Quick Detail

Description

The Bently Nevada 330104-04-10-05-01-00 3300 XL 8 mm Proximity Probe represents the pinnacle of eddy current displacement sensing technology, engineered for machinery protection and condition monitoring of high-value rotating assets. This specific configuration features a 100 mm overall case length with a 40 mm unthreaded length, providing versatile mounting options to suit a wide array of thrust bearing and radial vibration measurement points on turbines, compressors, and large pumps. The probe is delivered with a 0.5 meter (1.6 feet) integrated standard cable, terminated with a reliable miniature coaxial ClickLoc connector, making it ideal for installations where the Proximitor sensor is located in close proximity, thereby reducing cable clutter and simplifying cabinet management.

At the heart of the probe's performance is its Polyphenylene Sulfide (PPS) sensing tip, a material chosen for its exceptional dimensional stability, electrical insulating properties, and resistance to chemical attack from common industrial lubricants and process fluids. This tip is secured using the proprietary TipLoc molding process, which creates an unparalleled mechanical bond to the AISI 303 or 304 stainless steel case, virtually eliminating the risk of tip separation even under extreme vibration and thermal cycling within its broad operating temperature range of -60°C to +100°C. This robust construction ensures the probe delivers a consistent, highly linear output across its full 2 mm (80 mil) linear range, translating minute changes in shaft position or dynamic motion into precise electrical signals.

Applications

1.Radial Vibration and Eccentricity Monitoring

This 3300 XL 8 mm Proximity Probe is the industry-standard choice for monitoring rotor radial vibration and eccentricity in steam turbines, generators, and centrifugal compressors. Its 2 mm linear range and highly stable output enable precise capture of shaft dynamic motion, providing critical data for the early detection of faults such as unbalance, misalignment, or shaft bending. The design featuring a 100 mm overall case length and 40 mm unthreaded length allows for flexible installation into various bearing housing tap points, enabling continuous health monitoring of rotating components.

2.Axial Position and Thrust Bearing Monitoring

For critical equipment like steam and gas turbines, monitoring axial displacement is essential for protecting thrust bearings. The probe's compact construction and rugged PPS probe tip allow it to withstand the high-temperature environment (up to 100°C) near thrust collars. Its precise displacement measurement capability effectively monitors rotor axial float, preventing catastrophic bearing wear or rotor rub incidents caused by excessive axial forces, making it an indispensable component in machinery protection systems.

3.Keyphasor Measurement and Speed Reference

This probe is also well-suited for Keyphasor applications, providing accurate rotational speed and phase angle information by creating a single physical reference point (such as a keyway or notch) on a shaft. Its fast frequency response and reliable output signal form the basis for vibration phase analysis, balancing corrections, and torsional vibration monitoring. Paired with the 0.5 meter integrated cable and ClickLoc connector, it enables a clean, secure connection at space-constrained Keyphasor installation points, ensuring distortion-free transmission of the reference signal.

Specifications

Competitive Advantage

1.Exceptional Mechanical Robustness and Long-Term Stability

Thanks to the patented TipLoc molding process and AISI 303/304 stainless steel case, the probe achieves a permanent, high-strength bond between the tip and the casing. Combined with the superior chemical resistance and dimensional stability of the PPS probe tip material, it ensures the probe delivers repeatable and precise measurements over decades of service, even in harsh environments ranging from -60°C to +100°C, significantly reducing false alarms or maintenance demands caused by probe performance drift.

2.Optimized Installation Flexibility and System Integration Convenience

The unique combination of a 40 mm unthreaded length and 100 mm overall length provides engineers with greater flexibility for installation depth adjustment, accommodating a wider variety of machine tap point designs. The factory-installed 0.5 meter standard cable and miniature coaxial ClickLoc connector eliminate the hassle of field-terminating cables, not only providing a vibration-resistant connection to prevent intermittent signal loss but also simplifying inventory management (no need to order long cables separately) and accelerating installation and maintenance speed, significantly reducing the total cost of ownership.
