Quick Detail

Description

The 330902-00-20-10-02-05 is a specialized, high-precision eddy current sensor within the 3300 NSv Proximity Probes family by Bently Nevada. This specific 3300 NSv Proximity Probes model is meticulously engineered for non-contact displacement measurements in centrifugal compressors, pumps, and other critical rotating machinery where installation space is restricted. As a premium 3300 NSv Proximity Probes solution, it provides a seamless upgrade path for legacy 3300 RAM proximity systems, offering full electrical and mechanical compatibility. By integrating the 330902-00-20-10-02-05, industrial facilities can achieve superior monitoring of vibration and shaft position, ensuring the mechanical integrity of high-speed assets.

Technically, this 3300 NSv Proximity Probes variant features a 0-inch unthreaded length and a 2.0-inch overall case length, optimized for flush-mounting or deep-cavity installations. The 330902-00-20-10-02-05 probe utilizes a 1.0-meter (39-inch) total length cable equipped with the gold-plated miniature coaxial ClickLoc connector. A standout feature of these 3300 NSv Proximity Probes is their advanced chemical resistance, which protects the sensor tip and body from corrosive process fluids and lubricants. Furthermore, the 3300 NSv Proximity Probes design offers enhanced "side-view" characteristics, which minimize interference from adjacent metal surfaces when monitoring small-diameter shafts or targets with limited clearance.

Durability is at the core of the 330902-00-20-10-02-05. These 3300 NSv Proximity Probes are manufactured using the patented TipLoc molding method, creating an inseparable bond between the probe tip and the stainless steel body. Additionally, the CableLoc design ensures the cable remains securely attached even under 220 N (50 lb) of pull force. With multiple agency approvals, the 3300 NSv Proximity Probes are suitable for deployment in hazardous areas worldwide. Whether used for radial vibration or axial thrust measurement, the 330902-00-20-10-02-05 3300 NSv Proximity Probes deliver the high-fidelity signal output necessary for modern predictive maintenance and machine protection strategies.

Applications

The 330902-00-20-10-02-05 3300 NSv Proximity Probes are primarily applied to small-bore rotating machinery where traditional 8 mm probes are too large to install. Due to their optimized side-view characteristics, these probes are ideal for monitoring radial shaft vibration and axial position in high-speed compressors and aeroderivative turbines. The 1.5 mm (60 mils) linear range allows for precise tracking of shaft displacement within fluid-film bearings, providing essential data to prevent catastrophic rotor-to-stator contact.

This specific 3300 NSv Proximity Probes model is frequently utilized in process-compressor applications where exposure to corrosive environments is expected. The probe’s enhanced chemical resistance ensures long-term stability in the presence of oils and harsh process gases. With a 1.0-meter total length and a 2.0-inch case, it serves as a robust sensing element in compact machinery housings, delivering a steady 45 Ω output resistance signal back to the Proximitor sensor for continuous machinery health monitoring.

In environments with extreme temperature fluctuations, the 330902-00-20-10-02-05 excels by maintaining accuracy across an operating range of -52°C to +177°C. This makes it a critical component for Keyphasor reference and speed measurement on auxiliary equipment in both cryogenic and high-heat industrial zones. The miniature ClickLoc connector ensures that even in high-vibration settings, the electrical connection remains secure, providing clean pulses for overspeed protection and phase-triggering diagnostics.

Specifications

Competitive Advantage

1. Superior Small-Target Performance and Side-View Resistance

The 330902-00-20-10-02-05 offers a significant technical advantage over standard 3000-series probes by providing a narrower magnetic field. This allows the 3300 NSv Proximity Probes to accurately measure targets as small as 9.5 mm (0.375 in) in diameter without the "side-view" interference from the surrounding bearing housing. This precision ensures that the vibration data remains pure and unaffected by the probe's proximity to adjacent metal walls, which is a common failure point in compact sensor installations.

2. Enhanced Mechanical Robustness with TipLoc and CableLoc

Bently Nevada has incorporated patented TipLoc and CableLoc technologies into the 3300 NSv Proximity Probes. The 330902-00-20-10-02-05 features a probe tip that is chemically bonded and mechanically locked to the body, preventing tip loss in high-pressure or high-flow environments. Furthermore, the cable attachment can withstand a 50 lb pull strength, which is significantly higher than industry standards, drastically reducing the risk of sensor failure during installation or routine maintenance.

3. Broad Environmental Adaptability and Agency Approvals

Operating from -56°C to +170°C, the 330902-00-20-10-02-05 is built for the most demanding industrial climates. Its "Multiple Approvals" status means it is ready for global deployment in hazardous zones without requiring additional certification paperwork. The gold-plated ClickLoc connectors provide a corrosion-resistant, low-resistance connection that outperforms standard brass connectors, ensuring signal stability over the life of the machine monitoring system.
