What is the testing principle of the laser automatic thickness gauge and what are its characteristics?
The laser automatic thickness gauge is an online automatic thickness gauge specially developed for the plate production line. It has the characteristics of high measurement accuracy, fast measurement speed, multiple measurement points, timely reflection of thickness control information urgently needed for production, retention of production process data for investigation, and no radiation hazards. It can effectively improve the measurement and control environment, increase production efficiency, improve yield and product quality.
The automatic thickness gauge adopts the optical triangulation method to measure the thickness. It uses the light beam emitted by the laser source to irradiate the measured object to form a spot. The spot is imaged by the imaging lens to the photoelectric sensor (PSD, CCD, etc.). The signal is converted into an electrical signal, and the position of the image spot on the sensor can be determined according to the electrical signal, and the thickness of the measured object can be calculated from the geometric relationship.
What is the testing principle of the laser automatic thickness gauge and what are its characteristics?
The optical triangulation thickness gauge has high measurement accuracy, good measurement repeatability, wide application range, not limited by the material to be measured, and can be applied to most opaque objects. In addition, it has the advantages of small size, low cost, It is not affected by the external magnetic field and humid environment, and has broad application prospects.
The advantage of the laser thickness gauge is that it is a non-contact measurement without loss of accuracy due to wear, especially suitable for multi-point measurement in motion. Moreover, compared with the ultrasonic thickness gauge, the accuracy is higher, and there is no radiation pollution compared with the ray thickness gauge. The ranging sensor of Lanpeng Laser Thickness Gauge is installed on an adjustable bracket, which can realize wall thickness measurement at any position.
The raw data measured by the laser probe are transmitted to the control box for processing and calculation. The control cabinet is equipped with synchronous circuit, alarm control circuit, motor drive circuit and other circuit systems, which can realize data storage, display and other functions, and the measurement results are directly displayed on the computer screen. An alarm light is set on the slope of the control box. When the measured data exceeds the set standard value, the device sends out an alarm signal.
The automatic thickness gauge is a device capable of high-precision on-line detection. On-line detection is conducive to the timely control of the thickness and size of the plate to ensure the real-time detection. At the same time, the data that can be detected is sufficient to realize the overall detection.
