1 Overview

The model TN-EE is a multi-mode 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 0.1/0.01 millimeters.
The multi-mode feature of the gauge allows the user to toggle between pulse-echo
mode and echo-echo mode (eliminating paint or coating thickness).

1.1 Product Specifications

There are two models available with the following measurement ranges:

-. TN 30-0.01EE

-. TN 60-0.01EE

1) Display：4.5 digits LCD with EL backlight.

2) Measurement Range: Pulse-Echo mode: (0.65～600)mm (in S teel), valid for both
models

Echo-Echo mode: (3～60) mm for TN 60-0.01EE.
Echo-Echo mode: (3～30) mm for TN 30-0.01EE

3) Sound Velocity Range: (1000~9999) m/s.

4) Resolution： 0.1mm/ 0. 01m m

Accuracy： ±（0.5%Thickness+0.01）mm, depending on materials and conditions

5) Memory for up to 20 files (up to 99 values for each file) of stored values.

6) Power Source: Two “AA” size, 1.5 Volt alkaline batteries. 100 hours typical oper­ating time (EL backlight off).

7) Communication：USB1.1.

8) Dimensions：150mm × 74mm × 32 mm.

9) Weight：245g

1.2 Main Functions

1) Multi-mode: Pulse-Echo mode and Echo-Echo mode.

2) Capable of performing measurements on a wide range of materials, including
metals, plastic, ceramics, composites, epoxies, glass and other ultrasonic wave
well-conductive materials.

3) Transducer models are available for special applications, including for coarse
grain material and high temperature applications.

4) Sensor Zero function, Soun d-Velocity-Cali br ati on function

5) Two-Point- calibration function

6) Single point mode and Scan mode. Seven measurements readings per second in
single point mode, and sixteen per second in Scan Mode.

7) Coupling status indicator showing the coupling status.

8) Units: Metric/Imperial unit selectable.

9) Battery information indicates the rest capacity of the battery.

10) Auto sleep and auto power off function to conserve battery life.

11) Optional software to process the memory data on the PC.

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. The measured two-way transit time
is divided by two to account for the down-and-back travel path, and then multiplied by
the velocity of sound in the material. The result is expressed in the well-known
relationship:

Where： H－Thickness of the test piece.
v－Sound Velocity in the material.
t－The measured roun d-trip transit time.

1. 2.1 Main Screen

Explanation:

1. Coupling Status: Indicates the coupling status. While the gauge is taking a

measurement, the coupling status should be on. If it is not on or not stable, the
gauge is having difficulties in achieving a stable measurement, and the thick­ness value displayed will most likely be erroneous.

2. Unit: Current unit system. “mm” or “in” for thickness value. “m/s” or “in/μs” for

sound velocity.

3. Battery Information: Displays the rest capacity of the battery.

4. Inform ation Display: Displays the measured thickness value, the sound

velocity and shows hints of current operation.
