    Woodward’s Rotary Variable Differential Transformer (RVDT) position sensors provide unsurpassed reliability and durability for rotary motion sensing applications. RVDTs are commonly used for flight-critical command and feedback applications such as:

     

    • Cockpit Controls 
    • Control Surface Feedback 
    • Flap, Slat, Spoiler, and Horizontal Stabilizer Position
    • Nosewheel Feedback
    • Thrust Reverser and Power Lever Angle (PLA)
    • Reservoir and Cable Transducers

     

    Woodward RVDTs are manufactured using the highest quality winding, drivetrain, and structural materials. Thermally matched material selection ensures long life and performance stability over a wide range of environmental conditions. Woodward offers multi-channel redundancy in tandem (end-to-end) or narrow-package cluster configurations. Integral gearing can provide an extended operating range to 900 revolutions.

    A complete portfolio of rigging options and mechanical interfaces is available for adaptation to suit any installation requirement.
