Quick Detail

Description

The 330905-00-25-05-01-05 3300 NSv Proximity Probe is a sophisticated, high-accuracy eddy-current transducer designed for demanding industrial vibration and displacement monitoring. Engineered and manufactured in the USA by Bently Nevada, this advanced proximity probe belongs to the innovative 3300 NSv series, offering a strategic upgrade path for modernizing legacy monitoring systems. Specifically, this model serves as a direct, high-performance replacement for older 3300 RAM Transducer Systems or the 3000-series/7000-series 190 Transducer Systems. A key advantage for users of existing 3300 RAM setups is backward compatibility; the system can be upgraded by simply replacing the Proximitor Sensor with the new 3300 NSv Proximitor, while retaining the original probe and cable. However, for transitions from the older 3000-series or 7000-series systems, a complete replacement of the probe, extension cable, and Proximitor with NSv components is required to unlock the full potential of enhanced diagnostic capabilities and system performance.

This particular 3300 NSv Proximity Probe configuration is defined by its extended 250 mm overall case length and a focused 0.5-meter total cable length, making it ideal for installations requiring a long probe body to reach measurement points within deep machinery cavities. It delivers exceptional measurement precision with a standard scale factor of 7.87 V/mm (200 mV/mil). Distinguished by its enhanced sideview capability and optimized small target characteristics, this probe features a 1.5 mm linear range. While this range is shorter than some XL-series models, it offers superior accuracy for applications monitoring smaller, precise displacements, outperforming the legacy 190 Transducer System.

Applications

The 330905-00-25-05-01-05 3300 NSv Proximity Probe is expertly suited for monitoring critical high-speed rotating equipment in the power generation and petrochemical sectors, such as gas turbines, steam turbines, and centrifugal compressors. Its 250 mm case length allows it to be installed through thick thermal insulation or deep bearing housings to reach the measurement surface on the shaft. The precise 1.5 mm linear range and high scale factor enable accurate detection of minute radial vibrations and shaft position changes, which are vital for identifying imbalances, misalignments, and incipient bearing failures before they lead to catastrophic breakdowns.

This probe is an optimal solution for machinery with space constraints and specific upgrade requirements. Its compact sensor head and 0 mm unthreaded length facilitate installation in tight geometric spaces where longer probes cannot fit. For facilities operating a 3300 RAM system, this probe offers a cost-effective upgrade path, as it can be integrated with the existing probe and cable by simply upgrading the Proximitor to the NSv version, minimizing retrofit downtime and capital expenditure while significantly enhancing monitoring accuracy and diagnostic functionality.

Specifications

Competitive Advantage

1. Extended-Reach Design for Deep or Insulated Machinery Cavities

This specific 3300 NSv Proximity Probe model features a substantial 250 mm overall case length, a distinguishing characteristic that provides a critical advantage for installations where the measurement point is located deep within a machine casing or behind layers of thermal insulation. This extended reach eliminates the need for custom mounting adapters or invasive machine modifications, enabling direct and secure sensor placement for accurate data acquisition in applications inaccessible to standard-length probes.

2. Strategic, Cost-Effective System Upgrade Path

A significant competitive edge of the 3300 NSv series is its designed upgrade flexibility. For users of the 3300 RAM Transducer System, this probe enables a streamlined and economical modernization. The existing probe and extension cable can be retained, requiring only the Proximitor Sensor to be replaced with the advanced NSv Proximitor. This strategic approach dramatically reduces the cost and complexity of system enhancements, allowing facilities to benefit from next-generation diagnostics without a full sensor suite replacement.

3. Robust Construction for Extreme Environmental Durability

Engineered with a AISI 304 stainless steel housing and a Polyphenylene Sulfide (PPS) tip, this probe is built to survive in the most aggressive industrial settings. Its certified operating temperature range of -42°C to +175°C ensures reliable performance from arctic cold to intense heat, far exceeding the capabilities of many standard sensors. This combination of premium materials and extreme temperature tolerance guarantees long-term measurement stability, minimal drift, and reduced maintenance needs, resulting in a lower total cost of ownership over the asset's lifecycle.
