Description

Technical Overview

The Bently Nevada 330703-00-100-10-11-CN is a high-precision 3300 XL 11 mm proximity probe engineered for mission-critical machinery monitoring in demanding industrial environments. As part of the industry-leading 3300 XL series, this probe delivers exceptional linearity, temperature stability, and electromagnetic interference (EMI) immunity—ensuring reliable shaft displacement, vibration, and position measurements across turbines, compressors, motors, and other rotating equipment. Its robust stainless-steel construction and hermetically sealed design meet stringent IP67 and NEMA 4X requirements, enabling continuous operation in high-humidity, dusty, or chemically aggressive settings common in power generation, oil & gas, and heavy manufacturing facilities.

Designed for seamless integration with Bently Nevada 3300 XL monitoring systems—including the 3300/16, 3300/20, and 3500 platforms—the 330703-00-100-10-11-CN features optimized sensitivity (8.0 V/mm), a linear range of ±2.0 mm, and a calibrated gap voltage of –10.0 VDC at the nominal air gap. Its low-noise, high-fidelity signal output supports real-time diagnostics, predictive maintenance strategies, and compliance with ISO 10816 and API 670 standards. With a proven track record of long-term repeatability and minimal drift over time, this probe significantly reduces unplanned downtime and enhances asset lifecycle management for OEMs and end-user maintenance teams alike.

Key Features

• Precision 11 mm Sensing Tip: Optimized for accurate, repeatable non-contact measurement of shaft vibration and axial position within tight mechanical clearances.
• Enhanced Environmental Resilience: IP67-rated housing with corrosion-resistant 316 stainless-steel body and PTFE-insulated coaxial cable rated for continuous operation up to 125°C.
• Plug-and-Play Compatibility: Fully compliant with Bently Nevada 3300 XL system architecture—no field calibration required when paired with matching 3300 XL extension cables and transducers.
• EMI/RFI Immunity: Engineered with proprietary shielding and differential signaling to maintain signal integrity in high-noise electrical environments.
• Long-Term Stability: Factory-calibrated and traceable to NIST standards, with less than 0.5% full-scale drift over 5 years under normal operating conditions.
