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 -.
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.

Different types of material, however, will require the use of different transducers. Choosing the correct transducer for an application is much important to perform easily accurate and reliable measurements.
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. The transducer connects to the instrument via the attached cable, and two coaxial connectors. When using transducers, the orientation of the dual coaxial connectors is not critical: either plug may be fitted to either socket in the instrument.
perpendicular to the material surface. In this case, it will be difficult to exactly locate tiny irregularities in the material being measured, as the focus of the sound beam no longer lies directly beneath the transducer. 4 Operation 4.1 Power On/Off The instrument is turned on by pressing the key. When the gauge is turned on, it will first perform a brief display test by illuminating all of the segments in the display.
3) Use the key and the key to scroll to the probe model currently being used. Be sure to set the right probe model to the instrument. Otherwise, there will be errors or deviations. 4) Apply a single droplet of ultrasonic couplant to the face of the metal probe disc. 5) Press the transducer against the probe disc, making sure that the transducer sits flat against the surface. 6) Remove the transducer from the probe disc.
7) Press the key again. The M/S (or IN/μS) symbols should begin flashing. The gauge is now displaying the sound velocity value it has calculated based on the thickness value that was entered. 8) Press the key once again to exit the calibration mode and return to the measurement mode. The gauge is now ready to perform measurements. 4.4.2 Calibration to a known velocity Note: This procedure requires that the operator knows the sound velocity of the material to be measured.
4.5 Performing Measurements When the instrument is displaying thickness measurements, the display will hold the last value measured, until a new measurement is made. In order for the transducer to do its job, there must be no air gaps between the wearface and the surface of the material being measured. This is accomplished with the use of a “coupling” fluid, commonly called “couplant”.
When the scan mode is turned off, the single point mode will be automatically turned on. Turn on/off the scan mode by the following steps: Press the key to switch the scan mode on and off. It will display the current condition of the scan mode on the main screen. 4.7 Changing Resolution The gauge has selectable display resolution, which is 0.1mm and 0.01mm. Press down the key while turning on the gauge will switch the resolution between “High” and “Low”. 4.
3. Press the key to enter the selected file. It will display the current record number (for example, L012) and the record content. 4. Use the key and the key to select the desired record. 5. Press the key on the desired record. It will automatically delete this record, and display “-DEL”. 6. Press the key to exit the data logging functions and return to measurement mode. 4.10 EL Backlight With the background light, it is convenient to work in the dark condition.
6 Transport and Storage Keep it away from vibration, strong magnetic field, corrosive medium and dust. Storage in ordinary temperature.

these. In echo-echo mode, the paint/ coating thickness will be eliminated entirely and the steel will be the only material measured. Suitability of materials Ultrasonic thickness measurements rely on passing a sound wave through the material being measured. Not all materials are good at transmitting sound. Ultrasonic thickness measurement is practical in a wide variety of materials including metals, plastics, and glass.
