UM-4 series thickness gauge Features: 1. Economical all-digital thickness gauge The all-digital thickness gauge needs to convert the analog ultrasonic signal into a digital signal, and then perform arithmetic processing on the digital signal to finally obtain high-performance thickness measurement capability. The UM-4 series' A-scan snapshot function, zero-crossing measurement technology, and high resolution are all based on all-digital technology. 2. The innovative A-scan snapshot function marks the entry of the economical thickness gauge into the all-digital era. The UM-4 is the first in its class to offer A-scan waveform display. The sonic wave is no longer an invisible abstract concept. The user can directly see the ultrasonic signal waveform on the screen to verify whether the thickness reading is correct, analyze the cause of the problem, and help the user find a solution to the problem. 3. Using breakthrough zero-crossing measurement technology Based on all-digital technology, using zero-crossing measurement technology, thickness measurement values are not affected by echo intensity, material attenuation coefficient, gain and gate height, and have high measurement stability and reliability. 4. With penetrating coating function We have previously introduced the UM-1D Thickness Gauge with Penetration Coating Technology, and now the UM-4D has the same acclaimed features as the UM-4DL. This function is achieved by measuring two consecutive bottom surface echoes of the substrate. In this mode, there are more advantages: zero-free calibration; high stability, measured values are not affected by probe pressure, coupling layer thickness and dust stains on the workpiece surface; zero drift. 5. More useful features Gain: high, medium and low three adjustable; Alarm mode: dynamically change the thickness of the thickness reading during an alarm; Difference/Reduction Rate: The difference mode displays the difference in the difference between the measured thickness and the preset thickness. The reduction rate is a percentage calculated by the thickness reduction after the material is thinned. Typical applications are measurements of metallic materials that are thinned by bending; Maximum/minimum capture: The current thickness value, minimum thickness value, and maximum thickness value are simultaneously displayed on the screen.
