Description

Woodward 5464-541 Position Sensor

Product Dimensions：

Woodward is a global leader in the design and manufacture of high-precision control solutions. Their Position Sensors, particularly their Linear Variable Differential Transformers (LVDTs) and Rotary Variable Differential Transformers (RVDTs), are industry standards for aerospace and industrial applications.

Here is a detailed product overview in English.

1. Product Description

Woodward position sensors are rugged, non-contacting devices used to measure the linear or angular displacement of critical components. Because they rely on electromagnetic coupling rather than physical contact (like a potentiometer), they offer near-infinite resolution and an extremely long operational life.

• LVDT (Linear Variable Differential Transformer): Used for straight-line motion sensing (e.g., pilot valve position).

• RVDT (Rotary Variable Differential Transformer): Used for angular or circular motion sensing (e.g., cockpit controls or throttle levers).

2. Key Technical Parameters

While specific parameters vary by model (e.g., the 3151 series or the 8200 series), typical specifications include:

3. Product Advantages

• High Reliability: The non-contact design eliminates mechanical wear, making them ideal for mission-critical “fly-by-wire” systems.

• Redundancy: Woodward often provides multi-channel (Dual, Triple, or Quadruple) designs within a single housing to ensure system safety.

• Environmental Resilience: Hermetically sealed options are available to withstand fuel, oil, hydraulic fluid, and extreme humidity.

• Accuracy: Exceptional repeatability and low hysteresis even under varying thermal conditions.

• Compact Integration: Custom-engineered shapes allow them to be integrated directly into hydraulic actuators or cockpit pedestals.

4. Applications

Woodward position sensors are primarily found in high-performance environments:

• Aerospace: Flight control surfaces (flaps, slats, ailerons), engine fuel control systems, and cockpit linkages.

• Power Generation: Steam and gas turbine valve positioning (IGV – Inlet Guide Vanes).

• Industrial: Heavy-duty hydraulic cylinder positioning and precision manufacturing equipment.

• Marine: Engine room automation and steering gear feedback.

5. Important Considerations (Precautions)

• Excitation Alignment: Ensure the input frequency and voltage match the sensor’s calibration; incorrect excitation can lead to overheating or signal inaccuracy.

• Magnetic Interference: Since these are electromagnetic devices, avoid mounting them in immediate proximity to strong, unshielded permanent magnets.

• Null Position: Proper mechanical alignment to the “Electrical Null” (the point where output voltage is zero) is critical during installation for balanced sensitivity.

• Wiring Integrity: Use shielded twisted-pair cabling to prevent EMI (Electromagnetic Interference) from distorting the low-voltage output signals.
