: For wet or corrosive environments, look for IP67 or hermetically sealed models to protect internal windings from moisture and contaminants.
: There is no physical contact between the movable core and the coil assembly. This leads to:
: 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
: Often housed in stainless steel, LVDTs are resistant to shock, vibration, and extreme temperatures (standard ranges often cover -30°C to +85°C , with high-temp versions reaching +150°C or more).
: 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 : For wet or corrosive environments, look for
: 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.
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 Environmental & Physical Specifications : Often housed in
: Ability to follow rapid movements without lag from friction.
