Facility Features, Working Principle and Specifications
Working Principle
Rheology is the study of flow and deformation of materials. Deformation and flow are referred to as strain or strain rate, respectively, and indicate the distance over which a body moves under the influence of an external force, or stress. For this reason, rheology is also considered to be the study of stress-strain relationships in materials. A rheometer is a precision instrument that contains the material of interest in a geometric configuration, controls the environment around it, and applies and measures wide ranges of stress, strain, and strain rate.Material responses to stress and strain vary from purely viscous to purely elastic to a combination of viscous and elastic behaviour, known as viscoelasticity. These behaviours are quantified in material properties such as modulus, viscosity, and elasticity.
Features
ARES-G2
The ARES-G2 provides independent measurements of stress and strain. The ARES-G2 is the only Separate Motor and Transducer (SMT) rheometer in the world. An SMT is more than two drives. It is a separate motor and transducer optimized for every aspect of rheological measurement. A motor designed for perfect deformation. A transducer optimized for exacting stress measurements. The result is the purest rheological measurements, free of instrument artefacts over the widest ranges of stress, strain and frequency. The ARES-G2 Torque Rebalance Transducer (TRT) is the third generation of rebalance transducers designed and optimized exclusively for the most exacting measurements of sample stress. The ARES-G2 incorporates patented non-contact temperature sensor technology for active measurement and control of both the upper and lower plate temperature.
MCR 702
MCR 702 MultiDrive as a CMT (Combined Motor Transducer) rheometer with a single EC motor . Performing ‘classic’ stress-controlled tests. Signal from encoder and torque from upper motor to calculate rheological properties. Connection of all temperature devices and application-specific accessories of the MCR rheometer series possible. Compliance calibration is done as part of calibration. Temperature control of air bearing responsible for long-lasting torque and normal force accuracy. Both motor units are employed in a synchronized fashion. One motor (upper) is brought to a fixed position and operated solely as a torque transducer. Offer Zero Compliance. One motor (lower) operates as a drive unit. Speed or angle from bottom motor and torque from upper motor are used to calculated rheological properties. Software displays the physical properties of both motors.
