The HT1600 furnace is designed to perform impulse excitation measurements at elevated temperatures up to 1600 °C in an air atmosphere or with an inert gasflow (optionally). Measurements can be performed in predefined intervals during heating and cooling (1-5 °C/min) in order to determine the elastic properties and damping as function of the temperature. The adjustable positioning of the excitation system and microphone and the bottom loading of the sample guarantee an optimal sample configuration and manipulation. Optionally, a dilatometer can be mounted on the system to measure the linear expansion simultaneously with the elastic properties.

General Description:

Enhance the capabilities of the RFDA HT1600 with the option to mount a dilatometer on the furnace. This innovative feature enables simultaneous impulse excitation measurements on one sample and dilatometer measurements on another sample within the same temperature cycle.
The dilatometer precisely measures dimensional changes in a specimen, offering valuable insights into physical and chemical processes occurring within the material. By accurately determining linear dimension changes, researchers can studie the causes of these changes.

With the integration of the dilatometer, the HT1600 offers a comprehensive platform for advanced material analysis, enabling researchers to gain deeper insights into the behavior of various materials under diverse conditions.

Key Applications:

  • Thermal Expansion Studies: Analyze materials’ response to temperature variations.
  • Annealing Studies: Investigate the effects of annealing processes on sample properties.

IMCE’s advanced programmable measurement cycle upgrade enables users to pre-define measurement settings in function of temperature throughout the entire measurement cycle. This enhancement grants users more control over the measurement process in advance. For instance, it enables automatic switching of the measurement interval, seamlessly transitioning from delta temperature (during heating and cooling phases) to delta time (during dwell times). Additionally, users can precisely increase impulse power within specific temperature ranges.

This upgrade offers our customers the capability to attain exceptional measurement results, even under extreme temperatures. By providing a sophisticated level of customization, it ensures high-quality, accurate data collection, reinforcing IMCE’s commitment to maximize you testing capabilities.

The upgrade offers following customization options:

  • Automatic switching of measurement interval: Users can pre-define the measurement interval per temperature segment (Delta temperature or Delta time).
  • Impulse force: Adjustable impulse force for precise measurements in each temperature segment.
  • Signal filters: Customizable signal filters for data accuracy.
  • Temperature segments: Users can add, split, and remove temperature segments for precise control of inert gas flow, especially in critical temperature ranges.
  • And many more
