The Woodward 5464-013 is a high-precision 4-channel speed sensor module designed for the MicroNet control platform to provide accurate rotational speed monitoring for turbines, compressors, and engines. Each channel is independently configurable to interface with varying sensor types, ensuring millisecond-level data acquisition for critical overspeed protection and governor control loops within high-reliability industrial environments.
Distinctions from Similar Models
- Channel Density: Unlike standard 2-channel variants, the 5464-013 features 4 dedicated channels, allowing for more comprehensive monitoring of multiple shafts or redundant speed sensing on a single turbine.
- Sensitivity Range: This module supports a broader input sensitivity (starting as low as 200 mV), making it more effective at low-speed detection compared to legacy 5464 series cards.
- TMR Compatibility: Specifically optimized for Triple Modular Redundant (TMR) systems, providing stable frequency-to-digital conversion that is critical for synchronized voting logic between three CPUs.
Product Operation Guidelines
- Shielding Requirements: Speed sensor signals are highly susceptible to noise; use high-quality shielded twisted-pair cabling and ensure the shield is grounded only at the control cabinet end.
- Air Gap Calibration: For MPU-based sensing, ensure the sensor air gap is calibrated according to the mechanical specifications to maintain a signal voltage within the 200 mV to 100 V range.
- Frequency Limits: Do not exceed the 25 kHz input limit; verify that the gear tooth count multiplied by the maximum RPM does not surpass the module’s processing frequency.
- Hot-Swapping Caution: While the MicroNet chassis may support hot-swapping, always verify that the “Ready” LED is in the appropriate state before removing the module to prevent interruption of the control bus.
