GDUD-PTM Ultrasonic Flaw Detector For Electrical Power Tower
● TFT true color screen.
● Using leading embedded digital system technology, the electrical performance indicators of the instruments are designed and manufactured according to the standard EN 12668.1 - 2000.
● Advanced and safe lithium polymer battery and power management technology, automatic alarm and protection. The automatic standby screen saver can be set to make the equipment more energy-efficient and longer-lasting, and to ensure continuous and efficient flaw detection.
● Application software that integrates intelligent and powerful processing functions, direct-reading user interface and operation mode, or digital knob one-button operation mode.
● Large-capacity detection parameters preset channel, convenient for users to operate on different detection objects. Powerful data storage and static analysis capability, coupled with real-time flaw detection date and time synchronization clock tracking and recording, make detection easier.
● With variable width square wave pulse generator, and variable voltage transmitter to get variable transmitting power. Multi-stage damping settings allow the probe to be optimally matched to the instrument.
● Good amplifier characteristics and frequency band characteristics. The amplifier has an accuracy of 0.1dB, with wide-band and narrow-band operation modes, and probe frequency can be measured real time, which provides better detection results when the user detects different materials.
● With wide detection range(up to 6 meters) and powerful signal resolution, min. 0.1mm continuous adjustable range. Choose a suitable range and the corresponding probe for good near-field resolution.
● Excellent high-speed hardware real-time processing and optimized design of pulse repetition frequency control function to meet the best effect for different crystal grains and detection distance. The echo display has dynamic effect and no hysteresis.
● Automatic calibrations for probe and curvature surface, which optimizes the coupling between the probe and test object and ensures accuracy.
● With distance-amplitude (DAC) curve function, program-controlled sound and light alarm control.
● With high-speed USB interface, easily communicate with the computer, support computer management processing functions and online programming.
● Light aluminum alloy hand held housing, which has excellent anti-interference performance. Meets IP65 protection class.
