Quick Detail

Description

The 330104-01-08-50-01-05 is a high-performance, intrinsically safe 3300 XL 8 mm Proximity Probe, meticulously manufactured by Bently Nevada in the USA for precision condition monitoring in demanding and hazardous industrial environments. As a premier member of the acclaimed 3300 XL series, this eddy current displacement transducer is engineered to perform non-contact, high-fidelity measurement of the dynamic gap between its probe tip and a conductive target surface, such as a rotating shaft. It generates a linear voltage output directly proportional to this distance, delivering critical real-time data essential for comprehensive machinery protection, including parameters for shaft vibration, axial position (float), and Keyphasor reference signals for speed and phase analysis. Its design and performance adhere to the rigorous American Petroleum Institute API 670 standard, making it a trusted sensor for safeguarding critical rotating assets like turbines, compressors, and large pumps across high-stakes industries.

This specific probe configuration is distinguished by its extended reach and certified safety features. It features a compact mechanical profile with a 10 mm unthreaded length and an 80 mm overall case length, allowing for versatile installation in various machinery housings. A key differentiator is its integrated 5.0 meters (16.4 feet) total length of rugged, factory-attached cable. This extended cable length eliminates the immediate need for separate extension cables in many applications, simplifying installation logistics and reducing potential connection points. The cable is terminated with a secure Miniature coaxial ClickLoc connector, complete with a connector protector for enhanced durability and reliable mating. Crucially, this model is certified with CSA, ATEX, and IECEx Approvals, authorizing its direct use in classified hazardous areas with flammable gases or dust, a mandatory requirement for many oil & gas, chemical, and mining applications.

Applications

This 3300 XL 8 mm Proximity Probe is ideally suited for continuous vibration and position monitoring on critical rotating equipment within hazardous locations, such as oil refineries, offshore platforms, and chemical processing plants. Its CSA, ATEX, and IECEx Approvals permit direct installation in Zone 1/2 areas, eliminating the need for additional explosion-proof enclosures. The integrated 5.0-meter cable length provides ample reach for connecting to remotely mounted junction boxes or monitoring systems, making it perfect for monitoring large gas compressors, turbine-generator sets, and process pumps where sensors must be placed at a safe distance from ignition sources.

The probe excels in applications requiring precise axial thrust position monitoring on large machinery. Its compact dimensions (10 mm unthreaded length, 80 mm case length) allow it to fit into the constrained spaces often found around thrust bearing assemblies. The linear output corresponding to its 2 mm linear range provides accurate measurement of shaft axial movement, which is vital for preventing catastrophic metal-to-metal contact in steam turbines, hydro turbines, and large centrifugal compressors used in power generation and LNG facilities, ensuring equipment operates within safe mechanical clearances.

For comprehensive machinery diagnostics and protection, this probe serves as a reliable source for Keyphasor reference and speed measurement. Its ability to accurately detect shaft keyways or notches provides a critical once-per-revolution timing pulse. This signal is fundamental for vibration phase analysis, dynamic balancing, and diagnosing faults like shaft cracks or rotor rubs. The probe’s robust construction and stable output ensure reliable performance even in the high-vibration environments typical of heavy industrial machinery, supporting both operational efficiency and predictive maintenance strategies.

Competitive Advantage

1.Certified Safety for Global Hazardous Area Deployment

The probe's possession of CSA, ATEX, and IECEx Approvals represents a significant competitive edge. This triple certification provides a globally recognized, plug-and-play safety solution for installations in explosive atmospheres. It drastically simplifies compliance for end-users in the oil & gas, chemical, and pharmaceutical industries, reducing project engineering time, certification costs, and risks associated with deploying non-certified equipment in regulated zones.

2.Extended Integrated Cable for Simplified Installation and Reliability

Featuring a generous factory-integrated 5.0-meter (16.4 ft) cable, this model offers exceptional installation flexibility. This extended length often eliminates the need for a separate extension cable, reducing the total number of connections in the signal path. Fewer connections enhance overall system reliability by minimizing potential points of failure, signal degradation, or moisture ingress. This integrated design streamlines procurement, installation, and maintenance, leading to lower total cost of ownership.

3.Robust Construction for Unmatched Durability and Signal Integrity

Built with a PPS probe tip and an AISI 301/304 stainless steel case, the probe is engineered to withstand extreme environmental challenges, including temperature extremes (-55°C to +108°C), corrosive chemicals, and physical abrasion. This premium material combination ensures long-term stability and extends service life. Coupled with its low supply sensitivity (<3 mV/V) and stable 50 Ω output resistance, it guarantees high-fidelity, drift-free signal transmission, which is critical for accurate condition monitoring and early fault detection in demanding 24/7 industrial operations.
