Description
The Bently Nevada 143488-01 is a Proximitor Monitor module designed for the 3500 series machinery protection system. This four-channel module is engineered to receive and condition input signals from proximity transducers, providing critical vibration and position measurements. By comparing these inputs against user-defined alarm thresholds, the module facilitates reliable machinery protection and diagnostic monitoring for industrial assets such as turbines and centrifugal compressors.
Features
- Four independent monitoring channels for high-density sensor integration.
- Direct compatibility with Bently Nevada proximity probe transducer systems.
- User-configurable alarm and danger setpoints for each channel to ensure precise machine protection.
- Full integration with the 3500 rack backplane for power and communication.
- Buffered transducer signal outputs provided via front-panel coaxial connectors for external diagnostic access.
- Supports a wide range of measurements including shaft vibration, thrust position, eccentricity, and REBAM.
Applications
This monitor is specifically designed for critical rotating machinery protection. It is commonly deployed in power generation and petrochemical facilities to monitor:
- Radial shaft vibration
- Thrust bearing position
- Differential expansion
- Eccentricity and REBAM measurements

Installation Guidelines
- Ensure the 3500 rack is powered down before inserting or removing the module to prevent electrical damage.
- The module should be installed in a clean, dry environment within the specified temperature range.
- Use shielded cabling for all transducer inputs to minimize electromagnetic interference (EMI).
- Ensure the module is fully seated in the rack slot and the front-panel captive screws are tightened to maintain a secure ground connection.
- Verify that the Rack Configuration Software settings match the physical transducer scaling and alarm logic requirements.
FAQ
Is this module compatible with older 3500 series racks?
Yes, the 143488-01 is designed for standard 3500 rack systems. Ensure your rack firmware and configuration software are updated to support the specific module version.
Does this module include the required I/O module?
This listing is for the monitor module itself. Please verify if your specific installation requires a matching I/O module for field wiring termination.
How are the buffered outputs protected?
The front-panel coaxial connectors are short-circuit protected, allowing for safe connection to portable data collectors or oscilloscopes during operation.
