Ultrasonic Flaw Detector MFD500B With High-resolution Multi-color TFT LCD Detecting Flaw In The Workpiece
1.Product Overview
Based on ultrasonic principle, digital ultrasonic flaw detector MFD500B with 320*240 TFT LCD, it can test, orient, evaluate and diagnose various flaws such as crack, lard, air hole in workpiece’s interior swiftly and accurately without any destruction. It can be used in Laboratory as well as in engineering filed. With range of 0-9999mm, it can meet the requirement for general defect inspection in manufacturing industry, metallurgical industry, metal processing industry, chemical industry and so on. Low power design with large capacity and high performance lithium battery module, it can be long standby for months. High quality with low price, it is the first choice for the practical economic model for ultrasonic testing equipment.
2.Function & application
The instrument can be widely used in locating and sizing hidden cracks, voids, disbands and similar discontinuities in welds, forgings, billets, axles, shafts, tanks, pressure vessels, turbines and structural components.
3.Instrument Features
Gate Alarm
Gate position, gate width and gate height can be adjustable at will. The B gate can chose to set wave-getting alarm or wave-losing alarm. The beep in gate and LED light can be alarmed or closed (the LED light alarm is very effective under the noise environment).
Data Storage
The instrument is built with mass storage, the data and files will not be lost because of instrument power breakdown. The storage contents included channel parameters, waveform pictures and video files. It supports 100 groups of flaw detecting parameters channels. It can preset well for the combination parameters of various types of probes and instruments as well as set testing standards for each industry freely. It can save 10000 pictures of detecting echo signals and parameters. It can realize to save, read and transfer the data via the USB port.
Video Function
The instrument supports for saving the inspection process as video file and save it to the internal storage card. Video file can be replayed through the instrument. The instrument can support 2 minutes video.
REAL-TIME CLOCK
Record and save the tracking record of detecting date and time in real time.
Communication
With USB2.0 high speed communication interface, it also can use special software to upload and download data through the USB port.
Battery Module
The large capacity lithium battery module is easy to be assembled and disassembled. It can be charged independently but also charged by inserting wire. Its continuously working time is more than 10 hours.
4.Working Principle
When presence of a defect in a workpiece with homogenous material, due to the defects, it will inform the interface among different mediums between the defect and workpiece. As the acoustic resistance is different at the interface, after the pulsing ultrasonic wave met the interface, it will produce reflection. The reflected energy will be received by the probe. Then it will show a reflection waveform in a certain abscissa position in the display screen which is the defect depth in the workpiece. The height and shape of reflecting wave would be different caused by the different defects which reflect the defect’s character.
Working Conditions
Operating Temperature: -10℃ to 50℃;
Storage Temperature：-30℃ to 50℃
Relative Humidity: (20 ~ 95)% RH
The surrounding environment should avoid of vibrating, strong magentic field, corrosive medium and heavy dust.
5:Operating Method and Attentions
Simple Operation Way:
1. Connect the probe to instrument with probe cable
2. Power on the instrument
3. Choose the channel and clear the present channel
4. Calibration the probe
Straight Probe: P-Delay
Angle Probe: P-Delay, X-value, Angle
5. Make AVG curve (straight probe), DAC curve (angle probe)
6. Choose the function setting
7. Detecting flaw in the workpiece
8. Record the flaws
9. Power off the instrument after operation
6:Notes
1. During pressing key operation, please not be too hard. Please not use the hands with much oil or mud for operating the instrument keypad to avoid affecting the keypad working life.
2. Please clear the instrument cover after operation
3. Please keep the instrument in a dry and clean place
4. Please avoid oil, water or other liquids into the instrument and clean the instrument surface regularly.
5. Make sure not twist or press the probe cable, communication cable and power cable. Please grasp the plug root during inserting or pulling the cable. Don’t grasp the cable for pulling or inserting.
6. Please make sure the standard battery for working power adapter for charging. Otherwise, the instrument would be damaged easily.
