The Bently Nevada 3500/45 176449-04 is a high-performance 4-channel position monitor from the 3500 Series machinery protection system. This module is designed to accept inputs from a wide variety of position transducers — including proximity probes, Rotary Position Transducers (RPTs), DC/AC LVDTs, and rotary potentiometers — and provide continuous, real‑time monitoring of critical position parameters.
The 176449-04 is a main board module that must be paired with a compatible I/O module (e.g., 135137-01 for internal terminations) to form a complete position monitoring solution. It is widely deployed in power generation, oil & gas, and heavy industrial facilities for monitoring turbines, compressors, and other large rotating machinery.

The 3500/45 can be configured via 3500 Rack Configuration Software to perform multiple position measurement functions:
| Function | Description |
|---|---|
| Axial (Thrust) Position | Monitors axial movement of a shaft to prevent thrust bearing damage |
| Differential Expansion | Measures relative growth between machine casing and rotor |
| Case Expansion | Monitors thermal expansion of the machine casing |
| Valve Position | Monitors opening/closing position of steam, fuel, or process valves |
| Dual Ramp Differential Expansion | Provides advanced expansion measurements for complex machinery configurations |
The 3500/45 integrates into the Bently Nevada 3500 Series ecosystem:
Required Components:
Main Board: 176449-04 — The monitor module itself
I/O Module: Must be paired with a compatible I/O module such as 135137-01 (internal terminations) or similar
3500 Rack: Installs into one full-height front slot
Configuration:
Programming is performed using 3500 Rack Configuration Software (v2.41 or higher)
Channels can be paired to perform different measurement functions simultaneously
System Integration:
Supports integration with DCS, SCADA, and plant information networks via 3500 communication modules
Recorder outputs provide 4-20 mA signals for external monitoring systems
The 3500/45 Position Monitor is essential for critical rotating machinery protection across multiple industries:
| Industry | Application |
|---|---|
| Power Generation | Steam and gas turbine axial thrust monitoring, differential expansion during start‑up/thermal cycles |
| Oil & Gas | Centrifugal compressor rotor axial position monitoring, pipeline pump protection |
| Chemical Processing | Compressor and pump position monitoring in hazardous areas |
| Hydroelectric | Wicket gate position measurement, runner axial displacement monitoring |
Key Machine Types
Steam and Gas Turbines
Centrifugal and Reciprocating Compressors
Industrial Pumps
Generators
Gearboxes
Turbo‑expanders
The 176449-04 is the main board only. It must be used with a compatible I/O module (such as 135137-01) to be fully functional. The I/O module provides the physical termination points for sensor wiring.
TMR Applications: In Triple Modular Redundant (TMR) configurations, Valve Position measurements are generally not supported.
