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.
