Product Overview
The BENTLY 330100-90-00 is a high-precision eddy-current proximity sensor system designed for industrial machinery health monitoring, forming a critical component of Bently Nevada’s 3300 XL series. This system converts mechanical vibration and displacement signals into standardized electrical outputs (e.g., -1 to -17 Vdc), enabling real-time tracking of shaft dynamics in rotating equipment like turbines, compressors, and pumps. Its core function lies in detecting radial vibration, axial displacement, keyphasor (phase reference), and speed, providing essential data for predictive maintenance to prevent unplanned downtime and catastrophic failures.
Engineered for harsh industrial environments, the BENTLY 330100-90-00 complies with API 670 Standard (4th Edition) for machinery protection systems. Its rugged stainless steel housing (IP66/NEMA 4X-rated) withstands extreme temperatures (-40°C to +85°C), dust, moisture, and electromagnetic interference (EMI/RFI). The module’s plug-and-play design ensures full interchangeability of probes, cables, and preamplifiers without recalibration, significantly reducing installation complexity and maintenance costs. As a cornerstone of automation frameworks, it seamlessly integrates with DCS, PLC, or SCADA systems via 4–20 mA or voltage signals, bridging sensor data to control units like Bently’s 3500 series monitors for actionable insights.

Key Features and Benefits
Precision and Interchangeability: The BENTLY 330100-90-00 delivers ±1% full-scale accuracy across its 2mm linear range, critical for detecting micro-level machinery faults. Probes, cables, and preamplifiers are fully interchangeable without recalibration, simplifying spares management and reducing commissioning time. Its auto-temperature compensation maintains stability from subzero cold starts to turbine-grade heat.
Robust Design for Critical Environments: Encased in corrosion-resistant stainless steel, the module resists oil, chemicals, and high-pressure washdowns. EMI/RFI shielding ensures signal integrity near high-voltage equipment, while the IP66 rating guarantees reliability in offshore platforms, refineries, and desert installations.
Ease of Integration: Dual mounting (panel or rail) and compatibility with legacy 3300 series hardware streamline retrofits. Loop-powered operation eliminates external PSUs, and self-diagnostics flag sensor faults or cable degradation. Output scaling can be customized for specific machinery thresholds via DIP switches.
Regulatory Compliance: Meets API 670, ATEX, and IECEx standards for hazardous areas, with intrinsic safety options. Calibration traceability via TK-3E kits ensures audit-ready documentation.
Application Areas
The BENTLY 330100-90-00 excels in high-stakes industrial monitoring:
- Power Generation: Tracks steam/gas turbine vibrations and rotor imbalances to prevent blade failures. Monitors hydroelectric generator shafts for oscillation anomalies.
- Oil & Gas: Safeguards centrifugal compressors in pipelines and refineries by detecting bearing wear or misalignment. Its high-temperature tolerance suits gas turbine exhaust zones.
- Heavy Manufacturing: Ensures precision in paper mill rollers, cement kiln drives, and steel plant gearboxes through real-time vibration analysis.
- Marine & Aerospace: Monitors propulsion engines and test-rig dynamics via 10 kHz frequency response for high-RPM validation.

Installation and Maintenance
Installation Preparation: Verify power supply stability (-17.5Vdc min.) and use shielded triple-core cables (≤305m). Mount probes perpendicular to targets with 1.5–2mm gap for steel shafts. Match probe-cable length (e.g., 9m probe + 9m preamplifier) to avoid signal drift.
Maintenance Recommendations: Bi-annually check probe resistance (target: 7–8Ω for 1m probes) and inspect connectors for oil contamination. Perform full-scale calibration with TK-3E to validate linearity. Replace cracked probe insulation immediately to prevent short circuits.
Product Assurance
The BENTLY 330100-90-00 includes a 12-month warranty against manufacturing defects. Global technical support covers installation, troubleshooting, and calibration training. Units undergo factory testing per ISO 9001, CE, and UL standards, with lifetime firmware updates via authorized partners.
