| Message: | LDC-X200 Laser Diameter Measurement System
Overview
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 system can detect the change of the diameter (outer diameter) of the measured object in real time under the high temperature state.
The working principle
The diameter measuring system takes the laser scanning method as an example. It adopts the probe imported from Japan, which can achieve an accuracy of plus or minus 2 microns in the range of 0.3 to 30 mm. The acquisition frequency reaches 2000 times/second. The probe uses a self-excited infrared light source, which overcomes the measurement problem in dim environments.
It adopts the measurement method of pulse parallel light scanning, and has a strong ability to resist the jitter of the measured object. (As shown in Figure 1) Since the shaking frequency of the measured object is much smaller than the scanning frequency, when the measured object A moves in the shakeable area, the measurement result will be able to ensure its accuracy because the time it blocks the beam does not change.
The composition and functions of the system
The system consists of the following main parts
1. A measurement frame with four pairs of high-frequency laser scanning probes and non-contact infrared thermometers is installed
2. Four intelligent signal processors connected with four pairs of high frequency laser scanning probes
3. Cold air blowing system for cooling and cleaning the measuring frame
4. High-performance intelligent controller responsible for front-end data signal processing and network communication
5. Data processing and analysis system installed with industrial grade PC, monitor and printer |
