Description

Technical Overview

The Bently Nevada 330903-00-10-10-02-05 3300 NSv Proximity Probe is a high-precision, non-contact displacement sensing solution engineered for mission-critical machinery protection and condition monitoring in industrial rotating equipment. Manufactured by Baker Hughes (formerly Bently Nevada), a global leader in asset reliability and predictive maintenance technologies, this probe forms an integral component of the industry-standard 3300 XL and 3300 NSv vibration monitoring systems. Designed to operate in harsh environments—including high temperatures, electromagnetic interference, and mechanical vibration—the 330903-00-10-10-02-05 delivers exceptional linearity, repeatability, and thermal stability across its full measurement range. Its robust construction features a stainless steel housing, PTFE-insulated coaxial cable, and hermetically sealed electronics, ensuring long-term reliability in demanding applications such as gas turbines, steam turbines, compressors, centrifugal pumps, and large electric motors. The probe complies with ISO 10816, API 670 (4th Edition), and IEC 61000-6-2/6-4 electromagnetic compatibility standards. Each unit undergoes rigorous factory calibration against NIST-traceable reference standards and is supplied with a certified calibration report documenting sensitivity, linearity error, frequency response, and temperature drift characteristics. This model is offered in new, factory-fresh condition—never refurbished or reconditioned—and carries a comprehensive 24-month limited warranty covering material defects and workmanship. Originating from the United States, it adheres to stringent ASME, ANSI, and RoHS-compliant manufacturing protocols. With compact dimensions (Ø8.5 mm × 110 mm probe body; total cable length 5 meters) and a lightweight design (total assembly weight: 325 g), the 330903-00-10-10-02-05 facilitates seamless integration into space-constrained mounting configurations while maintaining optimal signal integrity and minimal phase lag. Its optimized tip geometry and advanced eddy-current sensing technology enable sub-micron resolution and <±1% full-scale linearity error over the specified operating range, making it ideal for both continuous protection and precision diagnostics.
