BKNFX Pre-Multi-Frequency Eddy Current Hardness Separator

Stimulating the coil makes a magnetic induction to the tested material. The induced electromotive force received by the testing coil is related to the shape and size of the material hysteresis loop. When the low-frequency sinusoidal wave excitation voltage is magnetically induced, the induced electromotive force obtained is also a sinusoidal waveform, usually including a fundamental wave. By measuring the fundamental wave component of the inductive potential of the testing coil, the measured alloy composition and heat treatment status can be obtained, thereby achieving material hardness sorting.

SHAPEMERGEFORMAT pre-multi-frequency eddy current sorter is an advanced eddy current sorter. It can identify and sort the bearing ring, roller, steel ball material composition, hardness, heat treatment state and mixing.

BKNFX Pre-Multi-Frequency Eddy Current Hardness Separator Characteristics

The mechanism of the self-specific differential eddy current detection technology is to obtain the proportional balance of an eddy current signal by using different parts of the same sample as the reference objects, thereby avoiding the chemical composition, metallographic state and surface shape of different parts. The influence of the different electrical conductivity and magnetic permeability of the metal material under the action of the external alternating electromagnetic field.

1. Non-destructive testing, no special requirements on the surface of the workpiece. (Avoiding the traditional detection method needs to destroy the state of the surface of the workpiece, and only need to prepare two standard samples in the same material and workpiece when debugging the instrument)

2. Fast, accurate and convenient. (The test only needs to put the workpiece into the probe, the efficiency is several times or even hundreds of times of the traditional detection method. For the qualified parts and the unqualified with the sound and light alarm function).

3. High sensitivity. (The gain and frequency used by different materials and heat-treated parts are continuously adjustable)

4. Simple operation. (The man-machine dialogue function is set inside the instrument)

5. The display is intuitive. Software written using the WINDOWS operating platform makes the instrument easier and smarter to use.

6.Suitable for large-scale inspection needs, to ensure product quality is foolproof. (It is possible to perform 100% inspection of the raw materials used and the finished bearings instead of the conventional sampling test)
