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.

LEADING THE MARKET IN POSITION SENSOR INNOVATION

For over 20 years, abek sensors has led position sensor development in the aerospace industry. From researching the most advanced materials available, employing no-contact designs and highly skilled manufacturing practices, our products meet the most stringent demands of performance, size and quality.
