Product Introduction: 3500/50 133388-02 + 133442-01
The 3500/50 133388-02 and 133442-01 together form a DC Input / Servo Monitor Module and a dedicated Termination Panel for the Bently Nevada 3500 Machinery Protection System. The 3500/50 is a versatile monitoring module designed to accept DC signals from a wide range of sensors and transmitters. The 133442-01 is a custom termination panel that provides a standardized and secure interface for field wiring to connect to the module.
This system is used to monitor various mechanical and process parameters that are transmitted as DC voltage or current signals, converting them into actionable data for alarm and shutdown functions within the 3500 framework.
Technical Parameters
The table below outlines the key parameters for both the module and the termination panel.
| Parameter Category | Specification |
|---|---|
| Part Number Set | 3500/50 133388-02 (Module) + 133442-01 (Termination Panel) |

*Note: The dimensions and weight for the module are standard. The termination panel's physical specs are design-specific. The 133442-01 panel is specifically engineered to work with the 3500/50 module.*
Application Scenarios
The 3500/50 DC Input Module and its termination panel are used to integrate a wide array of non-vibration parameters into the machinery protection system. Key application scenarios include:
Process Parameter Monitoring: Integrating critical process values such as:
Temperature (via RTD or thermocouple transmitters)
Pressure
Flow Rate
Level
Servo Valve Monitoring: Specifically monitoring the LVDT (Linear Variable Differential Transformer) feedback position within electro-hydraulic servo valves on steam turbines and other controlled machinery.
Load & Strain Monitoring: Accepting signals from load cells or strain gauges.
Ancillary Equipment Monitoring: Bringing any critical DC-based signal from auxiliary systems (e.g., lube oil pressure, seal gas differential pressure) into the central 3500 system for alarm and shutdown purposes.
General Purpose Interface: Providing a flexible input channel for custom measurements and legacy sensor systems that output a standard DC signal.
