A Linear Variable Differential Transformer (LVDT) is a linear position sensor that produces an electrical signal proportional to the displacement of a moveable core (armature) within a hollow cylindrically wound coil assembly. The core is attached to the target via an armature extension.

Features

• Linear displacement from .001" to 60"
• Stainless steel construction or lightweight aluminum
• Operating pressures up to 10,000 psi (15.000 psi burst pressure)
• High temperature & vibration environments (per MIL-STD 810 or RTCA DO-160)
• High accuracy (± 0.25% full scale)
• Infinite resolution
• Hermetic designs available
• Linearity (± 0.1% full scale)
• Fault detection
• High reliability (single channel MTBF of 1,000,000 hrs. typical)

Applications

• Flight control actuators
• Valves
• Nose wheel steering systems
• Cockpit controls
• Engine bleed air systems
• Fuel controls
• Fly-by-wire systems
• Brake-by-wire systems
• Environmental control systems
• Also used in Power Turbine Applications
