1 Introduction
The PosCon is a competitively priced solution for many applications such as the measurement of
fabric width, monitoring the position of threads or wires, or positioning web edges for example.
The development aim of the PosCon designers was to help end users avoid the complexities
found in the application of many currently available sensing methods. So, the engineers main-
tained a commitment to keeping operation and mounting simple.
In most cases, the measurement of web edge, object width or thickness is carried out by sensing a
particular line established as a point on the moving product. Until now, line cameras have been the
method of choice for such measurements. A line camera, in simple terms, is a video camera that
has a single line of photo-elements instead of a matrix..
The PosCon also uses the principle of inline measurement. However, instead of complex camera
elements, the PosCon utilizes a line of simple photodiodes. This combination of minimal compo-
nents and the commitment to trouble-free set-up and use has helped Baumer develop a product
that performs like an expensive vision system, but retains the cost effectiveness and simplicity of a
sensor.
