RVDT 既旋轉可變差動變壓器縮寫，屬于角位移傳感器。它采用與LVDT 相
同的差動變壓器式原理，即把機械部件的的旋轉傳遞到角位移傳感器的軸上，帶
動與之相連的擾流片/ 鐵芯，改變線圈中的感應電壓/ 電感量，輸出與旋轉角度
成比例的電壓/ 電流信號。
RVDT 非接觸設計，具有無限分辨率、使用壽命長，精度高的特點，可實現
360°轉動測量。

SOLUTIONS TO IMPROVE AIRCRAFT EFFICIENCY

The legacy of ABEK SENSORS aviation innovation includes our advanced technology in position sensors. From the cockpit to control surface, our rotary sensors provide multiple aviation solutions. Continued improvement for performance in increasingly harsh environments keeps us at the forefront of driving aircraft efficiency.

SENSING TECHNOLOGIES INCLUDE:

• Inductive (RVDT, Resolver)

Common applications include fly-by-wire flight control systems, engine control systems and vehicle health management. Our products are usually developed from a custom set of requirements, however some key features include:

• Up to four redundant channels
• In-line or cluster configurations
• High speed shaft sealing available
• Gearhead allows absolute measurement over >300 input shaft revolutions
• Accuracy better than 0.25% full scale deflection
• Lane to lane tracking better than 0.5% full scale deflection

APPLICATIONS:

• High lift system position and asymmetry sensing
• Environmental control system valve position
• Missile fin position
