1. Introduction The UTG‐2650 is a simple to use, highly accurate, hand‐held Ultrasonic Thickness Gauge with the ability to measure ultra‐thin materials in super high resolution. Utilizing it’s state of the art microprocessor and ultrasonic technology the 2650 offers you many outstanding features such as quick scan and extended memory. It features reliable and stable readings, standard or dual element measuring modes, convenient data display (in both millimeters and inches),high resolution .0001” (0.
3. Names and Functions for UTG-2650 ● Power on/Reset key ON/RST –to turn on or reset the tester. When the tester is turned on, LCD will display the value of sound velocity used for the last measurement. The gauge will shut off automatically if idle for 4 minutes. ● Menu key MENU- to setup the tester .Press this key to move highlighted item to the following menus-Save(N=1,2,3,4 or 5),Menu, EE, OFF. ● Enter key to accept the job selected by . If Off is highlighted by pressing MENU the gauge .
4.Operation 4.1Calibration Set the sound velocity to be 0.232”(5900m/s) .Put a pea sized drop of couplant gel on calibration block built-in on the gauge. Press the probe on the face of the block to obtain measurement .LCD screen will display a value. Lift the probe off the block. Then press the up and down arrows to adjust the value on the display to match 0.157”(4.00mm). You may need to press the Back Arrow button to move the cursor from column to column. Once the value of 0.
4.6 Minimum Capture (Scan Feature) If this function is set to “ON” from system setting, it is ready to capture minimum reading in the measurement. LCD will show the current thickness while the probe is coupled with the sample .as soon as you release the probe from your part, the LCD displays the minimum reading and “MIN” will flash six times. Measuring during the flashing will send the results into the capture array to get the minimum reading. 4.
5.1.2Method of Precision Measurement This method involves increasing the number of measurement spots around a certain measurement point and expressing the thickness fluctuation in terms of isothickness contour lines, fig.3. Fig. 3 Fig 3. 5.1.3Method of continuous measurements Fig.4 As in fig.4, this method involves taking continuous measurements along a specified line according to the single measurement method, at intervals of 5mm or less.
Fig.6 Pipe sample Fig.7 Bottom view of probe 6.Maintenance Be sure to clean the probe and cable after each use. Grease, oil and dust will cause the cable of the probe to dry out and shorten life expectancy. If the unit is not to be used for a long period of time, remove the batteries to avoid battery leakage and corrosion of the battery contacts. Avoid storing the unit in a damp or extremely hot environment. ● DO NOT OPEN INSTRUMENT! This will automatically void your warranty.
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. Materials that are difficult include some cast materials, concrete, wood, fiberglass, and some rubber.
