Product Overview
-
Brand: Bently Nevada
-
Series: 3500 Series Machinery Protection & Condition Monitoring System
-
Model: 3500/25M 149369‑01
-
Type: Enhanced Keyphasor Module (2‑channel, Half‑height)
Product Description
The 3500/25M 149369‑01 is an enhanced Keyphasor module engineered to generate accurate and robust phase reference signals for rotating machinery monitoring. It accepts inputs from proximity probes or magnetic pickups and produces digital pulse signals when the key-phase mark on the shaft aligns with the sensor.
Designed for reliability, this upgraded version retains full compatibility with previous module designs, making it seamless to integrate into existing systems. It enhances diagnostics for imbalance, misalignment, and other dynamic faults by enabling precise phase-coherent vibration analysis within the 3500 framework.
Applications
Used across sectors where precise speed and phase synchronization are vital:
-
Steam & gas turbines (blade-pass detection, phase tracking)
-
Compressors and pumps (surge/stall diagnostics)
-
Large motors, generators, and marine propulsion systems
-
Petrochemical and power generation rotating equipment monitoring
Product Advantages
-
Provides 1 or 2 key-phase pulses per revolution, configurable for system flexibility
-
Configurable pulse width for optimized integration with varying systems
-
Operates across -40 °C to +70 °C with industrial-grade reliability
-
Fully downward-compatible—fits and functions just like earlier modules
-
Sturdy design ensures stable performance in harsh industrial environments
