Product Introduction

The Bently Nevada 330901-51-82-10-02-00 3300 NSv Proximity Probe is a high-precision non-contact displacement sensor designed for measuring shaft vibration, axial position, and phase reference in compact rotating machinery. Belonging to the 3300 NSv (Narrow Signal Version) family, it is engineered specifically for small and space-constrained machines such as miniature turbines, compressors, gearboxes, pumps, and electric motors where standard 3300 XL probes cannot be installed due to physical limitations.

This probe operates on the eddy current principle, utilizing a high-frequency electromagnetic field to detect the position and vibration of a conductive target surface. When used in combination with a Bently Nevada 3300 NSv Proximitor Sensor and appropriate extension cable, the system provides precise, linear, and stable measurements consistent with API 670 machinery protection standards.

The 330901-51-82-10-02-00 model delivers superior measurement accuracy, enhanced environmental robustness, and high reliability under oil-contaminated or thermally dynamic conditions. It is an essential component for predictive maintenance, vibration diagnostics, and shaft position monitoring, ensuring operational safety and reduced downtime for critical rotating assets.

Applications

The 330901-51-82-10-02-00 Proximity Probe is specifically engineered for precision measurement in environments where space and access are restricted. It is ideally suited for use in small, high-speed, and critical rotating machinery that demands continuous monitoring of vibration and shaft position.

Common application areas include:

• Compact Steam and Gas Turbines – Accurate rotor position and vibration feedback for protection systems.

• Centrifugal Compressors – Monitoring of rotor dynamic behavior and bearing condition.

• Pumps and Gearboxes – Detection of imbalance, looseness, and shaft misalignment.

• Electric Motors and Generators – Shaft displacement and vibration diagnostics.

• Industrial Fans and Blowers – Early warning for rotor instability or mechanical looseness.

• Aerospace and Marine Machinery – Designed for compact rotating drives and auxiliary propulsion systems.

These probes are frequently integrated into Bently Nevada 3500 and 3300 monitoring systems, forming part of an API 670-compliant vibration and position measurement chain.
