1.2 Thickness Measurement System Description
This section explains how the measuring machine works. The task of the MTS 8202.LLT
measuring machine is non-contact thickness measurement of belt/strip material.
1 Triangulation scanner
2 Calibration object
3 Drive
Fig. 1 Schematic representation of the measuring machine
The measuring method of the unit is based on double-sided thickness measurement,
consisting of two laser-optical triangulation scanners, which measure the target from
opposite positions. The thickness of the target is calculated on the touchscreen IPC.

Fig. 2 Sensor arrangement for the thickness measurement
The thickness determination does not require any complex target support. The main
advantage is that vibrations of the target do not result in inaccurate measurement. The
positional tolerance of the target is determined from the working gap, the start of meas-
uring range (SMR)
, see Fig. 2 and the measuring range (MR) of the sensors (triangula-
tion scanners).
