Rheological measurements made in oscillation in general operate on strong signals, both stress and strain. With increasing complexity of materials, the need exists to cover wide ranges in sample modulus (and hence stress and strain) during a single measurement. For dynamic ranges better than 106, random noise has to be eliminated and systematic errors corrected in order to insure accurate results. Fast data acquisition combined with a flexible correlation technique is required to improve the low end performance of an oscillatory rheometer. The harmonic analysis of large strain amplitude oscillation tests is becoming a very useful technique to characterize subtle differences in materials’ structure. A fast data acquisition is a must for the determination of magnitude and phase of the higher harmonic response in a non linear oscillation test. UV curable adhesives and coatings change from a low viscosity fluid to an elastic solid within seconds. Fast data sampling associated with a flexible window correlation method can provide up to 100 data points per second – thus allowing an accurate monitoring of rapid changing processes.
