Captures high-integrity keyphasor pulses from proximity probes or optical encoders mounted on rotating equipment (e.g., turbines, motors, compressors). The module processes these signals to determine precise rotational position (angle) and speed, serving as a reference for phase-related measurements (e.g., vibration phase analysis).
Internal Termination Design
Features integrated internal terminations that eliminate the need for external junction boxes, simplifying wiring complexity and reducing installation time. This design also enhances signal integrity by minimizing electromagnetic interference (EMI) and signal loss in industrial environments.
System Synchronization
Synchronizes keyphasor data with other 3500 Series modules (e.g., vibration, temperature, pressure modules) via the 3500 backplane. This ensures time-aligned data collection, enabling comprehensive machinery condition analysis (e.g., correlating vibration anomalies with specific rotational positions).
Speed & Position Calculation
Computes real-time rotational speed (RPM) and angular position from keyphasor pulses, with high-resolution processing to support low-speed and high-speed machinery (compatible with a wide range of rotational speeds common in industrial applications).
Fault Tolerance & Reliability
Engineered with industrial-grade components to withstand harsh operating conditions (temperature extremes, vibration, electrical noise). The module maintains signal stability and data accuracy even in demanding environments, ensuring continuous monitoring without false triggers.
System Integration
Seamlessly interfaces with the 3500 Series rack and host software (e.g., Bently Nevada System), transmitting keyphasor data for real-time monitoring, trend analysis, and alarm generation. Supports configuration via the 3500 Rack Configuration Software, allowing users to customize signal processing parameters (e.g., pulse threshold, filtering) to match specific machinery requirements.
Characteristics
Operating Temperature Range: -40°C to +70°C (-40°F to +158°F), suitable for extreme industrial environments (e.g., power plants, oil refineries).
Power Requirements: Operates on 3500 Series rack power supply (24 VDC ±10%), with low power consumption (<5 W) for energy efficiency.
