Quick Detail

Description

The 330907-05-30-05-02-00 3300 NSv Reverse Mount Probe is a state-of-the-art, non-contact eddy current displacement transducer engineered specifically for applications requiring a compact, robust, and precisely configured sensing solution. As a specialized variant within the advanced 3300 NSv Proximity Probe series from Bently Nevada, this Reverse Mount Probe is characterized by its unique mechanical geometry designed for installations where traditional probe orientation is constrained or impractical. This model features a 0.5-inch minimum unthreaded length and a concise 3-inch overall case length, optimized for integration into tight spaces within machinery housings, bearing assemblies, and gearboxes.

This proximity probe is engineered to deliver exceptional reliability and signal integrity in monitoring critical parameters such as shaft vibration, radial position, and dynamic runout on high-speed rotating equipment. It operates on the principle of inducing eddy currents in a conductive target, converting the physical gap between its tip and the target into a highly stable, linear electrical signal. The probe is supplied with a standard 0.5-meter (1.6-foot) integrated cable, terminated with a secure miniature coaxial ClickLoc connector. This connector system ensures a vibration-resistant, positive-lock connection that prevents accidental disconnection and simplifies field wiring, contributing to faster and more reliable installation.

Applications

This Reverse Mount Probe is ideally suited for monitoring radial shaft vibration and position in gearboxes, integrated motor-drive systems, and compact turbomachinery where internal space is severely limited. Its unique 3-inch overall case length and specific mounting configuration allow it to be installed in orientations where standard forward-mount probes cannot physically fit, enabling critical measurements in designs with high packaging density.

The probe excels in applications on process gas compressors, screw compressors, and multi-stage pumps within the oil & gas and petrochemical industries. Its enhanced construction offers reliable performance in environments exposed to synthetic lubricants, process gases, and mild chemical vapors. The 0.5-meter cable with ClickLoc connector provides just enough length for clean routing to a nearby junction box, minimizing dangling cables and potential snag points in crowded machinery skids.

It serves as a perfect drop-in replacement for legacy proximity probes in system modernization projects on turbines, generators, and large fans. The probe’s full electrical compatibility ensures it works seamlessly with existing 3300 monitor frames and extension cables. Its ability to operate reliably across the wide -55°C to +175°C temperature range makes it a robust choice for equipment subject to significant thermal cycling, from cold startup conditions to full-load operating temperatures, ensuring consistent data for condition monitoring and protection.

Specifications

Competitive Advantage

1. Optimized Mechanical Design for Constrained Spaces

The 330907-05-30-05-02-00 model is specifically engineered as a Reverse Mount Probe with a compact 3-inch overall length and a 0.5-inch unthreaded section. This unique form factor is a decisive advantage for OEMs and maintenance teams dealing with machinery where internal clearances prohibit the use of standard-length probes. It enables the implementation of critical vibration and displacement monitoring in applications that were previously inaccessible or required costly custom design changes.

2. Seamless Retrofit and System Compatibility

A primary competitive advantage of this 3300 NSv probe is its guaranteed mechanical and electrical interchangeability with earlier-generation proximity probes, such as the 3300 RAM series. This allows plant operators to upgrade their sensing technology during turnaround periods without modifying mounting holes, changing extension cables, or recalibrating their entire monitoring system. It significantly reduces engineering effort, downtime, and the total cost of ownership for modernizing legacy protection systems.

3. Robust Construction for Demanding Service

Built to withstand harsh industrial environments, this probe combines a wide operating temperature range (-55°C to +175°C) with improved material resistance to common industrial fluids. When paired with the secure ClickLoc connector and a ruggedized cable interface, it delivers exceptional long-term reliability. This durability minimizes unscheduled maintenance, reduces the risk of signal failure due to mechanical or environmental stress, and provides a more dependable data source for predictive maintenance programs compared to less robust alternatives.
