DMD-96Dual-frequency Four-channel Eddy Current flaw detector

Product Model:DMD-996

Instrument Introduction:

DMD-96Dual-frequency four-channel eddy current flaw detector features a wide testing frequency, ranging from64HzPlease provide the Chinese content to be translated.5MHzAll have quartz crystal stability, thus suitable for metal materials with varying conductivity.

This instrument utilizes eddy current impedance plane and time-base scanning display technology to simultaneously show the two-dimensional graph of the eddy current signal and its time-base curve of the detection object in multiple windows on the same screen. All operations are conducted through menu-driven human-machine interaction and keyboard control. Standard detection programs can be stored in large quantities on both software and hardware, allowing for easy access by users at any time. Significant detection results can be frozen on the screen with textual annotations and can also be saved on software and hardware or printed as hard copies.

DMD-96Dual-frequency four-channel eddy current flaw detector features strict decibel gain control0~90dBAdjustment quantity0.5 dB/Files to meet various testing standard requirements for different occasions.

DMD-96The dual-frequency four-channel eddy current flaw detector features four physical detection channels and is a general-purpose instrument for on-line, off-line, or pre-service, in-service detection of metal components in industries such as automotive, petrochemical, metallurgical, and mechanical. It does not require coupling medium or contact with the workpiece during the detection process, making it easy to achieve automation. Additionally, with multiple detection channels, it can meet the one-time flaw detection requirements of multiple production lines or multiple detection surfaces of a single workpiece, suitable for mechanical components such as welding steel strips, sucker rods, valve stems, pins, gears, hubs, needle roller bearings, hollow shafts, and screw blanks, as well as metal tubes, bars, wires, and shapes.
