LD7015
1 PRODUCT DESCRIPTION
Ultrasonic thickness gauge specifically designed to measure the thickness of
metallic and non-metallic materials e.g. aluminium, titanium, plastics, ceramics,
glass and plastics. It can also be used to monitor all types of pipes and pressure
vessels for loss of thickness due to corrosion or erosion. The gauge is easy to use
and will give accurate readings to an accuracy of 1%. This unit is not suitable for
cast iron due to its big crystalloid composition.

- Page 9 5.2 Sound velocity measurement To get a read out of sound velocity of the material with a known thickness: Obtain the thickness of the material by using a micrometer or calliper, then put the probe on the material until a value appears on the display. Remove the probe and press to adjust the value to match the same thickness as measured with the micrometer/calliper.

- Page 11 With different materials and situations, only one sample block may not be enough to get the most exact calibration. The more similar sample blocks, the more exact readings will be obtained. Ideally reference blocks are a group of different thicknesses of the same material. When calibration the gauge with different blocks, the variation of sound velocity will be minimised.
- Page 12 5. Multilayer-composite material It is impossible to read out the thickness of uncoupled multilayer’s as the ultrasonic wave cannot go through into the uncoupled space. Furthermore, the sonic wave cannot go through in to the composite material at an even speed. So ultrasonic reflect principles cannot be applied for measuring multilayer’s and composite material.
