Overview of outer diameter measuring instrument

According to the basic contents of the outer diameter measurement, the outer diameter measurement is to measure the diameter of cylindrical objects, including cables, rubber plastics, round steel high-speed wires, etc. Generally speaking, the on-line detection device is selected for the measurement in the production line, which can carry out real-time detection and detect all parts of the whole rolled material.

High precision detection of laser outer diameter measuring instrument

The measuring accuracy of the outer diameter measuring instrument is very important. The term "accuracy" is actually an abbreviation. It compares the measurement result with the measured true value and expresses it according to the degree of contrast and accuracy. It can also be understood as the degree of deviation of the measurement result from the measured outer diameter value. Therefore, this method actually combines the accuracy and accuracy of the measurement, so it is also called "accuracy". In many manufacturers, there are rigid requirements for the measurement accuracy. Therefore, in the production of the outer diameter measuring instrument, it is necessary to ensure that its accuracy meets the production requirements. At present, its measurement accuracy generally reaches 0.01mm and 0.02mm, and the measurement accuracy of the thin wire can reach ± 0.003mm.

High frequency detection of laser outer diameter measuring instrument

Since the laser outer diameter measuring instrument is used in the production line as an on-line detector, its measuring frequency naturally needs to be high in order to meet the high-speed production demand. At present, the laser outer diameter measuring instrument has two kinds of frequencies, one is 500Hz and the other is 2000Hz. The higher the measuring frequency is, the smaller the interval distance between the given detection data is. Of course, it also has a certain relationship with the production speed. In short, High frequency detection enables the outer diameter detection to obtain more comprehensive detection data.
