LVDT

LVDT

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.
