Double layer measurement
Reliable detection of double layers in sheet metal processing industry. The problems caused by an uneven feeding
of sheets and a strongly fluctuating distance to the sensor can be solved with the aid of parallel differential
measurement (illustr. 23 / illustr. 24) or differential thickness measurement (illustr. 22 / illustr. 25). The analogue value
on the master results from the difference between the measured values of the two sensors. The analogue output of
the slave indicates the distance from the sensor (slave) to the object. Double layers are detected when threshold
values (teach-in of switching points settings 2 and 3) for the thickness of the object have been previously set on
the master.

Communication via the serial interface
All FT 50 RLA ...S1 sensors are equipped with a bus-compatible, serial interface (RS485) for the transmission
of distance values and the setting of sensor functions. The primary control system controls data exchange. Data
transfer occurs through an exchange of short telegrams.
