Quick release triaxial cell Load Frame triaxial systems Instruments

The Quick release triaxial cell Load Frame triaxial systems Instruments allows fast and easy testing of specimens with diameters ranging from 21.5 mm (EX) to 54 mm (NX). The specimen and top & bottom platens are fitted in a heat-shrinkable sleeve. The assembly is then lowered and centered in the cell by means of a guiding tool. Once this has been achieved three lateral actuators instrumented with pressure-compensated LVDTs are brought into contact with the sleeve to precisely measure diametral strains. Axial strains are measured with two averaging vertical LVDTs. The QRT series cell shall be implemented in a system encompassing an external axial load actuator such as a load frame and one or more high pressure pumps to inject fluids and apply confining pressure.
