Product Introduction: 3500/60-01-00
The 3500/60-01-00 is a Vibration Monitor (Torsional) module for the Bently Nevada 3500 Machinery Protection System. Unlike standard vibration monitors that measure lateral or radial vibration, this specialized module is designed to detect, monitor, and protect against torsional vibration in rotating shafts. Torsional vibration is the oscillatory twisting of a shaft along its axis of rotation, which is often difficult to detect but can lead to catastrophic shaft failure. The 3500/60 module analyzes speed pulse signals to calculate torsional vibration levels, providing critical alerts and shutdown signals to prevent damage to couplings, gears, and the shaft itself.
Technical Parameters

| Parameter Category | Specification |
|---|---|
| Model & Part Number | 3500/60-01-00 |
| Module Type | Torsional Vibration Monitor |
| Input Signal | Speed probe signals (typically from dual probes on a dedicated gear). |
| Input Channels | 2 speed input channels (for a single shaft). |
| Measurement Range | User-configurable, typically in degrees peak-to-peak or strain. |
| Frequency Range | Torsional vibration frequencies from 0.5 Hz to several hundred Hz. |
| Module Dimensions (H x W x D) | Approx. 190 mm x 60 mm x 140 mm (7.5 in x 2.4 in x 5.5 in) [Standard 3500 rack slot] |
| Module Weight | Approx. 0.8 kg (1.8 lbs) |
| Mounting | Slides into a single slot in a 3500 series rack. |
| Power Requirement | Powered by the 3500 rack backplane. |
| Operating Temperature | 0°C to +65°C (+32°F to +149°F) |
| Key Outputs | • Torsional Vibration Level • OK, Alert, and Danger alarms • 4-20 mA output proportional to torsional vibration. |
| Key Features | • Dedicated torsional vibration analysis • Protects against hidden shaft failures • Integrates into the comprehensive 3500 protection framework. |
Note: The dimensions and weight are standard for a module in a 3500 series frame. The specific configuration and measurement ranges are set via the 3500 configuration software.
Application Scenarios
The 3500/60 Torsional Vibration Monitor is deployed in applications where shafts are subjected to significant torque fluctuations and are at risk of torsional fatigue failure. Key application scenarios include:
Reciprocating Compressor Drives: Protecting the shafts of motors or turbines that drive reciprocating compressors, which induce strong torsional excitations.
Marine Propulsion Systems: Monitoring the propeller shafts and drivetrains in large ships, especially those with diesel engines and complex gearboxes.
Electric Motor Drives: Protecting critical motors and their connected equipment (e.g., pumps, fans) that experience rapid load changes or start-up torques.
Multi-Shaft Turbomachinery: Monitoring torsional behavior in complex gear-driven systems like power generation trains and compressor strings.
Test Stands: Used in engine and transmission test cells to monitor torsional vibrations during development and validation.
