The laser online thickness gauge has two detection methods, which are double-sided laser detection (2 laser triangulation sensors) and single-sided roll inspection (one laser triangulation sensor). Measure the distance from the surface of the material. According to the design arrangement, an additional sensor, usually a high-precision turbine sensor, is used to measure the distance between the double-sided sensors or the distance from the single-sided sensor to the reference roller.
The thickness of the product is the difference between the measured values. The data is processed and calculated by the built-in microprocessor of the SimVision DML sensor, and the data of the upper and lower laser sensors and the data of the turbine sensor are collected at the same time, and a large number of temperature compensation sensors are used to compensate the deformation of the sensor housing, thereby real-time processing of the thickness measurement .
The schematic diagram of the detection principle of the laser online thickness gauge is shown in the figure below.
