Product Overview: Bently Nevada 3500/25 125792‑01 Enhanced Keyphasor Module
The 3500/25 125792‑01 is an enhanced Keyphasor® signal-conditioning module from the 3500 machinery protection system. It processes input from proximity probes, magnetic pickups, or optical sensors and generates precise phase-reference pulses synchronized to shaft rotation. Designed for demanding industrial environments, it enables accurate vibration phase analysis, speed tracking, and real-time fault detection.
Brand and Series
-
Brand: Bently Nevada
-
Series: 3500 Machinery Protection System – Keyphasor signal conditioning modules
Applications
This module is essential for applications requiring precise phase reference in rotating machinery, including:
-
Turbine vibration and blade-pass analysis
-
Compressor surge/stall detection
-
Pump cavitation and misalignment diagnosis
-
Generator eccentricity and alignment monitoring
-
Marine propulsion shaft torsional vibration tracking

Harsh environments such as offshore platforms and Arctic or desert installations
Key Features & Advantages
-
Phase‑accurate signal output allows reliable 1× RPM synchronization and phase-based diagnostics.
-
Dual‑sensor redundancy and voting logic mitigate single-channel failures.
-
Configurable pulse width (5°–330°) and adjustable filters (low-pass and notch) enhance signal fidelity.
-
Built‑in diagnostics via LEDs and adaptive conditioning ensure signal health monitoring.
-
Hot‑swappable design facilitates maintenance without interrupting system operation.
-
Ruggedized build, extensive temperature rating, and safety compliance (SIL 2, API 670) ensure reliability in extreme conditions.
