Thermomechanical analyzers (TMA analyzers) are used to study stress generated by a material subjected to a controlled increase in temperature. Types of stress generated can include expansion, compression, tension, or degree of bending. These analyzers are useful for mechanical analysis of materials including glass, polymers, metals, and ceramics.
A typical thermomechanical analyzer consists of a sample chamber surrounded by a furnace. Sample deformation can be measured with a Linear Variable Differential Transformer (LVDT) detector and specialized probes are used to measure thermal expansion (CTE), penetration, and tension. Considerations for purchasing a thermomechanical analyzer include the instrument’s temperature range, sample dimensions, suitability for specific sample types and measurements, and ease of use.

Features
High Precision TMA
The TMA-60 series incorporates a newly developed digital high The TMA-60 and TMA-60H are each uniquely capable of performing a variety of thermomechancial experiments, on an array of sample shapes and sizes, over a wide temperature range, to meet all of your TMA needs!
Features
High Precision TMA
The TMA-60 series incorporates a newly developed digital high-precision displacement sensor that provides dramatically increased measurement accuracy over previous models using LVDT technology. This new detector enables the TMA-60 series to measure displacement in the ±5mm range, twice that of the previous model, for detection of extremely small or large sample deformation.
Easy Operation
The easily replaceable sample support tube and plug-in temperature sensor facilitates effortless operator interchange of test method jigs allowing for rapid transition between elongation and expansion modes of operation.
Customized Measurement Methods
The multifunctional TMA-60 is the best model for expansion, elongation, and penetration measurements while the TMA-60H (high-temperature model) is best suited for differential thermal expansion measurements of ceramics and other materials with minute expansion properties.
Specifications
Temperature Range: TMA-60: Ambient to 1,000°C (for expansion masurement), ambient to 600°C (for tension and penetration measurement in an inert gas), -150°C to 600°C (when using the LTB-60 cooling furnace); TMA-60H: Ambient to 1,500°C

What sets the TMA 402 F1/F3 Hyperion® apart is the modular concept of interchangeable furnaces covering the temperature range from -150°C to 1550°C, which are also compatible with other NETZSCH instruments. A large number of sample holder types and adjustment possibilities are available. The TMA 402 F1/F3 Hyperion® can be operated with a broad range of force, without added weight, digitally programmable from -3 N to 3 N.
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).
Simultaneous measurement of force and displacement signal
The force operating on the sample is generated electromagnetically in the TMA 402 Hyperion®. This guarantees a quick response time for experiments with a changing load, e.g. tests on creep behavior. A highly sensitive force sensor (digital resolution < 0.01="" mn)="" continuously="" measures="" the="" force="" exerted="" via="" the="" push="" rod="" and="" readjusts="" it="" automatically.="" this="" sets="" the="" tma="" 402="" /> Hyperion® apart from other instruments, which use only preset values.
Vacuum-tight thermostatic measuring system
The entire TMA 402 F1/F3 Hyperion® measuring system is thermally stabilized via water-cooling. This ensures that the measurement will not be influenced by heat from the furnace or by temperature fluctuations in the local environment. All joints have a vacuum-tight design to allow measurements in a highly pure atmosphere or under vacuum. Pressures of less than 10-4 mbar can be achieved in the TMA 402 F1/F3 Hyperion® with the use of a turbo molecular pump. In combination with the integrated mass flow controllers (MFC) for purge and protective gases (optional in the TMA 402 F3 Hyperion®), measurements in highly pure inert gas or in oxidizing atmospheres can be optimally controlled.
Precise force control
The electronic control system for the TMA 402 Hyperion® allows forces to be set in the mN-range. This enables testing even on sensitive materials such as thin fibers or films. The force operating on the sample can be altered via the software in a stepwise or linear fashion. This makes it particularly simple to carry out such analyses as creep or stress sweep tests. The premium version of the TMA 402 Hyperion®, the TMA 402 F1 Hyperion®, provides even more capabilities. From single pulse in rectangular or ramp form to continuous modulation with a freely selectable frequency (up to 1 Hz), every possibility is covered. This model is particularly well-suited for determining visco-elastic material properties such as elasticity and creep modulus.... Read More |
