Description
The
BENTLY 3500/25 125792-01 is a high-performance
keyphasor module designed for the Bentley 3500 Series Machinery Protection System, a cornerstone of industrial condition monitoring. Engineered to accurately detect rotational speed and keyphasor signals in rotating machinery, the
3500/25 125792-01 ensures precise measurement of critical parameters such as shaft position, vibration, and timing events, making it indispensable for reliable machinery protection and performance optimization.
The BENTLY 3500/25 125792-01 serves as a vital component in the 3500 System, converting raw sensor signals into actionable data for machinery health monitoring. Its core functions include:
- Keyphasor Signal Processing: Detects and processes keyphasor signals from proximity probes or optical sensors to establish a reference point for rotational speed (RPM) and phase analysis, essential for synchronizing vibration and displacement measurements.
- Dual-Channel Design: Supports two independent input channels, enabling simultaneous monitoring of two keyphasor sources or redundant sensor setups for enhanced system reliability.
- Wide Sensor Compatibility: Works with Bentley’s 3300 Series proximity probes, inductive speed sensors, and optical sensors, ensuring flexibility in system configuration.
- Real-Time Diagnostics: Features built-in self-test capabilities and sensor fault detection, reducing downtime by identifying issues such as cable breaks or sensor misalignment.
- Industrial Hardening: Designed to operate in harsh environments with resistance to electromagnetic interference (EMI), temperature fluctuations, and mechanical vibrations, meeting industry standards for reliability.
The 3500/25 125792-01 simplifies system integration within the 3500 Series rack, providing a standardized solution for rotational monitoring in critical machinery such as turbines, compressors, and generators.
