Component Description
The part number 3500/05-01-02-02-00-01 refers to a specific, fully-configured Main Chassis (or Rack) for the Bently Nevada 3500 Monitoring System.
3500/05: This base number designates the Main Chassis Assembly. This is the physical framework that houses all the monitoring modules, power supplies, and communication interfaces.
-01-02-02-00-01: This extended suffix defines the exact factory configuration of the chassis. It specifies a combination of the following:
Number of Slots: The total number of available slots for modules.
Integrated Hardware: The presence and type of built-in communication interfaces (e.g., a native TCP/IP Ethernet interface for the "Enhanced" framework).
Power Supply Configuration: Whether it is configured for redundant (dual) power supplies.
Specific Kits: Inclusion of specific mounting kits, terminal blocks, or other hardware.
In essence, this part number does not represent a single functional module but the entire "backbone" or "housing" of the protection system. It is a pre-configured assembly that defines the system's capacity and core capabilities, ensuring all components are properly integrated and powered.
Key Parameters
The following table outlines the key parameters for this 3500 Main Chassis configuration.
| Parameter | Specification |
|---|---|
| System | Bently Nevada 3500 |
| Primary Function | System Backbone; Houses and Interconnects all Monitoring Modules & Power Supplies |
| Framework Type | Typically indicates a 3500 Enhanced Framework with integrated TCP/IP interface. |
| Total Slots | Configuration-specific (e.g., 14 slots). A certain number are dedicated to power supplies and the framework module. |
| Module Slots | Configuration-specific number of slots available for monitor, relay, and TDI modules (e.g., 11 slots). |
| Power Supply Slots | Typically 2 or 3 slots, often configured for redundant (dual) power supply operation. |
| Integrated Communication | Includes a built-in TCP/IP Ethernet interface for connectivity to monitoring software (e.g., System 1™) and DCS/PLC systems. |
| Backplane | Provides power, communication, and synchronization for all installed modules. |
| Mounting | Designed for 19-inch rack mounting or panel mounting. |
| Dimensions (H x W x D) | Approx. 425 mm (16.75 in) (H) x 482 mm (19 in) (W) x 260 mm (10.25 in) (D) Note: Height may vary slightly with slot count. |
| Weight (Empty) | Approx. 11 kg (24 lbs) |
Application Scenarios
The 3500/05 Main Chassis is the foundation for any Bently Nevada 3500 system installation. Its application is universal, but its specific configuration determines its suitability for different scales of machinery protection.
Complete Turbine or Compressor Protection Suite:
Application: Gas Turbines, Steam Turbines, Centrifugal Compressors.
Function: This specific configuration, likely with an enhanced framework and multiple slots, is designed to house a full suite of monitors (vibration, position, speed, temperature) and relays required to fully protect a critical machine train, providing a centralized, integrated protection system.
High-Availability Systems in Power Generation:
Application: Critical units in power plants.
Function: The chassis is configured to support redundant power supplies and multiple communication paths. This ensures maximum system uptime and reliability, as a failure in one power supply or communication card will not compromise the entire protection system.
Centralized Monitoring for Multiple Machine Trains:
Application: Large process units in refineries or petrochemical plants.
Function: A larger chassis configuration can be used to consolidate the protection of several critical machines into a single rack, simplifying wiring, maintenance, and data management.
Foundation for Any 3500 System:
Application: Any installation requiring Bently Nevada 3500 monitoring.
Function: It is the mandatory physical platform that provides power, data communication, and synchronization for all monitoring modules. Without the chassis, the individual modules cannot operate as a coordinated system.
