Web guiding systems
Ultrasound edge sensor FX 5030, FX 5060, FX 5100
The ultrasound sensor is specially designed to detect the edges of material such
as paper, foil or film that are impermeable
to sound. Even on foils with a high and
dramatically fluctuating degree of transparency, the sensor assures reliable web
edge detection.
The integrated LED strip in the receiver
especially, helps the user to manually position the sensor. The display may simply
be switched off when used with light-sensitive materials.
Due to the wide measuring range, no
motor-driven sensor follow-up is necessary when the width fluctuates only minimally. In conjunction with motor-driven
support beams and web center guiding,
a width measuring function is generally
included.

Function
The sensor features four sets of transmitters and receivers that, due to their patented arrangement, provide a measuring
range of +/- 10 mm with a resolution of
0.1 mm. The transmitter produces soundwaves that, depending on the degree of
covering by the web edge, produce lesser or greater degrees of amplitude in the
receivers. The analog voltage is digitalized in the AD converter, the value is subsequently sent to the microprocessor
and, once processed appropriately, output via the CAN interface to the controller.
The sensor is largely impervious to height
fluctuations in the web.
The edge position within the measuring
range is indicated on the membrane keyboard integrated on the sensor which is
also used for parameter setting.
