Quick Detail

Description

The 330104-16-21-05-01-05 is a high-precision 3300 XL 8 mm Proximity Probe engineered by Bently Nevada for sophisticated industrial machinery protection. As a core component of the world-leading 3300 XL 8 mm Proximity Probes series, this eddy current transducer is specifically designed to measure static and dynamic distances between a probe tip and a target surface. This model features a substantial 160 mm unthreaded length and a 210 mm overall case length, making it ideal for deep-insertion mounting requirements where the probe must reach through thick machine housings or specialized brackets to monitor internal rotating shafts.

Integrating the 330104-16-21-05-01-05 into your monitoring strategy ensures compliance with the rigorous API 670 standard, which defines the industry benchmarks for vibration monitoring systems. The 3300 XL 8 mm Proximity Probes utilize a high-performance Polyphenylene Sulfide (PPS) tip material, which provides exceptional chemical resistance and structural integrity in environments saturated with hot lubricating oils. This specific probe configuration includes a 0.5-meter total length and is equipped with a Miniature coaxial ClickLoc connector, ensuring a secure, vibration-resistant link to the extension cable without the need for specialized tools.

Applications

1.Deep-Reach Radial Vibration Analysis

With its specialized 210 mm case length, this probe is perfectly suited for monitoring radial shaft vibration in heavy-duty machinery where the bearing housing is exceptionally thick. It captures minute shaft movements (up to a 2 mm linear range) caused by imbalance or misalignment, providing the critical data needed for early fault detection in large centrifugal compressors and turbines.

2.Axial Position and Thrust Monitoring

The 330104-16-21-05-01-05 is frequently utilized to monitor the axial "float" of a shaft. By measuring the gap between the probe tip and the thrust collar, it ensures that the rotor remains within safe clearances. This is vital for protecting thrust bearings in high-pressure steam turbines from excessive wear or sudden failure.

3.High-Precision Speed and Keyphasor Detection

In addition to vibration, this 3300 XL 8 mm Proximity Probe provides high-fidelity signals for speed measurement. By detecting a keyway or notch on a rotating shaft, it generates a Keyphasor signal—a once-per-turn pulse essential for phase angle measurements and balancing procedures, enabling engineers to pinpoint the exact location of mechanical faults.

Specifications

Competitive Advantage

1.Extended Geometry for Complex Mounting

Unlike standard short-body probes, the 160 mm unthreaded length and 210 mm case length provide a significant advantage for specialized installations. This "long-reach" design eliminates the need for custom-made extension sleeves, reducing installation complexity and potential points of mechanical failure.

2.Advanced ClickLoc Connector Technology

The inclusion of the Miniature coaxial ClickLoc connector offers a superior connection compared to traditional threaded connectors. The "click" feedback confirms a secure lock, preventing signal intermittent issues caused by machinery vibration, which is a common cause of false alarms in less advanced proximity systems.

3.Total System Interchangeability

A major competitive edge is the ability to swap the 330104-16-21-05-01-05 probe with any other 3300 XL 8 mm component without hardware adjustments. This "plug-and-play" capability reduces spare parts inventory costs and drastically shortens repair times during critical turnarounds or emergency outages.
