Captures and conditions keyphasor pulses from proximity probes (eddy-current type) or optical encoders installed on rotating equipment (e.g., turbines, motors, compressors, pumps). It processes raw signals to extract accurate rotational position (angular reference) and real-time speed (RPM), laying the foundation for phase-correlated measurements like vibration analysis.
Internal Termination Integration
Features built-in internal terminations that eliminate the need for external junction boxes, simplifying wiring layouts, reducing installation time, and minimizing signal loss/electromagnetic interference (EMI) in industrial environments—enhancing overall system reliability.
System Synchronization
Seamlessly communicates with the 3500 Series rack backplane to synchronize keyphasor data with other monitoring modules (vibration, temperature, pressure). This time-aligned data integration enables comprehensive machinery condition assessment, such as correlating vibration anomalies with specific rotational positions.
Configurable Signal Adaptation
Supports customization via Bently Nevada 3500 Rack Configuration Software, allowing users to adjust pulse thresholds, filtering parameters, and signal processing logic to match diverse machinery types and operating conditions (low-speed to high-speed rotating equipment).
Data Transmission & Integration
Transmits processed keyphasor data to the 3500 rack processor and host software (e.g., System 1®) for real-time monitoring, trend tracking, and alarm generation. Facilitates early detection of mechanical faults (imbalance, misalignment, bearing wear) by providing consistent reference data for condition analysis.
Self-Diagnostic & Reliability
Incorporates built-in self-diagnostic functions to monitor module health, power status, and signal integrity. Delivers status feedback via visual indicators, ensuring quick fault identification and minimizing unplanned downtime for critical machinery.
Characteristics
Operating Temperature Range: -40°C to +70°C (-40°F to +158°F), suitable for extreme industrial environments (power plants, oil refineries, petrochemical facilities).
Power Requirements: Operates on 3500 Series rack power supply (24 VDC ±10%), with low power consumption (<5 W) for energy efficiency.
