Pioneering the Skies: LVDT & RVDT Applications in Commercial Aircraft

Wednesday, June 21, 2023

At the heart of modern commercial aircraft lies an intricate network of sensors, each performing a crucial role in ensuring safety, performance, and reliability. Among these, Linear Variable Differential Transformers (LVDTs) and Rotary Variable Differential Transformers (RVDTs) stand out due to their robust design and exceptional performance in harsh environments. Sentech, a leading manufacturer of these indispensable sensors, provides custom yet cost-effective LVDTs and RVDTs that meet the aerospace industry's rigorous demands.

The Core of LVDT & RVDT: Designed for Excellence

At Sentech, the design and manufacture of aerospace-grade LVDTs and RVDTs hinge on the appreciation of the demanding applications and challenging conditions these sensors are subjected to. Our engineering team collaborates closely with our customers, delivering aerospace sensors that not only meet their specific requirements but also provide consistent, accurate measurements over a prolonged operational life.

What sets Sentech's LVDTs and RVDTs apart is their unmatched repeatability and robustness, which make them ideal for deployment in extreme operating conditions. We offer high-temperature and pressurized units designed to fit into many demanding applications. Our RVDTs and LVDTs are perfect for the majority of fly-by-wire systems, which typically require built-in redundancy and single or multi-channel aerospace position sensors.

LVDT & RVDT Applications in Commercial Aircraft

LVDTs and RVDTs are integral to both fixed and rotary-wing aircraft, providing absolute linear and angular position measurements respectively. Here's a closer look at some of the key applications:

Flight Control Actuators: LVDTs and RVDTs are used in a variety of flight control actuators. These include:

Ailerons: Wing flaps that control roll.

Elevators or Stabilizers: Flight controls responsible for the aircraft's pitch.

Rudder: Controls responsible for the yaw motion.

Flaps: Devices used to increase the lift of the wing at a given airspeed.

Spoilers: Devices that decrease lift and increase drag.

Stabilizers: Devices that help maintain the aircraft's equilibrium and control pitch.

Engine Control and Feedback: Our sensors play an essential role in providing on-engine feedback and controlling various engine aspects. These include Thrust Reverse Actuators (TRAS), Auxiliary Power Unit (APU) controls, engine bleed air systems, and fuel controls.

Cockpit Controls: Sentech's LVDTs and RVDTs are used extensively in the cockpit, providing critical feedback for pilot controls.

Fly-by-Wire and Brake-by-Wire Systems: Our sensors form the cornerstone of these systems, translating the pilot's commands into electronic signals that control various aircraft functions.

Landing Gear and Steering: Sentech's LVDTs and RVDTs provide critical feedback for landing gear systems and nose wheel steering systems, ensuring safe takeoffs, flights, and landings.

Compliance and Quality Assurance

Ensuring the highest level of reliability and durability, our LVDTs and RVDTs are manufactured in accordance with RTCA-DO-160 and MIL-STD-810, offering long-term life requirements. We offer both AC and DC units, thus offering a variety of options to meet your specific needs.
