What is the range of LVDT?

The linear variable differential transformer (lvdt) displacement transducer delivers competent real-time measurement of sliding armature position change between the spring mechanism and the exterior housing. This rugged device provides superior metrics for live load displacement and temperature effects on structural components based on years of proven performance on bridges and building structures and hydraulics.

specific application and design. The overall range classification for LVDT measurements includes three categories: Small Range: ±0.1 mm to ±2.5 mm Medium Range: ±2.5 mm to ±50 mm Large Range: ±50 mm to ±500 mm (and sometimes beyond) Certain specialized LVDTs exist which can measure displacements extending from ±1 meter into larger distances though such systems remain not widely used. The operating distance of an LVDT depends on its coil design combined with core material selection and the anticipated use application ranging from industrial automation to aerospace to structural monitoring systems.

The measurement range capability of different LVDTs spans from ±100 μm to ±25 cm while the typical excitation voltage range varies from 1 V to 24 V rms with frequency values between 50 Hz to 20 kHz. The linear displacement sensor generates output signals by measuring object distance travel in millimeter (mm) or inch (in.) units and can produce either positive or negative values
