A high-resolution optical encoder measures and controls angular deflection over exceptionally wide ranges greatly improving traditional oscillation and transient strain-controlled testing performance. The optical encoder allows testing to be started in any position for all test modes, and with no preferred home position in oscillation, tests are seamlessly combined with smooth transition and timely response. 6 THRUST AIR BEARING RADIAL AIR BEARING BRUSHLESS DC MOTOR OPTICAL ENCODER NON-CONTACT TEMPERATURE SENSOR ELECTRONICS LOWER GEOMETRY MOUNT

FRAME, VERTICAL MOVEMENT, AND ALIGNMENT ARES-G2 frame and vertical movement assembly is built to deliver maximum overall stiffness and the most accurate geometry positioning and alignment available. The frame pieces are made of cast ductile iron, providing high strength, optimum damping for high frequency testing, and dimensional stability over a wide temperature range. The transducer mount is held rigidly against the frame by hardened steel cross roller slides. The slides provide smooth vertical movement of the head while maintaining concentricity and parallelism, such as when setting a gap in...

FULLY INTEGRATED FAST DATA ACQUISITION ARES-G2 provides fully integrated fast data acquisition for transient and oscillatory testing using 5 fast data channels. This allows simultaneous collection of angular displacement, torque and normal force in all test modes. The high data sampling rate of 8kHz in oscillation mode provides better resolution of both the magnitude and phase of the measured signals and allows better harmonic resolution accurate evaluation up to the 10th harmonic. TRIOS SOFTWARE AND EXTREME TESTING FLEXIBILITY important new feature of the ARES-G2 is a new level of testing freedom...

PLATE Plate is a smart swap temperature control option providing temperature range of –40 to 180 °C, with a maximum heating rate of and temperature accuracy of +/- 0.1 °C. A platinum thermometer (PRT) sensor is positioned in the middle of the lower plate and ensures accurate measurement and control of sample It is the most common system for standard parallel plate and plate testing of structured fluids. The open design facilitates easy loading and cleaning of geometries. A new optional Solvent Trap Cover accessory is available for use with the Peltier plate. as a solvent trap, (to keep samples...

UV-CURING AND PHOTOCURING ACCESSORY The Photocuring Accessory includes upper tool with reflecting mirror and quartz plate, lower plate, light source mount and collimator, 5mm waveguide and remote radiometer/dosimeter. A high-pressure mercury lamp UV light source is included with the UV-curing accessory. Both accessories can be used with the ARES Peltier and Bath temperature control systems. Disposable plates are available for hard UV coatings that cannot be removed from the quartz plates once cured. For extremely fast reacting UV materials, the fast sampling option allows for data collection rates...
