Application Solutions

Turbomachinery Condition Monitoring: The 3500/22-01-00 TDI module excels in steam turbine, gas turbine, and compressor monitoring applications where detailed vibration signatures are essential for early fault detection. Deploy alongside Bently Nevada 3500/42M Proximitor Seismic Monitors and 3500/40M Proximitor Monitors to capture shaft displacement, casing vibration, and bearing temperature data simultaneously.

Predictive Maintenance Programs: Integrate with System 1 Evolution software to establish baseline machinery signatures, track degradation trends, and trigger automated alerts before catastrophic failures occur. The TDI module works in concert with Bently Nevada 3500/50 Tachometer modules to correlate speed-dependent vibration phenomena with operational parameters.

Power Generation Asset Protection: Critical for generator bearing monitoring, thrust position tracking, and rotor eccentricity detection in combined-cycle plants and cogeneration facilities. Pair with 3500/46M Hydro Monitors for comprehensive turbine-generator protection systems that capture both vibration and hydraulic pressure transients.

Oil & Gas Processing Facilities: Essential for compressor train monitoring, pipeline pump surveillance, and offshore platform equipment protection where remote diagnostics capabilities reduce maintenance costs and improve safety. The Ethernet interface enables integration with plant-wide SCADA systems and remote operations centers.

System Architecture & Integration

The 3500/22-01-00 TDI module installs in any available slot within Bently Nevada 3500/05 system racks and communicates with all installed monitor modules via the internal rack backplane. Unlike standalone 3500/20 Rack Interface Modules, the TDI provides enhanced data acquisition capabilities specifically designed for transient event capture and waveform analysis.

For complete machinery protection systems, combine the TDI module with Bently Nevada 3500/92 Communication Gateway modules to enable simultaneous System 1 integration and Modbus/Ethernet connectivity to DCS platforms. The dual-interface architecture ensures continuous data flow to both condition monitoring and process control systems.

Configuration & Deployment

Configuration of the 3500/22-01-00 requires 3500 Rack Configuration Software and System 1 Evolution version 6.0 or higher. The module supports both static (fixed IP) and DHCP network addressing, with configurable data transmission rates to optimize network bandwidth utilization. Waveform capture triggers can be configured based on alarm conditions from any monitor module in the rack, including 3500/65 Temperature Monitors and 3500/53 Overspeed Detection modules.

Common Questions & Answers

Q: What is the difference between the 3500/22 TDI and the 3500/20 RIM?
A: The 3500/20 Rack Interface Module provides basic configuration and diagnostic access to the 3500 rack, while the 3500/22 TDI adds high-speed transient data capture capabilities and System 1 integration. The TDI module includes all RIM functionality plus waveform acquisition, making it the preferred choice for predictive maintenance applications.

Q: Can I use multiple TDI modules in a single 3500 rack?
A: Yes, you can install up to two TDI modules in a single 3500 rack for redundancy or to support multiple System 1 servers. Each TDI module requires a unique IP address and can independently capture and transmit waveform data from all monitor modules in the rack.

Q: What network infrastructure is required for TDI deployment?
A: The 3500/22-01-00 requires standard 10/100 Mbps Ethernet connectivity with TCP/IP protocol support. For optimal performance, deploy on a dedicated monitoring network or VLAN with minimum 100 Mbps switched infrastructure. Typical bandwidth utilization ranges from 1-5 Mbps depending on waveform capture frequency and buffer size settings.

Q: Is the TDI module compatible with legacy System 1 versions?
A: The 3500/22-01-00 requires System 1 Evolution version 6.0 or higher. For legacy TDXnet-based systems, consider the 3500/22M TDI module or 2155/00 TDXnet mainframe for backward compatibility with older monitoring infrastructure.

Q: How do I configure waveform capture triggers?
A: Waveform captures can be triggered by alarm conditions from any monitor module, manual requests from System 1 software, or scheduled periodic snapshots. Use the 3500 Rack Configuration Software to define trigger sources, pre-trigger buffer depth (typically 25-50% of total capture), and post-trigger duration based on your diagnostic requirements.

Q: What happens to waveform data during network outages?
A: The TDI module’s 16 MB internal buffer stores captured waveforms during network interruptions. Once connectivity is restored, buffered data automatically transmits to System 1 in chronological order. For extended outages exceeding buffer capacity, the oldest waveforms are overwritten using a first-in-first-out (FIFO) algorithm.
