Product Features

1. The range of detectable steel wire ropes is large: it can detect steel wire ropes with diameters ranging from 6 to 150mm, including various structures such as round strands, triangular strands, flat strands, and irregular strands.

2. The main body of the Intros wire rope detector weighs less than 700 grams, making it the most lightweight among its peers; It is the preferred portable steel wire rope detector.

3. The Intros wire rope detector has good repeatability and high consistency in multiple tests: through comparative testing, the deterioration speed and law of the wire rope can be grasped.

4. High detection accuracy: using strong magnetic detection. The loss of metal cross-sectional area and the sensitivity of wire breakage signals can be collected.

5. Easy to operate: The output waveform diagram is simple, intuitive, easy to learn, and easy to understand. The waveform diagram can also be filtered and compared, and the results are clear at a glance.

6. Replace the corresponding lining of steel wire ropes with different diameters; After the inner lining wears out, there is no need to replace the entire magnetic head, only an inexpensive inner lining needs to be replaced

7. The intros detection instrument has dual LCD displays, and the results are very intuitive; Sound and light alarm, intuitive display of results.

8This instrument has powerful software processing capabilities to filter, cut, etc. noise; optional8-channel display, automatic report generation;

9. Powerful database support: INTRON has been engaged in steel wire rope testing for many years, has rich on-site experience, collected a large amount of testing data, and established a steel wire rope testing database.

10. It can effectively predict the remaining service life of steel wire rope.

The significance of using a steel wire rope detector

1. Replacing visual inspection, it is efficient, fast, and provides objective and intuitive basis for the detection of steel wire ropes.

2. Can measure the wear of the metal cross-section of the wire rope.

3. Not only can it detect external wire breakage in steel wire ropes, but it can also detect internal wire breakage in steel wire ropes.

4. By comparing multiple ropes under the same working condition and comparing the same rope multiple times, we can intuitively grasp the deterioration speed and law of the steel wire rope.

5. Accurately evaluate the remaining life of the steel wire rope and achieve scientific use of the rope.

6. Reliable prevention of wire rope breakage accidents to ensure safe production.

Detection Principle

As shown in the figure,The Intros wire rope detector adopts the principles of permanent magnet and leakage magnet. When testing, first use a set of permanent magnets to saturate the steel wire rope. Then, the magnetic head wraps around the steel wire rope and runs at a relatively constant speed. Any defects in the steel wire rope, such as breakage, wear, rust, etc., can cause changes in magnetic leakage and flux, which are then captured by Hall sensors and converted into electrical signals, outputting intuitive analog signals

Detection parameters

according to the standardsAS Ding M E15TI-01 "Electromagnetic Testing Method for Ferromagnetic Steel Wire Rope" stipulates that steel wire rope testing mainly tests two parameters:

LMA (Metal Cross Sectional Area Loss): focuses on examining the degree of metal area loss in the steel wire rope. By comparing the detection position with the reference position (i.e. the position with the largest metal cross-sectional area in the steel wire rope), a relative measurement value is obtained in%. The larger the value, the more severe the metal defect.

LF (local damage): focuses on examining discontinuities in the steel wire rope, such as broken wires, severe corrosion pits, etc. At the location of the damage, a leakage magnetic field is formed, and a voltage signal is output in mv. The value of this signal is related to the length of the fracture and the degree of damage.

LMA and LF images

Left image: The rope is inWithin the range of 20m~80m, the loss value of LMA metal cross-sectional area reaches 12%.

Right picture: The rope is shown in the diagramAt the position of 83.4m, a peak signal appears in the waveform of LMA metal cross-sectional area, and the loss of metal cross-sectional area reaches 0.6%. At the same location, in the LF local damage diagram, the appearance of peak and valley signals indicates that the steel wire at that position is discontinuous, causing a leakage magnetic field. After analysis, there is one broken wire at this location.
