Description
The Linear Variable Differential Transformer (LVDT) displacement transducer accurately measures the movement between the spring-loaded sliding armature and the exterior body. These rugged and self-contained units are ideal for recording displacements on structural members due to live loads and temperature variations.
With years of experience using these transducers on bridges, building and hydraulic structures they are the gold standard when it comes to very accurate position measurements.
