Page 3: Overview
1 Overview The UTG-2800 is a digital ultrasonic thickness gauge. Based on the same operating principles as SONAR, the instrument is capable of measuring the thickness of various materials with accuracy as high as 0.001”. It is suitable for testing a variety of metallic and non-metallic materials. -

7) Battery icon indicates the capacity of the battery. 8) Auto sleep and auto power off function to conserve battery life. 9) Optional thermal mini-printer (MP-2800) to print the measured data via USB port for UTG-2800. 1.3 Measuring Principle The digital ultrasonic thickness gauge determines the thickness of a part or structure by accurately measuring the time required for a short ultrasonic pulse generated by a transducer to travel through the thickness of the material, reflect from the back or inside surface, and be returned to the transducer. -

Page 7: Preparation
3 Preparation 3.1 Transducer Selection The gauge is capable of performing measurements on a wide range of materials, from various metals to glass and plastics. Different types of material, however, will require the use of different transducers. Choosing the correct transducer for a job is critical to being able to easily perform accurate and reliable measurement. The following paragraphs highlight the important properties of transducers, which should be considered when selecting a transducer for a specific job. - Page 8 Selection of the proper transducer is often a matter of tradeoffs between various characteristics. It may be necessary to experiment with a variety of transducers in order to find one that works well for a given job. The transducer is the “business end” of the instrument. It transmits and receives ultrasonic sound waves that the instrument uses to calculate the thickness of the material being measured.

Page 9: Condition And Preparation Of Surfaces
3.2 Condition and Preparation of Surfaces In any ultrasonic measurement scenario, the shape and roughness of the test surface are of paramount importance. Rough, uneven surfaces may limit the penetration of ultrasound through the material, and result in unstable, and therefore unreliable, measurements. The surface being measured should be clean, and free of any small particulate matter, rust, or scale. -
Page 10: Sound Velocity Calibration
At this point, the instrument has successfully calculated its internal error factor, and will compensate for this value in any subsequent measurements. When performing a “probe zero”, the instrument will always use the sound velocity value of the built-in probe-disc, even if some other velocity value has been entered for making actual measurements. - Page 11 4.3.2 Calibration to a known velocity Note: This procedure requires that the operator knows the sound velocity of the material to be measured. A table of common materials and their sound velocities can be found in Appendix A of this manual. 1) Press the key to activate the calibration mode.

4.3.4 Storing Sound Velocities in Memory The UTG-2800 is capable of storing multiple sound velocities to enable the user to quickly check different known materials. Example: If you are testing steel at .233 in/us, you can quickly change to one of your stored sound velocities when you need to test your aluminum, brass, plastic, etc. -
Page 13: Changing Resolution
4.6 Changing Resolution UTG-2800 has selectable display resolution, which is 0.01” / 0.001” (0.1mm and 0.01mm). Press down the key while turning on the gauge will switch the resolution between “High” and “Low”. -

. When the battery capacity runs out, the battery symbol will be shown as and will begin to flash. When this occurs, the batteries should be replaced. Pay close attention to polarity. Please remove batteries if the UTG-2800 will not be used for an extended period of time. 1.800.561.8187 information@itm.com www. -

4.15 Connecting to a Computer The UTG-2800 is equipped with a USB port. Using the accessory cable, the gauge has the ability to connect to a computer, or external storage device. Measurement data stored in the memory of the gauge can be transferred to the computer through the USB port. -
Page 16: Appendix B Applications Notes
Appendix B Applications Notes Measuring pipe and tubing. When measuring a piece of pipe to determine the thickness of the pipe wall, orientation of the transducers is important. If the diameter of the pipe is larger than approximately 4 inches, measurements should be made with the transducer oriented so that the gap in the wearface is perpendicular (at right angle) to the long axis of the pipe. - Page 17 Couplants All ultrasonic applications require some medium to couple the sound from the transducer to the test piece. Typically a high viscosity liquid is used as the medium. The sound used in ultrasonic thickness measurement does not travel through air efficiently. A wide variety of couplant materials may be used in ultrasonic gauging.
