Description

Technical Overview

The Bently Nevada 330902-00-95-05-02-00 3300 NSv Probe is a high-precision, non-contact eddy-current displacement sensor engineered for mission-critical machinery protection and condition monitoring in industrial rotating equipment applications. Manufactured by Baker Hughes (formerly Bently Nevada), a global leader in asset reliability solutions, this probe forms the foundational sensing element of the industry-standard 3300 Series vibration and position monitoring systems. Designed to operate reliably under extreme thermal, mechanical, and electromagnetic conditions—including high temperatures, aggressive chemical environments, and intense vibration—the 330902-00-95-05-02-00 delivers exceptional linearity, repeatability, and long-term stability. Its advanced coil architecture and optimized ceramic insulator ensure minimal phase shift and signal distortion across its full measurement range, enabling accurate shaft relative displacement, axial position, differential expansion, and gap voltage measurements. The probe complies with ISO 10816, API 670 (4th Edition), and IEC 61000-6-2/6-4 electromagnetic compatibility standards. It is supplied as new, factory-fresh inventory—never refurbished or previously installed—with full traceability to original Bently Nevada production lot records. Each unit undergoes rigorous 100% functional testing, including sensitivity calibration verification, frequency response sweep, and thermal drift validation at ±5 °C and +70 °C ambient extremes. Backed by a comprehensive 24-month limited warranty covering material defects and workmanship, this probe guarantees operational integrity for critical infrastructure in power generation, oil & gas, petrochemical, and turbomachinery OEM installations.

Detailed Specifications

Key Features

• Precision Calibrated Sensitivity: Factory-calibrated to ±1.5% full-scale accuracy with NIST-traceable documentation; includes individual calibration certificate with serial-matched slope and null data.
