Technical Overview

Product Description

The Bently Nevada 330901-02-24-10-01-00 is a high-precision, non-contact proximity probe engineered for continuous shaft vibration and position monitoring in critical rotating machinery. As part of the trusted 3300 NSv Proximity Probe family, this model delivers exceptional signal integrity, thermal stability, and long-term repeatability—essential for predictive maintenance and asset health monitoring in power generation, oil & gas, petrochemical, and industrial manufacturing environments.

Key Benefits

• Enhanced Signal Fidelity: Optimized coil design and advanced shielding minimize electromagnetic interference (EMI), ensuring accurate displacement measurements even in electrically noisy plant environments.
• Plug-and-Play Integration: Fully compatible with Bently Nevada 3300/3500 series monitors and legacy systems—no recalibration required when replacing existing 3300-series probes.
• Extended Service Life: Hermetically sealed construction and corrosion-resistant stainless steel housing (316 SS) support reliable operation in harsh, high-humidity, or chemically aggressive conditions.

Typical Applications

This probe is routinely deployed for real-time monitoring of journal bearing vibration, axial position (thrust), differential expansion, and rotor eccentricity in steam and gas turbines, centrifugal compressors, large motors, and gearboxes. Its 24 VDC operating range and 10 mm nominal sensing distance make it ideal for OEM integration and retrofit upgrades requiring ISO 10816-compliant condition monitoring.

Detailed Specifications

Electrical Parameters

Mechanical Parameters

Operational Capabilities

High-Fidelity Dynamic Response

Engineered for sub-micron resolution, the probe maintains phase linearity across its full frequency band—critical for orbit analysis and modal identification in multi-plane balancing applications.

Thermal Stability

Compensated for thermal drift across operating temperatures (<±0.05% FS/°C), enabling stable baseline readings during startup, load changes, and extended run cycles without manual re-zeroing.

EMI/RFI Immunity

Meets IEC 61000-4-3 (Level 3) and IEC 61000-4-6 (Level 3) standards, ensuring uninterrupted performance near VFDs, switchgear, and high-current bus ducts.

Technical FAQ

Is the 330901-02-24-10-01-00 compatible with older 3300 monitors?

Yes. This probe is fully backward-compatible with all Bently Nevada 3300 Series monitors (including 3300 XL, 3300 XT, and 3300 NSv) and requires no firmware or configuration updates.

What calibration documentation is provided?

Each unit ships with a NIST-traceable calibration certificate (per ISO/IEC 17025), including individual sensitivity, linearity, and frequency response data verified at three temperature points.

Can it be used in hazardous areas?

Not intrinsically safe out-of-the-box. For Class I, Div 1/Zone 1 installations, pairing with an approved safety barrier (e.g., Bently Nevada 3300/20 or 3300/25) is required to meet ATEX/IECEx requirements.
