  ULTRASONIC THICKNESS GAUGE — A1207 (A1207C) Change the ultrasound velocity in the device. Put the device on the sample block and compare the real thickness with the readings of the device. If it is necessary you will need to repeat these actions until the device shows the same thickness of the sample block as it’s real thickness is.

• Page 18: Principles Of Operation

  ULTRASONIC THICKNESS GAUGE — A1207 (A1207C) PRINCIPLES OF OPERATION A1207 and A1207C operate on the ultrasonic pulse-echo principle. The device measures the time of double travels of ultrasonic oscillations through the material from one surface to another. This time is recalculated to the meaning of thickness.

• Page 19: Some Notes On Operation

  Electro-acoustic screen (that is the line on the operating surface of the probe) in A1207 should be directed perpendicular to the tube’s axle. Pressing the probe to the tube’s surface and watching the readings of the device, you need to lean the probe from side to side in the plane perpendicular to the tube’s axle.

Some characteristics of constructive materials can essentially limit the exactness of measurement and range of measured thickness. 1. Sound dispersion In some materials (for example, some types of stainless steel, cast-iron, composites) the sound energy is dispersing (on crystallite moulding or on additions in composites).

  ULTRASONIC THICKNESS GAUGE — A1207 (A1207C) After that leave the velocity choice button. On the display you will see horizontal strokes. In 1-2 seconds they should blink, and that will mean that the device is ready for work. 7.3. REPLACEMENT OF THE PROBE’S CAPSULE When the probe’s capsule is worn out it is possible to replace it.

• Page 23
  After you have replaced the probe’s capsule you need to check the exactness of measurement on the testing samples. A1207 is tested on the testing samples with known ultrasound velocity in them with the thickness of 0,8 – 30 mm. The A1207C version is tested on the samples of 10 –…
