In the field of rock mechanics testing, rock triaxial tests serve as a core method for investigating rock mechanical properties, supporting engineering design, and conducting scientific research; meanwhile, the precise measurement of displacement and strain is a critical factor in ensuring the reliability of test data. As high-precision displacement/strain measurement sensors, LVDTs (Linear Variable Differential Transformers) have been widely adopted throughout the entire rock triaxial testing process due to their high measurement accuracy, excellent stability, and superior resistance to interference, serving as the core measurement components that link test loading with the calculation of mechanical parameters. ABEK SENSORS’ FCXA10 series of miniature LVDT sensors can directly measure minute axial and radial strains on test specimens. With a temperature resistance of up to 200°C and a pressure resistance exceeding 140 MPa, these products are suitable for a wide range of complex testing scenarios.

For most applications of linear variable differential transformer (LVDT) position sensors, standard LVDTs can meet operational requirements. However, in certain specialized high-pressure environments, more stringent conditions demand enhanced protection and adaptability from LVDTs. This necessitates design considerations and customized modifications tailored to specific application scenarios. This article focuses on various high-pressure applications, detailing LVDT adaptation solutions and corresponding strategies.
