Local Displacement Transducer with Miniature Position Encoder



The article presents the preliminary results concerning the use of miniature magnetic linear encoders for the measurement of displacements at small strains in triaxial soil tests. Presented are: the main principle of operation of this type of sensors, their advantages, and how they have been implemented in a standard triaxial test stand to the existing equipment. Finally, the test results obtained for a soil sample are used to highlight the difference in results obtained with the new sensors compared to linear variable differential transformer transducers.
