Description
The Bently Nevada 330901-02-47-10-01-00 is a precision component of the 3300 XL NSv Proximity Transducer System, designed for critical vibration and displacement monitoring. This specific model is configured with a 1/4-28 UNF threaded body in an unarmored style, featuring an unthreaded length of 0.2 in and a defining overall case length of 4.7 in. This extended length allows the 330901-02-47-10-01-00 to be installed in deep mounting holes to monitor recessed targets within machinery. 

Engineered for performance in challenging environments, the 330901-02-47-10-01-00 offers significant advancements over previous generations. It possesses markedly increased chemical resistance compared to the legacy 3300 RAM probe, making it suitable for aggressive applications such as process compressors. 

Additionally, its side-view characteristics are superior to those of the older 3000-series 190 probe when gapped at the same distance, reducing measurement error from lateral shaft movement. The 330901-02-47-10-01-00 is supplied as a complete, ready-to-install unit with a total length of 1.0 meter (39 inches). 

It is terminated with a Miniature Coaxial ClickLoc connector that is pre-fitted with a connector protector for environmental sealing. All connectors in the system, including those on the 330901-02-47-10-01-00, are gold-plated brass and feature a positive locking mechanism to prevent loosening under vibration. 

As part of the versatile 3300 NSv series, the 330901-02-47-10-01-00 represents one of many available configurations, which include armored and unarmored versions with thread options like 1/4-28 UNF, 3/8-24 UNF, M8x1, and M10x1. 

The extended 4.7-inch case of the 330901-02-47-10-01-00 makes it an ideal solution for monitoring deep-set bearings, thrust collars, and other critical components in turbines, compressors, and pumps.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What are the defining mechanical dimensions and construction features of the 330901-02-47-10-01-00 probe?
The Bently Nevada 330901-02-47-10-01-00 is a 1/4-28 UNF threaded, unarmored probe with an unthreaded length of 0.2 in and an extended overall case length of 4.7 in, designed for deep-reach installations. Its construction utilizes the patented TipLoc molding method to ensure a robust bond between the probe tip and body, and it incorporates a Viton O-ring to seal differential pressure between the tip and case.
How does the 330901-02-47-10-01-00 improve upon older probe models in terms of environmental and measurement performance?
The 330901-02-47-10-01-00 offers significantly increased chemical resistance compared to the 3300 RAM probe, qualifying it for harsh applications like process compressors. It also provides superior side-view characteristics relative to the 3000-series 190 probe at equivalent gap settings, resulting in more accurate displacement measurements by being less sensitive to lateral target movement.
What is the sealing mechanism and electrical connection specification for the 330901-02-47-10-01-00?
The 330901-02-47-10-01-00 is designed to seal differential pressure using a Viton O-ring located between the probe tip and case. Electrically, it has a total length of 1.0 meter and terminates in a Miniature Coaxial ClickLoc connector made of gold-plated brass, which includes a connector protector. This connector features a positive lock to prevent vibration-induced loosening.
Is the 330901-02-47-10-01-00 compatible with existing monitoring systems, and what does its interchangeability entail?
Yes, the 330901-02-47-10-01-00 is designed for full mechanical and electrical compatibility and interchangeability with Bently Nevada's previous 3300 RAM proximity probe and extension cable systems. This means the 330901-02-47-10-01-00 can be used as a direct, drop-in replacement for a 3300 RAM probe in an existing transducer loop without requiring system recalibration or modification, provided the mechanical dimensions (like the 4.7-in case length) are suitable for the application.
