Description of the sensor functions

Ultrasonic double-sheet monitoring to detect splice points is used in all situations in which
an automatic distinction must be made between splice points and double sheets in order
to protect machines or avoid waste production. Double-sheet monitoring for splice point
detection is based on the ultrasonic through-beam principle. The following can be detect­ed:

- No sheet

- Individual sheet

- Splice point or double sheet

A microprocessor system evaluates the signals. The appropriate switch outputs are set
as a result of the evaluation. Changes in ambient conditions such as temperature and
humidity are automatically compensated. The evaluation electronics are installed in a
cuboid plastic housing separate from the sensor heads.

Measuring system

A complete system consists of an ultrasonic emitter, an ultrasonic receiver and an eval­uation unit. These units have been optimally tuned to one another at the factory and may
not be used separately.

Alignment

When adjusting the emitter and receiver, take care to align them as precisely as possible.
Distance of the sensor heads: d = 20 mm ... 80 mm

Angular tolerance: α < +/- 2°
Maximum offset: s < +/- 2 mm

To ensure their correct function, the sensor heads must be aligned at an angle of
20° ... 45° from vertical onto the paper surface. The paper is guided over the emitter at a
distance of 5 mm ... 15 mm. The emitter is installed below in order to prevent dust depos­its. Install the sensor heads using the included plastic nuts. The sound cone must be
completely covered by the paper. This means that the sensor heads must be installed
above the sheet of paper and at least 10 mm away from the side edge of the paper.
