Understanding how a Texture Analyser works – Frame deflection

When any Texture Analyser/Materials Testing machine is subjected to a force, the whole system experiences some degree of deflection, including the frame, load cell, probe or grips, couplings, and the sample undergoing measurement.

Steps are taken to reduce this movement as far as possible within the bounds of budget and weight. Reinforcement methods include low flexure structures used in castings (corrugation in extrusions, reinforcement bars or reduced length of cantilever components), linear rails used to prevent torsion, careful choice and installation of load cell, and appropriately tightened internal bolts.
