Contactless optical
Speed measurement

without mechanical parts


Speedwagon measures the speeds of moving tracks and piece goods in order to monitor, control and regulate production systems. The big advantage: The measurement is non-contact, purely optical, without mechanical components and therefore slip-free. In contrast to measuring wheels and other mechanical processes, Speedwagon achieves a higher measuring accuracy and does not damage the material through mechanical wear. In addition, the system is able to take over a trigger function, i.e. a start pulse for example as an output for marking devices as soon as a previously defined increment value has been reached.

Speedwagon - the wear-free solution for optical measurement

Speedwagon is suitable for almost all materials and surfaces, regardless of whether you produce soft or moist products - even with reflective and smooth glass surfaces, the optical measurement is excellent. The operation is intuitive.


Speedwagon is mounted above/at a position where it can scan the surface of the products or materials. For example, on a rotating shaft, on a moving conveyor belt, on moving objects (continuous foils, cardboard boxes, plates, packaging, etc.).
Since Speedwagon not only works contact-free, i.e. purely optically, but also without mechanical components, the distance to the surface to be scanned is also variable. A maximum distance of 15 - 60 mm is recommended.
Speedwagon "scans" the surface and calculates the detected speed. The determined value can be configured as required so that the speed pulses arrive ideally for the connected device. Integration into existing production lines is simple.

Speedwagon "Connect" operating software - intuitive and stylish.

Future industrial manufacturing

I am convinced that non-contact optical scanning without mechanical parts will become established in speed and length measurement in the next few years.
