Usually, the measuring tool used to scientifically test the diameter of the wire rope is the caliper, and the diameter of the stainless steel wire rope can be scientifically measured using the caliper. When it is used, the claw distance of the caliper needs to be enough to span two adjacent rope strands to achieve the purpose of smooth measurement. At the time of measurement, it is also necessary to know that the actual measurement needs to be carried out on a straight line with no load wire rope.

The diameter of the wire rope needs to be tested in the absence of tension and needs to be tested at two points at a suitable distance from the end of the rope at least 1 meter apart from each other. At the same time, you need to be able to measure two diameters vertically in different directions, and then use the data of four measurements to calculate the average diameter value. As for the numerical calculation of the ellipticity of stainless steel wire rope, it is necessary to subtract any two values of these four measurements. Of course, this is a traditional inspection method, although the operation may be relatively complex, but the accuracy is high, and the cost of testing equipment is relatively low.

In addition, the current measuring instrument for inspecting the diameter of the wire rope also has a diameter measuring instrument, which can directly measure the diameter of the wire rope without contacting the measured object. The device is the use of the principle of laser beam, detection range between 1-80mm. If the halogen beam detector is used, the test range can be between 0-25mm, and you can choose the instrument according to the test range.
