RVDT 既旋转可变差动变压器缩写，属于角位移传感器。它采用与LVDT 相
同的差动变压器式原理，即把机械部件的的旋转传递到角位移传感器的轴上，带
动与之相连的扰流片/ 铁芯，改变线圈中的感应电压/ 电感量，输出与旋转角度
成比例的电压/ 电流信号。

 RVDT 非接触设计，具有无限分辨率、使用寿命长，精度高的特点，可实现
360°转动测量。

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
