Description
Woodward 5462-599F
Technical Specifications:
- Output Type: AC Sine Wave.
- Sensing Air Gap: 0.5mm to 1.5mm.
- Operating Temperature: -40°C to +150°C.
Functional Features:
- Wide Frequency Response: Accurately captures speed from barring gear to overspeed conditions.
- High-Temperature Design: Suitable for installation in high-heat zones of engines or turbines.
- Passive Output: Generates its own induced electromotive force without external power.
Application Scenarios:
Paired with Woodward ProTech 203 overspeed systems, 505 controllers, and mechanical-hydraulic governors across steam turbines, gas turbines, and large diesel generator sets.
Performance Parameters:
- Output Amplitude: > 5V p-p at 1000 RPM.
- Coil Resistance: Approximately 200 – 300 Ohms.
Material Composition:
Seamless stainless steel housing. Internal coils use high-temperature magnet wire, and the core utilizes high-permeability rare-earth permanent magnet materials.
Structural Features:
Cylindrical threaded mounting with aviation connectors or armored shielded cables, offering superior electromagnetic interference resistance.
Working Principle:
As gear teeth and gaps alternately pass the sensor face, they cause periodic changes in magnetic reluctance within the sensor, inducing an AC voltage signal in the coil proportional to the rotational speed.
Installation Requirements:
Strictly maintain the specified air gap between the sensor face and gear teeth during installation. Shielded cables are mandatory.
Usage Precautions:
Avoid installation near strong magnetic fields. Maintain phase consistency in dual-channel systems. Periodically check the air gap, as it may change due to bearing wear.
