Product Introduction
The Bently Nevada 330103-00-05-10-02-00 is a precision-engineered 8mm proximity probe from the trusted 3300 XL series, designed for critical industrial monitoring of rotating machinery. It plays a central role in non-contact measurement of shaft vibration and position, using eddy current technology to maintain accurate, real-time data across extreme industrial environments.
This specific model features a 1.0 meter system length and a straight coaxial connector (02-00) at the probe end, offering enhanced ease of installation in deep or straight-run probe ports. Its rugged construction and high temperature tolerance ensure consistent performance across a wide range of applications including turbines, compressors, pumps, motors, and gear-driven equipment.
Backed by the legacy of Bently Nevada, a GE company known globally for machinery protection and condition monitoring systems, this probe meets the industry’s most demanding standards for reliability, accuracy, and durability.

Frequently Asked Questions (FAQ)
-
What is the difference between the “02-00” and “01-05” connector options?
The “02-00” is a straight connector version ideal for direct axial insertions, while “01-05” is a 95-degree booted connector for tighter or angled spaces. -
Can this proximity probe be used in high-temperature zones?
Yes, it is rated for continuous operation up to +120°C, making it suitable for most industrial applications. -
Is calibration required before installation?
No, the probe comes factory-calibrated. Recalibration is only needed if paired with a different length extension or sensor module. -
What output does the probe provide?
It outputs an AC voltage proportional to the distance from the probe tip to the target surface, used to measure vibration or displacement. -
Can the cable length be changed in the field?
No, changing cable length affects calibration. Only use Bently Nevada-certified lengths. -
Is this probe suitable for underwater or submerged applications?
It is IP65 rated but not designed for submerged conditions. For submersible applications, a specialized sealed variant is required. -
What is the tip made of?
The sensing tip is stainless steel with a PEEK insulating sleeve, ensuring durability and consistent performance. -
Is this probe compatible with older Bently Nevada systems?
It is primarily designed for use with the 3300 XL series but can interface with some older systems using conversion accessories. -
Does the probe support axial and radial measurements?
Yes, depending on how it’s mounted relative to the rotating shaft. -
How should the probe be installed?
It should be mounted in a fixed bracket or port aligned with the target shaft, with correct gap distance adjusted during setup.
