Product Name: Ultrasonic Color Waveform Corrosion Thickness Gauge Model NO.: TG330 Trademark: pride Transport Package: Well Package Specification: 30*30*10 Origin: China Product Description Ultrasonic Color Waveform Corrosion Thickness GaugeLIVE COLOR WAVEFORM(A-SCAN).ConTROL OF GAIN, BLANKING, GATE, RANGE, DELAY, RF AND RECTIFY MODES.DYNAMIC WAVEFORM AND THICKNESS COLOR CHANGE ON ALARM.If the ordinary thickness gauges are incompetent in the rough applications. Please turn to our TG330, which will maximize measurement performance for challenging applications and provide you with the cost-effective measurement solutions.PRINCIPLESThe ordinary ultrasonic thickness gauge with the principle pulse/echo method could do the test by the following two conditions.1. The first underside echo must be higher than the gate. (The height of the electrical level of the gate is unadjustable)2. No other noise waves before the first underside echo are higher than the gate. (Otherwise, we will get the thickness where the noise wave are produced)For some conditions, the above situations could not be satisfied, for example, the highly corrosive near surface, coarse-grain materials (e.g. cast iron), aluminum, small diameter pipes, super thin sheet, super thick plate, rough surface, nonuniform inner structure, defect contained workpiece, lamination and so on which could not be tested by the ordinary gauges.TG330will solve the above problems easily.1. Make the first underside wave higher than the gate by adjusting the gain and height of the gate.2. Invalidate noise waves before the first underside wave by the function of blanking.Live Color A-ScanThe user could directly see the color waveform of the ultrasonic sound (or A-scan) on the screen, which is quite important for the occasions that we need to check the correctness of the testing results. Many cases will cause wrong testing results or even no readings. We could find the causes easily through the A-scan. Adjust the three parameters of GAIN, BLACKING, GATE, and then we will get the right readings. The uses for waveform: testing the correctness of thickness readings, finding out the causes of impacting the testing, and adjusting the parameters to solve the problems.GainAdjust the amplification factor of echo signal, increasing and reducing by 1 dB by hand. It is quite effective for acoustic attenuation materials (e.g. cast iron).BLANKINGInvalidate the waves within the red blanking strip, and omit the useless noise waves that impact the measuring like the waves caused by the rough surface or nonuniform inner structure.Specifications and AccessoriesOperating Principle:Ultrasonic pulse/echo method with dual-element probes.Measuring Range:0.5-508mm; 0.02-20 inchDepending on probe, material, surface condition and temperatureUnites and Resolution:mm- 0.01; 0.1inch- 0.001; 0.01Display ModesDigital Thickness ReadoutA-scan or WaveformMin./ Max.
