Woodward 5464-751 Speed ​​Sensor

Product Dimensions：

Woodward is a global leader in the design and manufacture of control solutions for the aerospace and industrial markets. Their speed sensors are critical components used to monitor the rotational speed of turbines, engines, and compressors with high precision and reliability.

Product Detailed Description

Woodward speed sensors generally fall into two primary categories: Magnetic Pick-Up Units (MPUs) and Active (Hall Effect) Sensors.

• Magnetic Pick-Up (MPU): These are passive sensors that do not require an external power supply. They consist of a permanent magnet wrapped in a wire coil. As a ferrous metal object (like a gear tooth) passes the sensor tip, it interrupts the magnetic field, inducing an AC voltage pulse.

• Active Sensors (Hall Effect): These require an external power source. They detect changes in magnetic flux and provide a constant pulse output (usually a square wave), which remains stable even at very low speeds or zero-rpm conditions.

Product Parameters (General Specifications)

Note: Parameters vary by specific model (e.g., 8404 series, 3030 series).

Product Advantages

• High Reliability: Designed for mission-critical environments with no moving parts, leading to a long service life.

• Precision: High sensitivity allows for accurate governing and overspeed protection.

• Durability: Robust stainless steel construction resistant to vibration, shock, and extreme temperatures.

• Versatility: Available in various lengths, thread sizes, and connector types (e.g., MIL-spec, lead wires).

• Low Maintenance: Passive sensors require no external power, simplifying the wiring architecture.

Important Considerations (Precautions)

1. Air Gap Adjustment: The distance between the sensor tip and the gear tooth is critical. If it is too wide, the signal will be weak; if it is too close, the gear may strike and destroy the sensor.

2. Magnetic Interference: Keep high-voltage cables away from sensor leads to prevent electromagnetic interference (EMI) from distorting the speed signal.

3. Correct Wiring: For active sensors, ensuring correct polarity of the DC power supply is essential to prevent internal circuit damage.

4. Cleanliness: Ensure the gear teeth are clean of metal debris, as magnetic particles can stick to the sensor tip and cause false readings.

Product Applications

Woodward speed sensors are used across various industries where precise rotational monitoring is required:

• Power Generation: Monitoring steam and gas turbine speeds for load control.

• Marine Propulsion: Measuring engine RPM on large vessel diesel engines.

• Oil & Gas: Speed sensing for compressors and pumps in hazardous locations.

• Industrial Engines: Used in reciprocating engines for governor speed control and overspeed safety shutdowns.
