Quick Detail

Description

The 330902-36-89-05-01 stands as a pinnacle of engineering within the 3300 NSv Proximity Probes series, a next-generation line of non-contact, eddy-current displacement sensors crafted for the most demanding machinery protection applications. Designed and manufactured by Bently Nevada in the USA, these advanced Proximity Probes deliver unparalleled precision in measuring shaft vibration, rotor position, and axial displacement, serving as the critical eyes for predictive maintenance and asset protection strategies in power generation, oil & gas, and heavy industrial sectors. The core technology of the 3300 NSv Proximity Probes converts minute changes in the gap between its probe tip and a conductive target into a highly linear and stable voltage signal, enabling operators to monitor both dynamic motion and static position with exceptional accuracy.

Engineered for superior resilience, this specific model exemplifies enhanced performance under duress. A key advancement of the 3300 NSv Proximity Probes is their significantly improved chemical resistance compared to legacy models, allowing them to withstand prolonged exposure to aggressive lubricants, process fluids, and corrosive environments without degradation of signal integrity or mechanical form. The probe body, with an overall case length of 8.9 inches, is constructed for durability. It incorporates patented innovations such as the TipLoc molding for an indestructible tip-to-body bond and the CableLoc design, which secures the cable with a remarkable 220 N (50 lb) pull strength, ensuring reliability in high-vibration settings.

Furthermore, the 330902-36-89-05-01 is designed with seamless integration and backward compatibility in mind. It is mechanically and electrically interchangeable with earlier 3300 RAM probe systems, allowing for straightforward performance upgrades without costly system overhauls.

Applications

1.Critical Rotating Machinery Vibration and Position Monitoring

The primary application of the 3300 NSv Proximity Probes is the continuous, high-precision monitoring of radial vibration and axial position in essential equipment such as steam turbines, gas turbines, centrifugal compressors, and large pumps. Their 1.5 mm (60 mils) linear range and stable output are crucial for detecting imbalances, misalignments, and thrust bearing wear.

2.Retrofit and Upgrade Solution for Legacy Monitoring Systems

Due to its direct mechanical and electrical compatibility with previous 3300 RAM probe systems, this probe is ideally suited for modernizing existing installations. It allows plants to enhance monitoring capabilities and chemical resistance without modifying mounting points or replacing entire sensor suites, protecting prior investments.

3.Monitoring in Chemically Aggressive and High-Temperature Environments

With enhanced chemical resistance and a wide operating temperature range (-55°C to +170°C), this probe is designed for challenging applications in refineries, chemical plants, and offshore platforms where exposure to process fluids, oils, and extreme heat is common, ensuring long-term reliability where standard probes may fail.

4.Secure Monitoring in High-Vibration Applications

The patented CableLoc and TipLoc features, combined with the locking ClickLoc connector, make the 3300 NSv Proximity Probes exceptionally resistant to loosening or damage caused by sustained mechanical vibration. This makes them ideal for use on reciprocating compressors, engine-driven equipment, and other high-shock machinery.

Specifications

Competitive Advantage

1.Enhanced Chemical and Environmental Durability

A primary advantage of the 3300 NSv Proximity Probes is their superior construction, offering greater resistance to oils, coolants, and corrosive agents than earlier generations. This extends service life and maintains measurement accuracy in dirty, wet, or chemically exposed industrial environments, reducing replacement frequency and maintenance costs.

2.Patented Mechanical Locking and Strain Relief Systems

The integration of TipLoc (for probe tip) and CableLoc (for cable) technologies provides unmatched mechanical robustness. These patented designs prevent the most common failure modes—tip separation and cable pull-out—ensuring sensor integrity even under extreme vibration and physical stress, which is a clear differentiator from competitors.

3.Guaranteed Backward Compatibility and Easy Integration

This probe is designed for seamless drop-in replacement and upgrade within existing 3300-series infrastructure. Its full compatibility with 3300 RAM system cabling and Proximitors eliminates retrofit complexity, minimizes downtime during upgrades, and simplifies spare parts inventory, offering a clear path to improved performance.

4.Wide Operational Temperature Range for Extreme Conditions

Engineered to perform reliably from -55°C to +170°C, the 3300 NSv Proximity Probes operate consistently in both freezing outdoor installations and high-temperature turbine casings. This wide tolerance ensures stable signal output and sensor survival in environments that would compromise lesser probes.

5.Secure Connection with Gold-Plated ClickLoc Connector

The use of gold-plated brass ClickLoc connectors ensures a low-resistance, corrosion-resistant electrical connection that locks securely in place. This design prevents signal interruption due to connector loosening from vibration or thermal cycling, guaranteeing continuous and reliable data transmission to the monitoring system.
