Bently Nevada 990-05-XX-01-00 165335-01 – Dual-Channel Vibration Transmitter | 3500 Series Platform
Engineering Background: The Bently Nevada 3500 Series is the industry benchmark for continuous online machinery protection in rotating equipment applications. Deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide, the platform delivers real-time vibration, position, and dynamic measurement data to safeguard critical rotating assets.
Product Positioning: The 990-05-XX-01-00 (P/N 165335-01) is a dedicated vibration transmitter module within the 3500 rack-based monitoring system. It conditions raw transducer signals—typically from proximity probes or accelerometers—into standardized 4–20 mA or voltage outputs compatible with DCS, SCADA, and safety instrumented systems (SIS). This module is essential for engineers requiring certified, rack-integrated vibration monitoring without compromise on signal fidelity or system uptime.

- Configurable via System 1 / Rack Configuration Software: Full parameter configuration without hardware changes—alarm setpoints, measurement modes, and output scaling adjustable in software.
- Dual-Channel Design: Monitors two independent measurement points per module, maximizing rack density and reducing per-channel cost.
- High Signal Fidelity: Precision analog front-end with low noise floor, suitable for early fault detection in low-amplitude vibration regimes.
- Hot-Swap Capable: Designed for removal and insertion under power within the 3500 rack, minimizing maintenance downtime.
System Architecture & Signal Flow
The 990-05-XX-01-00 module installs into any standard 3500 rack slot. Transducer signals enter via the I/O module terminal block on the rear of the rack. The transmitter conditions the signal, applies configured filtering and scaling, and outputs a 4–20 mA loop signal to the plant DCS or SIS. Simultaneously, the module communicates measurement data over the rack backplane to the 3500/20 Communication Gateway for integration with historian and SCADA systems. Alarm relay outputs are routed through the rack’s relay output module for hardwired trip logic.

Technical FAQ
Q: Is the 990-05-XX-01-00 compatible with all 3500 rack configurations?
A: Yes. The module is compatible with standard 3500 racks (3500/05, 3500/15, 3500/22M) and requires a corresponding I/O module for rear-panel signal termination.
Q: What transducer types are supported?
A: The module supports Bently Nevada 3300 XL and 7200 Series proximity probes, as well as compatible third-party eddy-current probes meeting the same sensitivity specification (typically 7.87 V/mm or 200 mV/mil).
Q: Can this module be used as a direct replacement for an existing 990-05 variant?
A: The 990-05-XX-01-00 designation covers the standard configuration. Confirm your existing module’s full part number and firmware revision with our technical team before substitution in a live system.
Q: Is SIL 2 certification available at the module level?
A: SIL 2 is achieved at the system level within a validated 3500 rack configuration. Contact Konmask for documentation support for your SIL assessment.
Q: What is the typical lead time?
A: In-stock units ship within 2–3 business days. For out-of-stock items, typical sourcing lead time is 2–4 weeks. Contact us for current availability.
