How does it work?

Why settle for occasional check-ups when you can have real-time insights? Our permanently installed wireless sensors detect even the smallest fatigue cracks in critical locations with magnetic field variations. 

Continuous Monitoring: Sensors are placed at critical points where cracking is most likely or has already been observed.

Wireless: The sensors register changes and transmit the data to a central system.

Secure Storage and Analysis: Data is securely held and analyzed to identify maintenance needs.

"Villari sensors: a perfect extension of our lifespan analyses

Engineering firm Iv successfully applies Villari sensors as a valuable addition to our fatigue calculations and lifespan analyses. Upon completing a lifespan calculation, we identify crucial points in the construction that require attention, and monitoring often proves to be an appealing solution. It's a pleasure to collaborate with the Villari team, who are not only knowledgeable but also flexible in their approach. The dashboard they provide offers us a clear overview of the status of these critical points. This enables us to provide early advice to our clients and, if necessary, schedule repairs as soon as we detect crack formation that we deem high-risk. Furthermore, we have found that using these sensors is often a financially attractive alternative. Frequent inspections, NDT, or local adjustments to the construction are traditional options, but in practice, these often turn out to be more expensive, especially in hard-to-reach locations."

“With the VILLARI crack sensors, we are increasing the reliability of safety-critical equipment such as cranes in the steel industry”.

In steel industry, the number of ageing assets is steadily rising, and these become more heavily and more frequently loaded to increase productivity.  As such the risk of a component failure and a costly production stoppage is increased.  Whilst it is crucial to frequently inspect the condition of the critical areas of the construction, critical locations are often not easily accessible for executing frequent inspections. Sensors can bring continuous updates of such “health” status in an efficient way.  On ageing installations, the development of cracks is a prime source of concern and often these cracks need to be inspected on a regular basis. But the intensity of the loading activity can change and hence the frequency of the inspections, which is hard to plan, especially in difficult to reach areas. Therefore, the maintenance team benefits from digital assistance to cope with this difficult task.   Being experts on steel and metal related applications including their failures, OCAS NV has therefore partnered up with VILLARI.  Their crack sensors are efficient to install and allow a remote monitoring of the activity levels of the cracks through a graphical user interface.  As such the asset owner can adapt the maintenance schedule and intervene at the right time to avoid a breakdown of the installation.   OCAS NV supports its customers in the metal processing industry with industrial asset reliability services on the technical aspects of asset integrity such as failure analysis, material related QA/QC procedures, determination of critical sensor locations plus measurement follow-up, digital twin simulations and fitness-for-purpose calculations towards remaining lifetime of the critical asset.
