NanoEye ‒ The Technical Revolution of the Dilatometer’s Measuring Cell

What distinguishes a conventional measuring cell from the state-of-the-art NETZSCH NanoEye for dilatometer measurements? Find out in this article.

By Fabian Wohlfahrt, Head of Mechanical Engineering

Material innovation is an essential driving force of the 21st century. Research and development of innovative materials always expand their application fields and resource-efficient use in technical structures. This general trend towards the further development of materials leads to higher demands on the measuring instruments which determine the corresponding material parameters.

In the field of dilatometry, the length changes of thermally influenced materials are analyzed. For example, the future and partly current metrological requirements of materials, specifically soft materials, can no longer be reliably met with the existing technical possibilities. This calls for action regarding design development.

By considering state-of-the-art, requirements for further development are inferred. Reduction of significant disturbance impacts on the length change of the specimen plays a decisive role within the design development. In particular, the aim is to significantly reduce the influence of the contact force during length measurements and to reduce the influence of manual operation.

Under these aspects, a force-controlled measuring cell for dilatometers, the so-called NanoEye, was developed the functionality of which can be proven by experimental results. A summary of the advantages of this measuring cell shows the outstanding step of this new technical development.
