Patented NETZSCH State-of-the-Art Technology

Today, we at NETZSCH have the best measuring system for dilatometry. The functional setup of our measuring unit is patented in many countries and features numerous advantages, such as:

  • Unlimited range of the initial sample length and length change at higher resolution
  • Defined low & constant contact force
  • Shock-free and reproducible movement of the pushrod by force control regulation
  • Automatic recognition of the initial sample length

See here for selected dilatometers for a wide range of application fields:

Photo: The DIL 402 Expedis® Supreme represents state-of-the-art dilatometer technology: Automatic sample length determination, constant resolution over a very wide measuring range, and perfect temperature stability of the measuring system along with expanded temperature range thanks to the double-hoist furnace. In addition to this, the measuring system allows for force modulation and thus bridges the gap to thermomechanical analysis (TMA).

The housing of the dilatometer is entirely made of stainless steel. Thus, there are no plastic parts interacting with the samples or the environment.

The Dilatometer Allows for Measurement of a Wide Range of Materials

Today, the dilatometer can be used to measure a variety of materials – from plastics, ceramics and glass to building materials. Changes in glass composition can also quickly and easily be determined by measurement of the thermal expansion coefficients or determination of the glass transition temperature. Furthermore, phase transitions influence the expansion and shrinkage behavior of building materials such as concrete. These have significant impact on the statistical reliability and service life of the systems in which they are used. By means of dilatometry, investigations of dimensional changes like expansion and shrinkage, including volume changes, can be realized. These methods have been successfully employed for decades in industry and research centers, such as the European research center CERN, near Geneva, Switzerland. We look forward to many more decades of dilatometry.

Did you know?

NETZSCH-Gerätebau is also a leader in the field of low-temperature dilatometers to -260°C. These dilatometers are used, for example, for functionality tests on magnetic levitation trains.
