TA Instruments ElectroForce DMA 3200

TA Instruments’ ElectroForce DMA 3200 Dynamic Mechanical Analyser provides new capabilities for testing of physically larger and stiffer specimens, and over wider ranges of deformation. For example, a composite sample for which the specimen must be large to guarantee test results that are representative of the total macrostructure. It may not be feasible or advisable to cut this material small enough for a lower-force DMA instrument without compromising its structural integrity and impacting material properties.

Dynamic mechanical analysis (DMA) is a technique used to characterise viscoelastic behaviour of materials as a function of force, strain, time and temperature. This technique quantifies material parameters such as modulus (stiffness) and damping or energy absorption over a range of loads, temperature and time. The latest instrument complements TA’s DMA850 and RSA-G2 DMA products, enabling both DMA and fatigue testing to a maximum force of 500 Newtons, which is over 10 times higher compared to lower-force offerings.

DMA3200 combines core technologies from both ElectroForce and TA Instruments. Linear motion is applied by the powerful and durable ElectroForce motor derived from Bose Corporation’s high-performance electromagnetic speaker technologies. Precise temperature control is achieved through the Forced Convection Oven (FCO), a system popularised through use in the research-grade RSA-G2 and ARES-G2 and designed by TA Instruments’ thermal design experts.  Finally, the instrument’s new control algorithms and analysis software are designed to deliver precise and reliable results for users.
