Description
The Bently Nevada 133819-01 is a specialized Internal Termination Block designed for use with the 3500/42M Proximitor Seismic Monitor. It serves as the physical interface within the 3500 rack that connects the monitor module to the I/O module, facilitating the secure routing of vibration and seismic sensor signals.

Country of Origin
This component is engineered and manufactured in the United States by Bently Nevada (a Baker Hughes business).
Application Fields
The 133819-01 is used in critical machinery protection systems across various industries:
- Power Generation: Monitoring vibration in large steam and gas turbines.
- Oil & Gas: Interfacing seismic sensors on centrifugal compressors and pumps.
- Petrochemical: Protecting high-speed expanders and cooling tower fans.
- Mining: Monitoring bearings on large crushers and conveyors.
- Water Treatment: Vibration analysis for high-capacity regional water pumps.

Product Usage Instructions
- Safety Precautions: Ensure the 3500 rack is powered down or that the specific slot is bypassed/inhibited before hardware installation to prevent accidental trips.
- Rack Alignment: The 133819-01 is installed from the rear of the 3500 rack. Align the block with the slot corresponding to the 3500/42M monitor module.
- Installation: Press the termination block firmly into the backplane connectors. It should click into place, ensuring a low-resistance electrical path between the front monitor and the rear I/O module.
- I/O Module Attachment: Once the ITB is seated, the 133819-01 serves as the landing pad for the rear I/O module (typically a 128229-01 or similar).
- Verification: Confirm that all gold pins are straight and clean before insertion. Any misalignment can result in “Not OK” channel statuses in the Rack Configuration Software.
Product Technical Description
Technically, the 133819-01 is a bridge component. In the Bently Nevada 3500 architecture, the monitor module (front) and the I/O module (rear) do not plug directly into each other. Instead, they both plug into the Internal Termination Block, which is mounted to the rack’s backplane. This modular design allows for “Hot Swapping” of monitors without disturbing the field wiring connected to the I/O module. The 133819-01 is specifically keyed for the 3500/42M, ensuring that only the correct monitor/IO combination can be energized in that slot.
Q&A (Common Questions)
Q: Can I use the 133819-01 with a 3500/40M monitor? A: No. Each monitor type in the 3500 series has a specific Internal Termination Block. The 133819-01 is specifically designed for the 3500/42M Proximitor Seismic Monitor.
Q: Is this the part where I land my field wires? A: No. The field wires are landed on the Rear I/O Module. The 133819-01 is an internal component that resides inside the rack to connect the internal electronics.
Q: Does this part require any software configuration? A: The hardware itself is passive; however, the 3500 Rack Configuration Software must be set to recognize the 3500/42M monitor in the slot where this block is installed.
Q: What is the most common failure mode for this part? A: Failures are rare but usually involve bent pins or corrosion due to harsh environmental gases if the rack is not properly purged or sealed.
