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

Abek sensors has been a leading supplier of LVDT (Linear Variable Differential Transformer) and RVDT (Rotary Variable Differential Transformer) position sensors to the aerospace and power generation industry sectors for over 20 years.
LVDT

Abek sensors LVDT's operate using a non-contacting transduction principle, providing friction free motion and infinite resolution. Kavlico has refined this principle through manufacturing and test technology to make our LVDT's the standard for flight and fuel control position measurements. Our success stems from the ability to manufacture matched multiple sensors (channels) for redundancy.

Multiple channels are provided in a variety of housing designs which may be mounted directly on airframe control and cockpit control surfaces or provided as an integral part of a servo valve or main ram actuator.
