YUSHINDT YUT2820 ultrasonic flaw detection (UFD) instrument AVG Linear dispersion

YUT2820 ultrasonic flaw Detector is a portable industrial non-destructive testing instrument, which can quickly, conveniently, damagelessly and accurately detect, locate, evaluate and diagnose a variety of defects (cracks, porosity, porosity, inclusions, etc.) inside the workpiece. It can be used both in the laboratory and in the engineering field.

Scope of application

It is suitable for all kinds of metal materials, all kinds of welded parts, forgings, castings, etc., and is widely used in the design stage, manufacturing process, finished product inspection, in-service inspection and other fields in boilers and pressure vessels, aerospace, electric power, petroleum, chemical industry, offshore oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing industry, steel structure, railway transportation, nuclear power, universities, road construction, dam construction, bridge construction and other fields.

Features

The square wave pulse generator with variable amplitude and width was launched in CHINA, which replaces the traditional method of changing the damping matching probe, and obtains a good probe matching by adjusting the pulse Voltage and width, thereby improving the near-surface resolution or penetration. It is particularly suitable for difficult-to-penetrate applications that require high penetration and low noise, such as inspecting large forgings, castings or non-metals.

• The Voltage of the pulser is continuously adjustable from 50 to 400 volts, providing excellent probe output for both thin plates and difficult-to-penetrate workpieces

• The pulse width is continuously adjustable from 25 to 1000 nanoseconds, matching probes of different frequencies for very good sensitivity

• Innovative high-energy lithium battery for computer notebooks

The full-screen display function allows the echo display area to cover the entire screen, giving workers a significant window experience

Solid waveform display, increase the visual contrast of the waveform, and it is not easy to miss the detection for fast scanning

Large-capacity memory for up to 1000 datasets, including waveforms, curves, parameters, etc. (including 1000 channels in the traditional sense)

Impedance matching is adjustable in four positions (33/50/100/500 ohms) for optimal probe performance and to meet different requirements for sensitivity and resolution

The echo signal filter is adjustable in two positions (1-4MHz, 0.5-15MHz), highlighting the advantages of narrow and wideband filters, respectively

The repetition rate can be adjusted in multiple levels to avoid reverberation (phantom) signals when detecting large workpieces

There are two operation interfaces in Chinese and English

The operation is simple, and the user can quickly grasp the use of the instrument

Basic functions

Peak memory: The real-time envelope displays the highest wave of the defect, records the maximum value of the defect, helps to accurately locate the defect and quickly scan, and can also characterize the defect with the help of the envelope waveform

Auto Gain: Automatically adjusts the gain to the set amplitude height

Alarm function: incoming/losing alarm

Real-Time Clock: Automatically records the date and time of the stored waveform

Display Freezing: Capture waveform and sound path data at any time, and move the gate to measure echo parameters after freezing

Defect location: real-time display of sound path S, level X, depth Y, wave height H

Digital rejection: 0-80%, in 1% increments, without affecting linearity and gain

Data communication: communicate with the computer through the USB interface, transmit waveforms and data, and realize the management of flaw detection results and the generation and printout of flaw detection reports on the computer

Distance compensation of DAC curve: The instrument is designed with a distance compensation function, which only compensates the sensitivity of the signal at a long distance without affecting the near-field resolution, thus greatly improving the scanning range of the instrument:

φ value calculation: The defect echo height is automatically converted to the defect equivalent size

Distance compensation: According to the time-varying gain method, the flaw detection echo is compensated in real time to avoid missing small defects

Data communication: communicate with the computer through RS232 interface, transmit waveforms and data, and realize the management of flaw detection results and the generation and printout of flaw detection reports on the computer

2 independent measuring gates to monitor echo amplitude and sound path distance

During shear wave flaw detection, the depth of the second and third wave defects is automatically calculated according to the plate thickness

Complete DAC/AVG curve function, the curve changes with the change of gain, sound path, and displacement

Adjustable brightness of the true color TFT LCD screen, with a variety of color schemes to choose freely
