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 incorporates patented non-contact temperature sensor technology for active measurement and control of both the upper and lower plate temperature (Patent # 6,931,915).
Platinum Resistance Thermometers (PRTs) are positioned in intimate contact with the center of the lower and upper measurement surfaces and transmit temperature readings to the instrument wirelessly. These temperature readings enable direct control of both plate temperatures and result in more accurate and responsive temperature control, no vertical temperature gradients and no need for complex calibration procedures and offset tables to infer sample temperatures.
