Displacement Transducers for Triaxial Soil Tester -Image

RDP has pioneered the design and development of linear displacement transducers (LVDTs) suitable for use in triaxial soil testers, where ground samples are subject to pressure applied, most commonly by water or oil.

A triaxial shear test is used to measure the mechanical properties of many deformable solids, especially soil, sand, clay, and other granular materials or powders. Design of the displacement transducer calls for a physically small device, preferably with a through bore permitting cleaning when contaminated with debris, and it is of particular importance that the transducer is waterproof.

RDP has designed a wide range of transducers with different armature and cable configurations to optimise their suitability inside a triaxial test chamber. The LVDTs are available as either unguided or spring return versions.

This transducer uses the Linear Variable Differential Transformer (LVDT) principle which means that it is probably the most robust and reliable position sensor type available. The strength of the LVDT sensor's principle is that there is no electrical contact across the transducer position sensing element which for the user of the sensor means clean data, infinite resolution and a very long life.

LVDT transducers require signal conditioning. This signal conditioning can either be internal (built-in) or external. Our standard external LVDT signal conditioning models are described in the 'Electronics' section of our website.
