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 differential thickness measurement (illustr. 22 / illustr. 23). The analogue value on the master
results from the difference between the measured values of the two sensors. The analogue output of the slave indi-
cates 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 80 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.
INFORMATION
For a convenient parameterisation of the S1 sensor types there is an operating software
„ProgSensor" available for download on our website (www.sensopart.de). In simulation mode, it
indicates the relevant correct bus commands.
If several sensors are connected via the RS485 bus, reflections can occur which may impair
transmission. At the end of the RS485 bus, the cable must therefore be fitted with a resistor
corresponding to the characteristic resistance of the used cable (normally 120 Ohm).
If a sensor is set as master or slave, communication with the PC is not possible.
