STG was developed for thick rigid panels upto 40 mm. Two laser distance sensors scan the distance to the surface above and below a plate that runs through an O-frame. This directly determines the thickness of the plate.
STG is a non–nuclear technology that does not require licensing or protection guards.
Thick Extruded Plastic Sheets and Plates
STG thickness gauges are available in widths of up to 4 m
Ultra-precise thickness measuring with an accuracy of ≤ 20 µm
STG is suitable for material thickness of up to 40 mm
Laser distance sensors work on the principle of optical triangulation. They traverse above and below the extruded sheet and measure the distance to the sheet surface.
These sensors are guided by linear guides and driven by a stepper motor.
A calibration curve, which is measured against a calibration tape without an extruded plate, serves as the basis for the measurement. This compares the value measured by the laser distance sensors and outputs it as a thickness value.
