Description

KW-4 Performance Characteristics

  1. It is in the way of man-machine dialogue and menu operation, and with three operation modes of touch screen, button, jog dial, which is simple and easy to use.
  2. It has the input method of built-in intelligent English and full touch information, but also USB external keyboard or mouse, which is concise and practical.
  3. The eight inspection channels are directly switched by the electronic switch and touch screen, also can be automatically transferred to the corresponding inspection process file.
  4. After the completion of a device debugging, you can backup parameters to the computer or U disk, also copy to another device.
  5. It supports download upgrades firmware online. The users do not need to return the instrument to the factory but upgrade through the U disk firmware.
  6. The operator need only a few minutes to complete the calibration and setting of velocity, incident zero, refraction angle, probe cutting-edge and other parameters. It is built with shaft type inspection process in the instrument; the daily performance check is simple and fast.
  7. Preview and print all kinds of reports in the ‘Railway truck axle assembly, maintenance and management rules’ and ‘Railway passenger car axle assembly, maintenance and managementRules’.
  8. It uses average, correlation and other computer signal processing technology to reduce random noise and external electromagnetic interference to improve the signal to noise ratio.
  9. It has built-in 16GB storage space (about one hundred thousand flaw detection files) and support USB, network expansion.
  10. It uses the high brightness TFT color touch display and has the features of fast response, real-time, clear and stable to display waveform or position the value. The brightness can be adjusted and has a good visibility whether using inside or outside.
  11. It can transfer and save the data with external U disk and also communicate with the computer through LAN interface to carry out the mutual transmission of waveform, chart and file to realize the computer management of the of flaw detection result.
  12. It has the bus axle, bus rims, freight car axle detection, and one machine with three systems and without interference.
