The non-contact diameter measuring system, is mainly used in the measurement of the outer diameter of various wire rods, bars, wires and pipes. The.

The  takes the laser scanning method as an example. It adopts the probe imported from Japan, . The acquisition frequency reaches 2000 times/second. The probe uses a self-excited infrared light source, which overcomes the measurement problem in dim environments.

The detection principle is as follows

Figure 2: Working Principle

First, the mold oscillator generates self-excited high-frequency pulses, which are sent to the comparator and the stepping servo motor respectively. The stepping servo motor drives the octahedral prism to rotate at a high speed, and reflects the infrared laser emitted by the laser generator to the convex lens A. It becomes parallel light, and then collects on the photosensitive element C through the convex lens B in the infrared receiving probe. The photosensitive element C converts this signal into a corresponding electrical signal and sends it to the other end of the comparator to compare with the original signal.

When there is no object to be measured in the measuring probe, the pulse signal at both ends of the comparator will be the same. Therefore, there is no difference output: when there is an object to be measured in the measuring probe, the photosensitive element C will output no pulse signal during the period of scanning through the object to be measured. Therefore, there will be a difference input for a period of time at both ends of the comparator, which corresponds to the diameter of the measured object. By calculating the oscillation period of the pulse and the length of the time slice without pulse, the diameter of the measured object can be known.

The composition and functions of the system

The system consists of the following main parts (as shown in Figure 1)
