thicknessCONTROL MTS 8202.LLT / 4350127.347
1.2 System description
This section explains how the measuring system works. The task of measuring system
MTS 8202.LLT is non-contact thickness measurement of belt/strip material.

4 Drive
Fig. 1 Schematic representation of the measuring system
The measuring method of the measuring system is based on double-sided distance
measurement, consisting of two laser-optical triangulation scanners, which measure the
target from opposite positions. The thickness of the target is calculated in the IPC touch-
screen.

Fig. 2 Sensor arrangement for the thickness measurement
The thickness is measured without involved placement of the measured object. 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).
