Product Overview
The BENTLY 330104-00-05-10-02-CN is an 8mm eddy-current proximity probe from Bently Nevada’s 3300 XL series, engineered for high-precision vibration and displacement monitoring in critical rotating machinery. This probe operates on electromagnetic induction principles, generating oscillating fields that interact with conductive surfaces to convert mechanical gap changes into standardized voltage signals (-1 to -17 Vdc). Designed for harsh industrial environments, it features a corrosion-resistant stainless steel housing (IP67/NEMA 4X-rated) that withstands extreme temperatures (-40°C to +85°C ambient; probe tip tolerates up to +177°C), moisture, chemicals, and electromagnetic interference. As a core component of predictive maintenance systems, the BENTLY 330104-00-05-10-02-CN seamlessly integrates with monitoring frameworks like the 3500 series, enabling real-time detection of radial vibration, axial displacement, and keyphasor signals to prevent catastrophic failures in turbines, compressors, and pumps. Its plug-and-play design ensures full interchangeability with 3300 XL extension cables and proximitor modules without recalibration, significantly reducing downtime and maintenance costs while complying with API 670 4th Edition standards for machinery protection.

Key Features and Benefits
Precision and Interchangeability: The BENTLY 330104-00-05-10-02-CN delivers ±1% accuracy across its 2mm linear range, critical for detecting micro-scale faults like bearing wear or shaft misalignment. Its fully interchangeable design with 3300 XL series probes, cables, and proximitors eliminates bench calibration, slashing replacement time by 50%. The auto-temperature compensation maintains stability from subzero cold starts to turbine exhaust zones.
Robust Industrial Design: Encased in 316L stainless steel with ClickLoc® connectors, the probe resists high-pressure washdowns, oil immersion, and EMI/RFI interference. The IP67 rating ensures reliability in offshore rigs, refineries, and humid environments. Optional FluidLoc cables prevent fluid ingress, enhancing longevity in submerged applications.
Ease of Integration: Finger-tightened connectors and M10×1 threading simplify installation in confined spaces. Integrated locknuts prevent loosening under vibration, while compatibility with legacy 3300 series hardware streamlines retrofits. Real-time diagnostics via 3500/42M monitors enable early alerts for imbalance or rubbing conditions.
Application Areas
The BENTLY 330104-00-05-10-02-CN excels in high-stakes sectors:
- Power Generation: Monitors steam/gas turbine shaft vibrations and rotor imbalances to prevent blade failures. Its low-frequency response (0.5 Hz) detects hydroelectric generator oscillations during load shifts.
- Oil & Gas: Safeguards centrifugal compressors in pipelines by identifying bearing degradation; high-temperature tolerance (177°C) suits gas turbine exhaust zones.
- Heavy Manufacturing: Tracks gearbox vibrations in steel mill rollers and paper machine drives, enabling maintenance during production pauses.
- Aerospace Testing: Validates engine rotor dynamics in test rigs via 10 kHz frequency response for high-RPM validation.

Installation and Maintenance
Installation Preparation: Mount the probe perpendicular to the target (e.g., steel shaft) with a 1.5–2mm gap. Use shielded triaxial cables (≤305m) to minimize EMI, and match probe-cable lengths (e.g., 5m probe with 5m extension) to prevent signal drift. Verify power stability (-17.5Vdc min.) for connected 330180-90-00 proximitors.
Maintenance Recommendations: Bi-annually inspect probe resistance (target: 7–8Ω) using a multimeter. Clean oil/grease with isopropyl alcohol, and validate linearity via TK-3E calibration tools. Replace probes if output deviation exceeds ±5% or insulation shows cracks.
Product Assurance
The BENTLY 330104-00-05-10-02-CN includes a 12-month warranty against manufacturing defects. Global technical support covers installation guidance, field diagnostics, and calibration training. Units undergo ISO 9001-certified testing, with lifetime firmware updates for compatible monitoring systems via authorized partners.
