Digital ultrasonic thickness gauge, offers high precision thickness testing of thin materials, like sheet metal, sheet steel,
SKU: CHN-PM-5
Free Shipping Worldwide
Delivery date: 6-12 days

Digital ultrasonic thickness gauge is high precision with 0.001mm resolution, especially suitable for the thickness measurement of thin-walled materials, like car body sheet, fire/security doors and extinguisher, etc.

Features

  • High resolution 0.001mm
  • Real-time A-Scan with adjustable gain, range, blanking, etc.
  • Designed for thin workpiece, with lower measurement limit to 0.2mm
  • 2.4" QVGA (320×240 pixels) OLED color display
  • With through coating measurement, the gauge can measure the net thickness of the substrate without removing the paintings.
  • Unique multiple-wave verify mode, all the thickness values have been checked through 3 to 9 times of echos, which makes the result more reliable and accurate.
  • Can store 100,000 thickness values and 1000 waveforms (PM-5DL Only)

Tips: What are the factors affecting the value of ultrasonic thickness gauge?

1. The surface roughness of the workpiece is too large, resulting in poor coupling effect between the probe and the contact surface, low reflection echo, and even unable to receive the echo signal.

2. When the radius of curvature of workpiece is too small, especially when measuring thickness of small diameter tube, the sound intensity transmittance is low because the surface of common probe is plane and the contact with surface is point contact or line contact.

3. The detection surface is not parallel to the bottom, and the acoustic wave scatters when it meets the bottom, so the probe of ultrasonic thickness gauge cannot accept the signal of the bottom wave.

4. Castings and austenitic steels have severe scattering attenuation when the ultrasonic wave pass through due to inhomogeneous structure or coarse grain. The scattered ultrasonic wave propagates along complex paths, which may obliterate the echo and cause no display.

5. There is some wear on the contact surface of the probe.

6. There are a lot of corrosion pits on the back of the measured object.

7. There is sediment in the measured workpiece (such as pipeline). When the acoustic impedance difference between the sediment and the workpiece is small, the ultrasonic thickness gauge shows that the thickness reading is increased by the thickness of the sediment.

8. When there are defects (such as inclusions, sandwiches, etc.) in the material, the display value is about 70% of the nominal thickness. At this time, the ultrasonic flaw detector can be used for further defect detection.

9. The temperature will affect the reading of ultrasonic thickness gauge. Sound velocity in general solid materials decreases with increasing temperature.

10. Cascade material and composite (heterogeneous) material. It is impossible to measure uncoupled laminated materials because ultrasound cannot penetrate uncoupled space and cannot propagate uniformly in composite (heterogeneous) materials.

11. The influence of coupling agent. Sound speed is selected incorrectly. Metal surface oxide or paint coating may also affect the thickness value of ultrasonic thickness gauge.
