LVDT
Kearfott’s Linear Variable Differential Transformers (LVDTs) are time tested for more than 50 years for a range of aerospace, military, and other high reliability/harsh environment applications. LVDT position sensors are most commonly used in control surface position applications, pilot controls, and on-engine feedback. Options are available to supply hermetically sealed units for use in fluid and hydraulic applications.
