Description

Technical Overview

The Bently Nevada 330101-36-80-10-02-00 is a high-precision, industrial-grade proximity probe engineered for continuous, non-contact vibration and position monitoring in critical rotating machinery applications. Manufactured by Baker Hughes under the globally recognized Bently Nevada brand—a leader in asset protection and condition monitoring since 1961—this probe is part of the trusted 3300 XL series, specifically designed to deliver exceptional signal fidelity, thermal stability, and long-term reliability in demanding environments. As a 8 mm diameter eddy-current proximity sensor, it operates on the principle of electromagnetic induction to measure dynamic displacement (vibration), static position (gap), and axial thrust with micron-level resolution. The probe is factory-calibrated to the 3300 XL extension cable and monitor system, ensuring seamless integration and traceable metrological performance compliant with API 670 (4th Edition) and ISO 10816 standards. Each unit undergoes rigorous environmental stress screening—including temperature cycling, shock, and vibration testing—to guarantee operational integrity across ambient temperatures from –30 °C to +120 °C. Supplied new in original factory packaging, this probe is offered in “New — Factory Fresh” condition, backed by a comprehensive 24-month limited warranty covering material defects and workmanship. Its compact, robust stainless steel housing (316 SS) provides superior corrosion resistance, making it ideal for oil & gas, power generation, petrochemical, and marine propulsion systems where uptime, safety, and regulatory compliance are non-negotiable.

Detailed Specifications

Key Features

• Factory-Calibrated System Integration: Pre-matched to 3300 XL extension cables and monitors for zero calibration drift and guaranteed linearity across full linear range.
• High-Temperature Stability: Advanced coil design and thermal compensation ensure consistent sensitivity and null point stability up to +120 °C probe tip temperature.
• Corrosion-Resistant Construction: 316 stainless steel housing and PTFE cable jacket resist aggressive chemical exposure, salt spray, and high-humidity conditions.
• Low-Noise, Wide-Bandwidth Output: Delivers clean, low-phase-shift signals from DC to 10 kHz—ideal for detecting subsynchronous whirl, rubs, and bearing faults.
• API 670-Compliant Performance: Meets stringent requirements for gap voltage tolerance, sensitivity accuracy, and repeatability essential for machinery protection systems (MPS).
• Quick-Install Mechanical Design: Integral 10-32 UNF thread enables secure mounting in standard probe housings; compact profile minimizes installation footprint in space-constrained locations.
• Traceable Metrology: Each probe includes NIST-traceable calibration certificate with serial-number-matched test data including linearity error, hysteresis, and temperature coefficients.
• Global Support & Lifecycle Management: Backed by Baker Hughes’ worldwide service network, including technical support, recalibration services, and obsolescence management per IEEE 1451.4 guidelines.
