Dilatometers RSS Feed - Dilatometers

Dilatometers are used to measure the thermal expansion of a material. By measuring how much a material expands as a function of temperature, the thermal expansion co-efficient can be calculated. The thermal expansion co-efficient (typically expressed in m/m. degrees C) is a useful parameter to know if a material is going to be subject to large temperature variations in its service life. A dilatometer typically consists of a furnace to heat the test sample and a measuring device which may be mechanical or optical in nature.

The DIL 2012 STD dilatometer available from Orton is used for Thermal Dilatometer Analysis (TDA), also called as dilatometry.
The new dilatometer DIL 402 Expedis Select and Supreme offer state-of-the-art dilatometer technology and are desiged for a wide range of sophisticated applications. All instruments of the DIL Expedis series feature the revolutionary NanoEye measuring cell; a new dimension in measuring range and accuracy.
TA Instruments’ DIL 806 optical dilatometer is an advanced and versatile tool designed for thermal expansion and contraction measurements. It is perfectly suited for measuring thin, irregularly-shaped soft sample lengths without contact.
Orton offers the DIL 2016 STD dilatometer, which is often used for Thermal Dilatometer Analysis (TDA).
The TMA 801 operates in a vertical orientation, making it ideal for the analysis of sintering, RCS (rate controlled sintering), viscoelastic behavior and the determination of softening temperatures. The linear motor generates a constant throughout the experiment, ensuring that contact is maintained with the sample regardless of dimension change.
The new dilatometer DIL 402 Expedis Classic represents a robust and easy-to-use all-in-one instrument. All instruments of the DIL Expedis series feature the revolutionary NanoEye measuring cell; a new dimension in measuring range and accuracy.
Preiser Scientific's new 6000 Series of Plastometer/Dilatometer controllers provide for great flexibility by allowing two tests to be run with only one controller.
The heart of the TMA 402 Hyperion® is a highly precise inductive displacement transducer (LVDT). This technology has stood the test of time; it is also used for dilatometers and allows measurement of even the smallest of length changes, into the nanometer range (digital resolution of 0.125 nm).
Suitable for the widest range of routine thermal expansion measurements, the DIL 801 and DIL801L are horizontally configured single-sample dilatometers. The DIL 801 is designed for measurements under vacuum or inert gas while the DIL 801L is designed for measurements in air, making the DIL 801L ideally suited to measuring ceramic materials which are often processed in air.
TA Instruments’ DIL 802/802L differential horizontal dilatometer has been specifically designed to provide accurate differential measurement. It measures the difference between the sample and the inert reference.
Orton dilatometers are designed to measure the dimensional changes of ceramics, glasses, metals, carbon composites, cermets, minerals, and polymers as a function of temperature.
To maximize sample throughput, the DIL 803/803L offers two-sample simultaneous operation in a horizontal dilatometer. The DIL803/803L can also be operated with an inert reference sample for differential measurement, reducing the influence of measurement system expansion and increasing measurement accuracy under dynamic temperature conditions.
TA Instruments’ DIL805A/D is a unique dilatometer designed for determining the deformation parameter and for creating continuous cooling, TTT-, and DTTT- diagrams.
Orton offers DIL 2010 STD dilatometer that is typically used for dilatometry or Thermal Dilatometer Analysis (TDA).
