NEW! nokra is now part of KELK (VPG)
nokra products will transition to the KELK brandEnd of September 2024 nokra was acquired by Vishay Precision Group (VPG). Starting 2025 the company nokra will be integrated into Vishay Precision Group Canada ULC (KELK) which is part of VPG’s product division “measurement systems”.
KELK supplies high accuracy and performance sensors and systems for the steel and aluminum industries, mainly for rolling mills. The nokra laser geometry measurement systems will be added as a new product line to the KELK product portfolio.
KELK products are focused on 5 main areas of application: 1) rolling force load cells systems and 2) pressure transmitter; 3) tension measurement systems; 4) optical strip width gages; laser velocimeters for strip speed and length measurements, closed-loop crop optimization systems for accurate strip cuts, and 5) Camber Gage to determine centerline positions and true bar shape. Over 70 years KELK products provide high accuracy and reliability under the harsh conditions of the rolling mills in steel and aluminum industries.
As part of this integration, all nokra measurement products will in future be marketed and sold under the KELK brand. The rebranding transition process has just started.

Efficient process management — inline and contactless
The achieved progress and the high speed of developments ensure that laser measuring technology is already revolutionizing inline inspection of geometric sizes today. Flatness, straightness, profile, thickness and width are typical inspection parameters, which are optically measured and hence contactlessly measured directly in the production flow - that is the key competence of nokra.
Our measuring systems inspect seamlessly and automatically in the production cycle. Contactless thickness gauges for strips and plates, or fully automatic flatness inspection systems can be used for the process controlling of quality steel or in the aluminium production. Camshaft inspection machines used in the automotive industry and contour measuring systems for the windshields of automobiles provide an insight into our product range. The results are objective and traceable inspection data, which are provided without any influence of the operator. The automatic feedback of the measured values in the production process increases productivity and efficiency.

Ready for new laser measurement challenges!
The thickness laser measuring system can be used for both, small and wide strips in production or process line.
Optical contour and flatness measurement of plates
Automatically measure the complete contour of each plate optically and scan the flatness with a laser.
