Introduction
This portable digital ultrasonic flaw detector is a color TFT LCD display, reflecting the most advanced technology, light and small size of the weight of the instrument, only 1.4Kg., Which featured not only a superior digital ultrasonic flaw detector, is a square wave generator, and also as an image of the detection equipment, and is equipped with a variety of interfaces, to meet user needs a variety of detection.
The instrument's color TFT LCD screen, even in direct sunlight glare environment, but also clearly show high-resolution B-scan, TOFD sweep and other image-based waveform; instrument uses the domestic industry-leading tunable square wave excitation technique for detection of high attenuation or a thick piece has good penetration and SNR; unique interface provides the user with the instrument as a separate square-wave generator uses; high-speed network interface provides remote data transmission and control function; high-speed USB host interface can not only high-capacity external storage devices such as USB mouse can also be connected to an input device to facilitate the efficient analysis of the image of the waveform; two-dimensional incremental encoder interface, the unique design allows either redundant instruments used in voltage or current-type encoder can be as to achieve the detection position, obtain excellent B ultrasonic waveform sweep or TOFD image.
Features
- The maximum sampling rate of up to 640MHz, the measurement resolution 0.1mm, minimum range 2mm.
- Operating frequency 0.5MHz ~ 20MHz, sensitivity margin of up to 62dB, low frequency there is a better signal to noise ratio.
- High brightness, high-resolution (800x480) color TFT LCD display, the best reading test results.
- High-performance pulse square wave generator with adjustable options, and the probe to achieve the best match (non-inductive coil probe can be achieved excellent incentive), high attenuation material either detect or thin work pieces can bring optimal performance.
- Small size, light weight, battery, can work for more than eight hours.
- With LAN network interface, remote instrument control and data transmission. When the instrument is as a square wave transmitter, it can provide control of the instrument parameters.
- Two-dimensional incremental encoder interface for accurate position detection imaging (B, TOFD sweep).
- Simultaneous analog RF waveform output, output impedance 50Ω, can be used as source data acquisition and probe tests.
- High-speed USB interface to an external U disk data storage and dump.
- Built-in charging function; battery and DC power supply automatically detects the display; charging, automatic switching power supply, charging temperature dual protection.
- A variety of software features, covering all aspects of testing; unique originality universal knob to adjust the way to make testing more easily worry; humanized menu design, Chinese and English language menus
- Automatic test probe frequency, automatically optimizing the width of the square wave, with the probe and optimal instrument.
- Images of the thickness of the alarm function, waveform storage function and a variety of continuous waveform measurement mode.
- Fixed index measuring instruments function and waveform envelope function to achieve the peak memory.
