Technical Overview

Product Description

The Bently Nevada 330180-50-CN is a high-precision, non-contact proximity probe engineered for continuous vibration and position monitoring in critical rotating machinery. As part of the trusted 3300 NSv Proximity Probe family, this model delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—essential for reliable operation in harsh industrial environments such as power generation, oil & gas, and heavy manufacturing. Designed for seamless integration with Bently Nevada 3300 Series monitoring systems, the 330180-50-CN features a rugged stainless-steel housing, hermetically sealed construction, and optimized tip geometry for accurate gap measurement across its calibrated range.

Key Benefits

• Enhanced Reliability: Built to meet IEC 61508 SIL 2 requirements for functional safety-critical applications.
• Plug-and-Play Compatibility: Fully compatible with 3300 XL and 3300 NSv extension cables and前置 amplifiers—no recalibration required.
• Extended Service Life: Gold-plated connectors and corrosion-resistant materials ensure long-term performance in high-humidity, high-vibration, or chemically aggressive settings.

Typical Applications

This probe is widely deployed for shaft relative vibration, axial position, differential expansion, and keyphasor timing measurements on steam/gas turbines, centrifugal compressors, large motors, and gearboxes. Its 50 mm sensing range and ±1% linearity make it ideal for medium-to-large diameter rotors where precise displacement tracking is mission-critical for predictive maintenance and asset integrity programs.

Detailed Specifications

Operational Capabilities

High-Fidelity Signal Integrity

Engineered with advanced eddy current technology and low-noise internal circuitry, the 330180-50-CN maintains signal fidelity up to 10 kHz bandwidth—enabling accurate capture of high-frequency vibration events such as blade pass, gear mesh, and bearing fault signatures.

Robust Environmental Resilience

IP67-rated enclosure and MIL-DTL-38999-style connector ensure reliable operation under extreme mechanical shock (50 g), continuous vibration (20 g RMS), and exposure to hydrocarbons, steam, and salt-laden atmospheres—common in offshore platforms and combined-cycle plants.

Calibration Traceability & Compliance

Each unit ships with NIST-traceable calibration certificate and conforms to API RP 670 (4th ed.) and ISO 10816 standards for machinery protection system sensors.

Technical FAQ

Can the 330180-50-CN be used with legacy 3300 series monitors?

Yes—the 330180-50-CN is backward-compatible with all 3300 series monitors (including 3300/16, 3300/20, and 3300 XL systems) when paired with appropriate 3300 NSv extension cables and前置 amplifiers. No firmware updates or configuration changes are required.

What is the recommended mounting torque for the probe body?

The stainless-steel probe body should be torqued to 20–25 N·m (15–18 lbf·ft) using a calibrated torque wrench. Over-torquing may deform the tip assembly and compromise calibration accuracy.

Is field recalibration possible?

No—this probe is factory-calibrated and sealed. Recalibration must be performed by an authorized Bently Nevada service center using certified reference standards and environmental chambers to maintain compliance with API and ISO specifications.
