust, in-service equipment, pipes, etc., anodizing coating thickness gauges have e

    What are the factors that affect the measurement of the ultrasonic thickness gauge?(2)

    (9) The effect of temperature. Generally, the speed of sound in the solid materials decreases with the increasing temperature. Test data shows that for every 100 °C increase in hot material, the speed of sound drops by 1%. For high temperature in-service equipment.This is often the case. High-temper

    The Difference Between the Magnetic Induction Thickness Gauge and the Eddy Current Principle Thickness Gauge

    The principle of magnetic induction is to measure the thickness of the coating by using the magnetic flux of the probe through the non-ferromagnetic coating into the iron substrate. The thicker coating, the smaller is the magnetic flux. Because it is an electronic instrument, it is easy to calibrate

    Measuring principle and method of coating thickness gauge

    Principle of magnetic attraction force measurementThe amount of suction between the permanent magnet (probe) and the magnetically permeable steel is proportional to the distance between the two, which is the thickness of the coating. Using this principle to make a thickness gauge, measurement can be

    Classification of coating thickness measurement gauge (2)

    The high frequency AC signal generates an electromagnetic field in the probe coil, and a vortex is formed therein when the probe is close to the conductor. The closer the probe is to the conductive to substrate, the larger the eddy current and the greater the reflection impedance. This feedback acti
