PXUT-390 digital ultrasonic flaw detector
PXUT-390 digital ultrasonic flaw detector, using a new type of super large screen high brightness TFT display,instrument and sleek, compact,
The screen is large, bright light without shading can clearly display instrument, powerful function, stable performance, simple operation, is a notebook a superior performance over
Ultrasonic flaw detector.
Function and characteristics:
● calendar clock, the instrument automatically records the date and time, free testing instrument and probe performance (including surface probe), instrument calibration automatically, can measure the thickness of the material and the material velocity.
● 10 independent detection channels (extensible), a variety of inspection technology and standards are generated automatically, can be free to set the industrystandard of testing technology, on-site inspection without carrying test block.
The high sensitivity, the gain of 120dB, echo suppressioncan be adjusted freely, does not affect the instrumentgain and linear.
Gain the unique automatic regulation and peaksearching, so that testing is fast and accurate.
● with full wave, half wave, negative half wave, radio four ways to help the defect location and qualitative.
● DAC, AVG curve generation and sectioned, limitedsampling points can be carried out without, compensation and correction. DAC curve automatic floating with the gain, automatic expansion process can be specified with the sound, echo distance amplitude compensation.
● the defect echo parameters (distance, horizontal,vertical, amplitude, dB equivalent, aperture value) real-time display.
● with peak memory function, echo envelope, freeze,surface modification, door inner broadening etc..
● can automatically altimetric defect crack use endpointdiffraction wave.
● into the wave and wave alarm, door, door, door widehigh continuously adjustable.
● with B- scanning function, can display the workpiece defect shape. Complete and weld workpiece profile display, so that testing has more authority.
The strong data processing ability, can be retrieved and processed according to the date, the number and serial number, can realize data communication and datamanagement and computer, can directly print inspection report.
● external SD card, real-time continuous recordingdynamic waveform, and can be connected with theprojector, used for teaching demonstration, etc..
