Genuine Bently Nevada 990-04-XX-01-00 165335-01 - Industrial Automation Part

Bently Nevada 990-04-XX-01-00 | 165335-01 Vibration Transmitter – 3500 Series

Description

Bently Nevada 990-04-XX-01-00 – Vibration Transmitter | 3500 Series Platform

Engineering Background
The Bently Nevada 990 Series Vibration Transmitter is a field-proven, loop-powered transducer interface designed for continuous machinery health monitoring in critical rotating equipment applications. Engineered to interface directly with proximity probes (eddy-current sensors), it converts raw displacement or vibration signals into industry-standard 4–20 mA analog outputs compatible with any DCS, PLC, or safety system.

Product Positioning
The 990-04-XX-01-00 (part number 165335-01) is the standard 4-wire, loop-powered variant optimized for integration into Baker Hughes / Bently Nevada 3500 Series rack-based machinery protection systems. It is the preferred choice for procurement engineers specifying turbine, compressor, pump, and motor monitoring solutions in oil & gas, power generation, and petrochemical facilities.

Engineering Advantages

Direct 3500 Rack Integration: Plug-and-play compatibility with Bently Nevada 3500 Series I/O modules eliminates signal conditioning overhead.
Loop-Powered Design: Simplifies field wiring; no separate power supply required at the transmitter head.
Wide Temperature Range: Qualified for both arctic and high-ambient industrial environments.
Hazardous Area Rated: ATEX/IECEx certification supports deployment in Zone 1/2 classified areas.
High Signal Fidelity: Low-noise analog output ensures accurate vibration amplitude and phase data for machinery diagnostics.
Robust Enclosure: IP66/NEMA 4X rating withstands washdown, dust, and corrosive atmospheres.

System Architecture & Signal Flow

The 990-04-XX-01-00 sits between the proximity probe tip and the 3500 rack monitor card. Signal flow: Rotating shaft → Eddy-current proximity probe → 990 Transmitter (signal conditioning + 4–20 mA conversion) → 3500 Monitor Card → DCS/Safety System. The transmitter provides galvanic isolation and linearization, ensuring the downstream control system receives a clean, calibrated analog signal regardless of cable run length or electrical noise environment.

Technical FAQ

Q: Is the 990-04-XX-01-00 compatible with non-Bently Nevada DCS systems?
A: Yes. The 4–20 mA output is universal and connects to any analog input card. The 3500 rack is only required for the full machinery protection feature set.

Q: What proximity probe gap voltage range does this transmitter accept?
A: Typically –2 VDC to –18 VDC (Bently Nevada standard). Confirm with the specific probe datasheet for your installation.

Q: Can I use this transmitter for axial position (thrust) monitoring?
A: Yes, provided the paired proximity probe and extension cable are configured for position measurement and the 3500 monitor card is set accordingly.

Q: Do you provide calibration certificates?
A: Factory calibration data is available for new units. For surplus units, third-party calibration can be arranged upon request.

Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Contact us for current availability.
