Description
The BENTLY 3500/25-01-03-00 is a specific variant of the Bently Nevada 3500 Enhanced Keyphasor Module designed for use within the Bently Nevada 3500 machinery protection system in industrial applications. Here’s a breakdown of what we can glean from publicly available resources:
Function:
- Provides Keyphasor signals to the monitor modules in a 3500 system. A Keyphasor signal is a critical timing pulse generated once per revolution from a shaft or gear on a rotating machine. This precise measurement is crucial for various machinery protection functions like:
- Machine speed monitoring
- Shaft relative position monitoring in multi-shaft machines
- Order tracking analysis for vibration analysis
Key Characteristics:
- Offers two independent Keyphasor signal channels.
- Half-height module for efficient use of space within a Bently Nevada 3500 rack.
- Rugged construction for harsh industrial environments (dust, moisture, etc.).
- Internal Barrier I/O with Internal Terminations: This likely indicates that the module has built-in electrical isolation features to prevent interference between input signals and the internal circuitry of the module and the 3500 system. Internal terminations are resistors placed at the end of signal cables to minimize signal reflections and ensure proper signal integrity.
- Not Agency Approved: The final digits “00” in the suffix suggest that this variant doesn’t have specific approvals from regulatory agencies for use in hazardous locations (explosion zones).
Finding Detailed Specifications and User Manuals:
Obtaining a user manual specifically for the 3500/25-01-03-00 variant might be challenging. Here’s how to find the closest resources:
-
Bently Nevada Website: Search for “Bently Nevada 3500/25-01-03-00” under “Product Literature” or “Downloads” sections on the Bently Nevada website (https://www.bakerhughes.com/bently-nevada). If a dedicated user manual isn’t available, try searching for “Bently Nevada 3500/25” or the general “3500 Keyphasor Module” manuals. These will provide details on the core functionalities, configuration aspects, and compatibility with other 3500 system modules, which will likely be similar for the 3500/25-01-03-00 variant.
-
General 3500/25 User Manuals: Focus on user manuals related to the Bently Nevada 3500 system mentioning the 3500/25 Keyphasor Module, especially those that don’t specify a suffix after “-01-03-“. These documents will be essential for understanding:
-
- Compatibility with other Bently Nevada 3500 system modules for data acquisition.
- Wiring and installation instructions for connecting the module to the system and machinery.
- Configuration details (if applicable) – some variants might require specific settings within the 3500 system software.
-
Datasheets: Look for datasheets specifically mentioning the “3500/25 Keyphasor Module with Internal Barrier I/O and Internal Terminations”. These might be available on Bently Nevada’s website or through authorized distributors. Datasheets are concise documents that often summarize technical specifications without elaborate descriptions.
Additional Notes:
- The Bently Nevada 3500 system software might be necessary for configuring the 3500/25-01-03-00 module. Refer to the general user manuals (as suggested above) for details on the software and its functionalities.
- For proper installation, configuration, and operation of the 3500/25-01-03-00 module within your specific system, consider consulting a qualified professional familiar with Bently Nevada systems. They can ensure it’s set up correctly to provide the necessary Keyphasor signals for your machine protection analysis needs and ensure it complies with any relevant safety regulations for your application (especially if hazardous locations are involved).
Important Consideration for Hazardous Locations:
The “00” suffix suggests this module lacks agency approvals for hazardous locations. If your application involves hazardous locations (explosion zones), using a Bently Nevada 3500/25 variant with the necessary certifications is crucial for safety compliance. Consult with Bently Nevada or a qualified professional to ensure you select the appropriate module for your hazardous environment.
