Laser System for Inline Sheet Materials Thickness Measurement

RIFTEK:Our new system is designed for thickness control of various sheet materials (metals, plastics, wood).

We implemented a classic measurement scheme based on two triangulation sensors, placed on C-frame on opposite sides of the controlled sheet. The C-frame itself is installed on a linear translation stage with the ability to move across the sheet. A significant advantage of this type of system is low sensitivity to temperature fluctuations due to auto-calibration using a template of known thickness installed in the extreme position of the sensors.

The characteristic features of our system are:

• use of RF603HS high-speed laser sensors, which makes it possible to achieve high accuracy by averaging a large volume of measurements. In addition, the sensors are strictly synchronized and this eliminates the influence of sheet vibrations on the measurement accuracy;
• highly stable and durable C-frame made of reinforced carbon fiber.

The system also includes a control cabinet based on a panel industrial computer and the appropriate software with a lot of different functions.
