When buying an (Linear Variable Differential Transformer), the most important features to consider are its frictionless operation , infinite resolution , and extreme durability . These sensors convert linear motion into an electrical signal using a non-contacting core, which eliminates mechanical wear and makes them ideal for high-cycle industrial or aerospace applications. Key Performance Features
: Unlike encoders that may need "homing" after a power loss, an LVDT provides an absolute position signal immediately upon power-up. Environmental & Physical Specifications buy lvdt
: For wet or corrosive environments, look for IP67 or hermetically sealed models to protect internal windings from moisture and contaminants. Environmental & Physical Specifications : For wet or
: Ability to follow rapid movements without lag from friction. : No parts to wear out during operation
: Since LVDTs operate on electromagnetic principles rather than mechanical steps, they can detect infinitesimally small changes in position, limited only by the quality of your signal conditioning electronics.
: No parts to wear out during operation.
: Common ranges span from ±0.1 mm to ±25 cm . Choosing a stroke length that closely matches your application ensures maximum sensitivity. Technical Selection Checklist AC-Operated LVDT DC-Operated LVDT Electronics Requires external signal conditioning Built-in conditioning electronics Complexity Higher; needs separate excitation/demodulation Lower; simple "plug and play" Size Generally more compact Slightly larger to house internal circuitry Stability More stable at extreme temperatures Susceptible to temperature-induced drift
