Product Overview
The Bently Nevada 3500/40-01-01 (176449-01) is a 4-channel Proximitor Monitor designed for high-precision vibration and position monitoring of rotating machinery. As a core component of the 3500 Series Machinery Protection System, this module processes signals from Bently Nevada proximity sensors (e.g., 3300 XL series) to provide real-time measurements of critical parameters like radial vibration, axial displacement, and differential expansion. Engineered for compliance with API 670 standards, the 3500/40-01-01 ensures reliable operation in oil & gas, power generation, and industrial automation environments where machinery health is mission-critical.
Featuring epoxy-sealed construction and galvanic isolation, the module withstands harsh conditions (e.g., EMI, high vibration) while delivering ±0.33% full-scale accuracy for vibration measurements. Its programmable alarm setpoints (via 3500 Rack Configuration Software) enable automatic actuation of shutdowns or alarms through connected relay modules (e.g., 3500/34), ensuring fail-safe protection. The hot-swappable design minimizes downtime during maintenance, while front-panel LEDs provide instant status feedback (green for normal operation, red for faults).
In automation architectures, the 3500/40-01-01 acts as a vital interface between sensors and control systems, converting raw sensor data into actionable insights. By integrating with Bently Nevada’s System 1 software, it supports predictive maintenance strategies, reducing unplanned outages and extending equipment lifespan.

Key Features and Advantages
Multi-Parameter Monitoring: The 3500/40-01-01 supports 8 independent measurement modes (e.g., REBAM® for rolling-element bearing analysis), allowing simultaneous monitoring of vibration, position, and expansion. This versatility eliminates the need for multiple dedicated modules, reducing system complexity and cost.
High Accuracy and Stability: With ±0.33% full-scale accuracy and 10,000-hour MTBF, the module ensures precise long-term performance. Its adaptive filtering reduces noise interference, enhancing signal integrity in high-vibration environments.
Programmable Logic Flexibility: The 3500 Rack Configuration Software enables user-defined alarm logic (e.g., 2-out-of-3 voting for critical channels) and configurable deadbands. Each channel can be assigned normally energized (NE) or normally de-energized (NDE) relay outputs, aligning with diverse control requirements.
Robust Environmental Resilience: The IP65-rated enclosure and arc-suppression circuitry protect against moisture, dust, and electrical transients. The module’s 10,000-cycle contact life reduces maintenance costs compared to mechanical relays.
Seamless Integration: Compatible with 3500/92 Communication Gateway, the 3500/40-01-01 supports Modbus RTU/TCP connectivity to PLCs and SCADA systems. It also interfaces with Bently Nevada’s 3500/22M Transient Data Interface for high-speed waveform analysis.
Application Areas
The Bently Nevada 3500/40-01-01 (176449-01) excels in applications requiring continuous machinery health monitoring:
- Oil & Gas: Monitoring compressor turbine shaft vibration and axial thrust in offshore platforms and refineries.
- Power Generation: Detecting rotor eccentricity in steam turbines and generator misalignment in power plants.
- Industrial Manufacturing: Ensuring precision in extruders, centrifuges, and ball mills by measuring radial vibration thresholds.
- Aerospace: Validating engine balance during testing by analyzing differential expansion data.
- Nuclear Energy: Providing real-time displacement measurements for reactor coolant pumps, critical for safety compliance.
By converting sensor data into actionable insights, the 3500/40-01-01 empowers predictive maintenance strategies, reducing repair costs by up to 30% in case studies.
