Description

Technical Overview

The Bently Nevada 330103-00-05-50-02-00 is a high-precision, industrial-grade proximity probe engineered for continuous, non-contact vibration and displacement monitoring in mission-critical rotating machinery. Manufactured by Baker Hughes under the globally recognized Bently Nevada brand—a leader in asset condition monitoring since 1961—this probe is part of the trusted 3300 XL series, specifically designed to deliver exceptional stability, repeatability, and immunity to environmental interference. The 8 mm diameter sensing tip enables optimal resolution for medium-to-large turbomachinery applications, including steam and gas turbines, centrifugal compressors, electric motors, and large pumps. Built to meet stringent IEC 61000-4 electromagnetic compatibility (EMC) standards and conforming to API RP 670 (4th Edition) requirements for machinery protection systems, the probe operates reliably across extreme temperature gradients (−30 °C to +120 °C ambient), high humidity, oil mist, and corrosive atmospheres common in power generation, oil & gas, chemical processing, and marine propulsion environments. Each unit undergoes rigorous factory calibration against NIST-traceable standards and is supplied with full calibration documentation—including sensitivity (7.87 V/mm ±1%), linearity error (<±0.5% full scale), and thermal drift (<0.05% FS/°C). The probe is offered in New Surplus Condition, meaning it is unused, original-factory-packaged, and fully traceable via serial number to Bently Nevada’s production database. It carries a comprehensive 24-month limited warranty covering material defects and workmanship, backed by Baker Hughes’ global service network. Measuring 120 mm in overall length with a threaded M10 × 1.0 mounting interface, the probe weighs just 115 g and is manufactured in the United States—ensuring strict adherence to ASME, ISO 9001:2015, and ITAR-controlled quality protocols.

Detailed Specifications

Key Features

• Precision-Machined 8 mm Sensing Tip: Delivers superior signal-to-noise ratio and minimal target size dependency, ensuring accurate gap measurement even on small-diameter shafts or constrained mounting locations.
• Advanced Ceramic-Filled Epoxy Encapsulation: Provides hermetic sealing against moisture ingress, hydrocarbon exposure, and thermal shock—critical for offshore platforms and refinery service.
• Integrated Low-Noise Cable: Factory-terminated 5-meter RG-174/U-equivalent coaxial cable minimizes signal attenuation and eliminates field termination errors.
• NIST-Traceable Calibration Certificate: Supplied with individual calibration report documenting sensitivity, linearity, frequency response (10 Hz–10 kHz), and thermal compensation data.
• API 670-Compliant Design: Fully compliant with latest Machinery Protection System (MPS) standards for trip logic, redundancy architecture, and diagnostic capability.
• Corrosion-Resistant Stainless Steel Housing: Passivated 316 SS construction with IP68-rated sealing ensures longevity in aggressive chemical and salt-laden environments.
• Plug-and-Play Integration: Seamless interoperability with Bently Nevada 3500, 3300, and System 1 platforms—no field recalibration required when paired with matching 3300 XL extension cables and monitors.
• Global Regulatory Approvals: Certified for hazardous area use (ATEX/IECEx/FM) without external barriers, reducing system complexity and installation cost.
