IMPORTANT NOTE:

Inherent in ultrasonic thickness measurement is the possibility that the

instrument will use the second rather than the first echo from the back

surface of the material being measured. This may result in a thickness

reading that is TWICE what it should be. Responsibility for proper use of

the instrument and recognition of this phenomenon rests solely with the

user of the instrument.

1.0 INTRODUCTION NOTES The TI-25P is a precision Ultrasonic Micrometer. Based on the same operating principles as SONAR, the TI-25P is capable of measuring the thickness of various materials with accuracy as high as ± 0.001 inches, or ± 0.01 millimeters. The principle advantage of ultrasonic measurement over traditional methods is that ultrasonic measurements can be performed with access to only one side of the material being measured.

M Symbol: When the M symbol is on, in conjunction with the /s symbol, the TI-25P is displaying a sound-velocity value in meters-per-second. + INMM/µs 1.8.8.8.8 3.3 The Transducer An additional important consideration when measuring laminates is that any included air gaps or pockets will cause an early reflection of the ultrasound beam. This effect will be noticed as a sudden decrease in thickness in an otherwise regular surface.

10.0 APPENDIX A: APPLICATION 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 Perpendicular Parallel of the pipe is larger than approximately four 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.

5.0 ZEROING THE PROBE 9.0 SPECIFICATIONS Setting the Zero Point of the TI-25P is important for the same reason that setting the zero on a mechanical micrometer is important. If the gauge is not "zeroed" correctly, all of the measurements the gauge makes will be in error by some fixed number. When the TI-25P is "zeroed", this fixed error value is measured and automatically corrected for in all subsequent measurements. The TI-25P may be "zeroed" by performing the following procedure: 1.

8.0 TAKING MEASUREMENTS 6.0 CALIBRATION PROCEDURE In order for the transducer to do its job, there must be no air gaps between the wear-face and the surface of the material being measured. This is accomplished with the use of a “coupling” fluid, commonly called "couplant." This fluid serves to “couple.” or transmit, the ultrasonic sound waves from the transducer, into the material, and back again.

Temperature of the Material 7.0 TRANSDUCER SELECTION The TI-25P is inherently 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 measurements.
