Advantages of a contact laser thickness gauge include
Thickness is an important indicator of plate products need to test, how to accurately measure the thickness of the value, is also concerned about the problem, this article is mainly about the contact laser thickness gauge, of course, non-contact laser thickness gauge is also produced.
Laser thickness gauge:
Contact laser thickness gauge is to use the upper and lower two probes to directly measure the thickness of the strip, and the measured chemical composition of the strip as well as the material are hook degree has nothing to do. So the measurement accuracy is very high, and contact laser thickness gauge both dynamic measurement and lens detection.
Contact laser thickness gauge by the measurement unit is mainly composed of C-shaped frame, the upper pressure wheel, the upper sensor, the upper support arm, the lower pressure wheel, the lower pressure wheel support rod and other parts. Upper and lower pressure wheel and strip surface contact force controlled by air pressure, air pressure value should be based on the rolled strip material hardness and softness to determine the air pressure is too high on the strip there will be marks, air pressure is too low on the lower pressure wheel can not be completely in contact with the strip and affect the detection accuracy.
Laser thickness gauge of the upper and lower two contact sensors installed in the C-shaped frame of the upper and lower beam front. In order to prevent the upper and lower position of the strip floating affect the measurement, the installation distance of the two sensors is set to 60mm (such as the site can be reduced to a larger float this size). The lower part of the sensor is mounted on a pulley for real-time online thickness measurement. The control box is installed at the back end of the C-shaped frame, the control box is set to display data on the LCD screen. The raw data measured by the sensor is transmitted to the control box for processing and calculation, and the calculation results are displayed directly on the LCD screen.
The use of laser thickness gauge increases the rolling quality of the strip, improve the yield rate, become an indispensable detection tool for thickness control, especially with the combined use of automatic control system of the finishing mill, give full play to the effective measurement of the thickness of the strip during the rolling process, corrective action, play a huge role in the physical measurement of the strip.
