Description

Technical Overview

The Bently Nevada 3300 NSv Proximity Probe, model 330908-39-71-05-01-00, is a high-precision, non-contact displacement sensor engineered for continuous monitoring of shaft vibration, axial position, and differential expansion in critical rotating machinery. Designed for integration with the industry-standard 3300 XL 25 mm and 50 mm proximity transducer systems, this probe delivers exceptional signal fidelity and long-term stability under harsh industrial conditions—including extreme temperatures, electromagnetic interference, and mechanical shock.

Manufactured to stringent API 670 (4th Edition) and ISO 10816 compliance standards, the 330908-39-71-05-01-00 probe utilizes advanced eddy-current technology with a robust stainless-steel housing and high-temperature polyimide-insulated cable. Its optimized coil geometry and precision-machined tip ensure repeatable gap measurements within ±0.25% full scale accuracy across its operational range. The probe is calibrated for use with Bently Nevada 3300 NSv monitors and supports both standard and high-temperature applications (up to +175°C at the probe tip), making it ideal for gas turbines, steam turbines, compressors, and large electric motors in power generation, oil & gas, and petrochemical facilities.

Key Features

• API 670–Compliant Performance: Meets or exceeds requirements for machinery protection systems, including linearity, temperature drift, and frequency response specifications.
• High-Temperature Capability: Rated for continuous operation up to +175°C at the probe tip—enabling reliable monitoring in demanding thermal environments.
• Enhanced Mechanical Integrity: Features a hermetically sealed, corrosion-resistant 316 stainless-steel body and abrasion-resistant ceramic tip for extended service life in dirty or abrasive process conditions.
• Plug-and-Play Compatibility: Fully interoperable with 3300 NSv monitors and legacy 3300 XL systems—no recalibration required when replacing existing probes in the same measurement location.
• Traceable Calibration: Supplied with NIST-traceable calibration certificate, ensuring measurement confidence and regulatory audit readiness.
