LVDT displacement sensors
LVDT Displacement Sensors
LVDT displacement sensor technology offers high-precision, contactless measurement of linear position and displacement. Engineered for accuracy and reliability, these sensors are fundamental components in demanding industrial automation, process control, and R&D environments where monitoring linear movement is critical.
How LVDT Displacement Sensors Work
LVDT, or Linear Variable Differential Transformer, sensors utilize electromagnetic induction to detect linear movement with remarkable resolution and repeatability. The sensor consists of a primary coil, two secondary coils, and a movable ferromagnetic core. As the core shifts position, the output signal changes in proportion, allowing for precise feedback of displacement over time. Because there is no physical contact between the moving core and the coil assembly, wear and drift are significantly minimized, supporting long service life even in continuous industrial use.
Applications
