SICK’s SPEETEC Transcends the Limits in the Monitoring of Movements


Can you imagine the unimaginable? A non-contact motion sensor that is virtually wear and maintenance free, has unprecedented affordability and absolute precision surface measurement for process control and quality inspection? You read right, it has all of those attributes and will pay off in no time at all!

CIMTEC is excited to introduce SICK’s newest product line, SPEETEC. A non-contact sensor with no measuring elements or scales, it reliably determines the length, position and speed of all kinds of objects and surfaces. Whether it be continuous roll materials or single items, paper, plastic, metal, wood or textile. Its advantages are particularly evident for sensitive or soft surfaces, which can be damaged by conventional tactile sensors.

With the SPEETEC non-contact sensor for speed and length measurement, SICK has added a compact, affordable, eye-safe laser surface motion sensor to its portfolio, able to measure a wide range of continuous, web-fed or cut-to-length plastic products down to a resolution of 4µm.

The SPEETEC combines unprecedented affordability with precision surface measurement for process control and quality inspection tasks used in the manufacture of plastic products, including processes such as extrusion of plastic pipes or UPVC profiles, and cut to length of sheet materials. The Class 1 eye-safe infra-red laser light eliminates the need for special guarding or safety measures required by many conventional velocimeters.

The SPEETEC uses the Laser Doppler principle to work at speeds between 0.1 and 10 m/s to measure directly on the material surface with an accuracy of 0.1%, and a repeatability of 0.05%. Typically, Return on Investment can be achieved in under 12 months.

Darren Pratt, SICK’s UK Product Manager, said: “The performance and affordability of the SICK SPEETEC will come as a surprise to many machine builders and manufacturers. It therefore promises to automate in-line measurement processes for process control, quality checking, or cutting at levels of speed or accuracy which would not have previously been possible.”

Product testing and field trials have already shown the SPEETEC to be reliable even when measuring materials with challenging, highly reflective, dark-black or uneven surfaces.

The SPEETEC is easy to mount due to its generous mounting tolerances and compact design, and can be set up in a matter of minutes and does not require any supplementary electronics to process the signal output.  The Laser Doppler measurement is automatically converted onboard the sensor into TTL/HTL signals identical to those of an incremental encoder, so that they can be easily integrated into the machine control system.

SPEETEC at a glance:

  • Ensure a high level of product quality by using optical sensors and avoiding damage and contamination to the surfaces being measured
  • The class 1 laser saves costs as no additional laser protection measures are required
  • High measurement accuracy and reproducibility, including in start-stop operation and at short measurement lengths
  • Optimized productivity and process quality through measurement without slippage
  • Broad range of applications thanks to compatibility with many materials, colors and surfaces
