An LVDT is an electromechanical sensor used to transform mechanical motion into a variable electrical signal (current or voltage) and is used for measurement of displacement. They function as actuators for automatic control systems or as mechanical motion sensors in measurement technologies.
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.
