Quick Detail

Description

The 330905-00-05-05-02-05 is a specialized, high-accuracy 3300 NSv Proximity Probe designed by Bently Nevada to address the challenges of small-target displacement sensing and tight-clearance machinery monitoring. As a critical member of the 3300 NSv Proximity Probes series, this eddy current transducer is specifically engineered for applications where a standard 8 mm probe is too large or where the target shaft diameter is significantly small. This specific model features a 0 mm unthreaded length and a 50 mm overall case length, providing a compact, fully-threaded body that allows for precise depth adjustment within specialized mounting brackets or bearing housings.

A primary advantage of the 3300 NSv Proximity Probes is their role as a modern replacement for legacy systems. The 330905-00-05-05-02-05 serves as a direct upgrade path for the older 3300 RAM transducer systems and the 3000/7000 series 190 systems. Unlike standard probes, the 3300 NSv Proximity Probes are optimized for a 1.5 mm (60 mils) linear range, which, while shorter than the 8 mm series, offers superior resolution and signal stability on small shafts or targets with restricted surface area. The probe utilizes a 0.5-meter (20-inch) total length integrated cable terminated with a Miniature coaxial ClickLoc connector, ensuring a vibration-proof link to the extension cable.

Applications

The 330905-00-05-05-02-05 is primarily utilized for Radial Vibration Monitoring on Small-Diameter Shafts. Because standard 8 mm probes suffer from "sideview" interference on small targets, the 3300 NSv Proximity Probe is the preferred solution for high-speed compressors, small motors, and aero-derivative turbines. It provides a stable 200 mV/mil output, allowing operators to detect minute dynamic displacements and imbalances that could indicate bearing wear or incipient mechanical failure in compact rotating machinery.

This probe is frequently employed for Axial Thrust Position Monitoring in restricted spaces. Its 50 mm compact case length and 0 mm unthreaded portion allow it to be installed in shallow mounting ports where space behind the machine casing is limited. By maintaining a 1.0 mm (40 mils) recommended gap setting, the sensor accurately tracks the longitudinal float of the rotor. This is critical for preventing axial contact between stationary and rotating parts in high-pressure pumps and small-scale steam turbines.

The 330905-00-05-05-02-05 serves as a reliable Keyphasor and Speed Sensing tool for centrifugal equipment. By detecting a notch or projection on the shaft, it generates a precise once-per-turn timing pulse essential for phase angle measurements and balancing procedures. Given its wide operating temperature range of up to +177°C, it is particularly effective for speed sensing near hot turbine sections or in offshore marine environments where exposure to extreme heat and salt-laden air is common.

Specifications

Competitive Advantage

1. Optimized Performance for Small Targets

The 3300 NSv Proximity Probes offer a significant advantage over standard 5 mm or 8 mm systems when monitoring small shafts (typically under 76 mm or 3 inches in diameter). The 330905-00-05-05-02-05 minimizes "sideview" effects and electromagnetic interference from surrounding metal, providing a cleaner, more accurate linear signal on small-scale industrial assets that other sensors cannot monitor effectively.

2. Industry-Leading Thermal Resilience

With an operational ceiling of +177°C (350°F), this probe far exceeds the temperature limits of many competing displacement sensors. This extreme thermal tolerance ensures that the 3300 NSv Proximity Probes remain stable and accurate in high-heat zones, such as those found in internal combustion engines or near turbine exhaust seals, where standard sensors would suffer from signal drift or physical degradation.

3. Streamlined Upgrade Path for Legacy Systems

The 330905-00-05-05-02-05 offers a seamless transition for plants still utilizing the discontinued 3000-series or 3300 RAM systems. Because it is designed to interface perfectly with the modern NSv Proximitor, it allows facilities to modernize their machinery protection systems with minimal mechanical modifications, preserving the existing installation footprint while gaining the benefits of modern electronics and Multiple Agency Approvals.
