1.0 INTRODUCTION

The Electromatic TI-CMX is an ultrasonic thickness gauge that measures with extreme versa-

tility. It has the ability to simultaneously measure coatings and material thicknesses while

maintaining the ability to locate pits, flaws and defects in the material. Based on the same

operating principles as SONAR, the TI-CMX is capable of measuring the thickness of various

materials with accuracy as high as ± 0.001 inches, or ± 0.01 millimeters. The principle advan-

tage of ultrasonic measurement over traditional methods is that ultrasonic measurements can

be performed with access to only one side of the material being measured.

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

rest solely with the user of the instrument. Other errors may occur from measuring

coated materials where the coating is insufficiently bonded to the material surface.

Irregular and inaccurate readings may result. Again, the user is responsible for proper

use and interpretation of the measurements acquired.
