Product Introduction
The Bently Nevada 330907-05-30-05-02-00 is part of the 3300 NSv (Narrow Side View) series, specifically designed for applications where standard proximity probe systems cannot operate effectively due to physical space constraints or target limitations. This Reverse Mount Probe offers a compact sensing solution for small target applications, particularly in environments such as small steam or gas turbines, gearboxes, and rolling element bearing machines. The 3300 NSv system is recognized for its precision, durability, and reliability, even under challenging industrial conditions.
This particular configuration — 05-30-05-02-00 — designates a 0.5 meter standard reverse mount configuration, and a standard connector style. The probe is engineered to ensure accurate and stable vibration and displacement measurements in tight, high-speed rotating machinery.

Frequently Asked Questions (FAQ)
-
What does “NSv” stand for in Bently Nevada 3300 NSv?
NSv means Narrow Side View, indicating the probe’s design is optimized for small or restricted spaces. -
Can the 330907-05-30-05-02-00 probe be used with other proximitor sensors?
It is specifically matched with 3300 NSv proximitor sensors. Compatibility with other models may lead to incorrect readings. -
Is the reverse mount probe suitable for hazardous environments?
The probe can be used in hazardous environments when combined with properly rated proximitor sensors and barriers. -
What is the difference between standard and reverse mount probes?
Standard probes are front-mounted while reverse mount probes are inserted from the opposite side of the mounting surface. -
Can I replace the probe without replacing the extension cable?
Yes, the modular design allows replacement of individual components, provided connectors remain intact and compatible. -
What’s the expected lifespan of this probe?
Under normal industrial conditions, the probe lasts several years. Lifespan can vary depending on environment and vibration levels. -
Is it compatible with condition monitoring systems?
Yes, it is fully compatible with Bently Nevada condition monitoring systems, including System 1 software. -
What is the maximum temperature this probe can withstand?
The operating temperature range is -35°C to +120°C. -
What’s the impact of cable length on sensitivity?
The total system length (probe + extension cable) must match the proximitor sensor for accurate sensitivity. Mismatching can lead to errors. -
How is the probe mounted in a reverse mount configuration?
It is inserted from the back side of the mounting bracket using the threaded body and secured with locknuts or sleeves.
