NBOND－17 Model

Computer eddy current detector

Instruction:

NBOND-17 Eddy Current Flaw Detector is a multi-functional, practical, high Cost-effective apparatus. it has many years of manufacturing experience in eddy current detector, meeting the needs of all types of users. it can be widely used in various types of non-ferrous metal, ferrous metal pipes, rods, wire, wire, profiles online and offline testing. It has a high defect detection sensitivity in metal tubes, rods, wire, wire, profiles of the defects such as surface cracks, dark crack, crack open the folder. It provides windows in Chinese user interface, Modular way of operating, a variety of display modes for choosing and applying all-digital design techniques. We needn’t readjust the equipment when changing product specification, realized a fool-type operation.

1,Bearing outer ring, Bearing inner ring, Gear Blanks, Ring-shaped metal parts , Auto Parts

2,Brass, steel, stainless steel pipe, welded pipe, aluminum tube, steel wire, double pipe, copper Clad Aluminium, Copper Clad Steel, Metals such as Wire Rod Production Line on-line and off-line nondestructive testing

3,Nondestructive testing such as Oil casing, sucker rods, hollow shaft

4,Detection such as Condenser tubes, air conditioner pipe, auto Tubing

5 ,Be suitable for all kinds of Metal wire rod and bar tube nondestructive testing

一．Detection Principle ：

Detector coil will be passed through the instrument at a certain frequency of alternating current, when the checked specimen is near the coil, the geometry of the specimens, electrical conductivity and magnetic permeability and specimen of metallurgy and mechanical defects will cause the detector coil impedance change. The changed signals of coil impedance by detected instrument are amplified and converted driver alarm or display device, and finally the defective samples will be detected out

二、Technical Parameters

6, Real-time impedance flat panel display

7, The provision of X-t, Y-t, V-t three time base scan for the choice of real-time display mode

8, Automatically record and display the location of defects

9, Marking the dynamic fixed-length feature(no need for the high-speed testing)

10, Function of the head and tail signal resection

11, High-precision real-time and delay alarm output

12, Number of phase and amplitude alarm technology

13, Date and time display Automatically

14, Eddy current testing signal playback, analyze, save and print functions

15, Windows user interface, modular man-machine dialogue

16, Power Supply:180V~240V 50HZ

17, The temperature of environment:-20°C~+40°C

Circuit working Principle:

The frequency produced by oscillator is 100 hz ~ 1 MHZ, two-way adjustable sine wave. The frequency will be transfer ed all the way to wide frequency power amplifier as the excitation source probe, probe measuring ac bridge composed of bridge arm. When the probe test sample, sample physical properties change excitation source induced eddy current field change on sample, to probe the original impedance (solid components R and virtual X) change, which destroy the balance of the original communication bridge, get containing test signal voltage U, the signal after broadband preamplifier, into the X, Y resolver decomposition.
