Quick Detail

Description

The 330104-02-08-05-01-00 represents a premium, high-precision 3300 XL 8 mm Proximity Probe, meticulously engineered by Bently Nevada in the USA for the most demanding industrial condition monitoring applications. This advanced eddy current proximity transducer is specifically designed for non-contact, highly accurate measurement of the dynamic gap between its probe tip and a conductive target surface, such as a rotating shaft. It generates a voltage output with a precise linear relationship to this gap, delivering indispensable real-time data for critical machinery protection parameters, including dynamic vibration, static position (e.g., shaft runout and axial float), and rotational speed via Keyphasor reference signals. As an integral component of the industry-leading Bently Nevada 3300 XL monitoring system, this proximity probe is built to deliver unmatched reliability, forming the foundational sensor element for safeguarding high-value rotating assets like turbines, compressors, and large motors across critical industries.

This specific 8 mm Proximity Probe model features a compact mechanical design optimized for installations where spatial constraints are paramount. It is characterized by a 20 mm unthreaded length and an 80 mm overall case length, enabling secure installation within narrow bearing housings, gearbox casings, and other confined machinery spaces. The probe is supplied as a complete, ready-to-install unit, featuring an integrated, rugged cable with a total length of 0.5 meters (1.6 feet). The cable is terminated with a secure Miniature coaxial ClickLoc connector, which is further protected by an integrated connector protector to ensure exceptional durability, strain relief, and reliable mating in high-vibration environments, thereby simplifying the connection to extension cables or compatible Proximitor sensors.

Applications

This 3300 XL 8 mm Proximity Probe serves as the primary sensor for continuous radial vibration monitoring on rotating machinery equipped with fluid-film bearings. Its 2 mm linear range and wide operating temperature range from -56°C to +117°C enable it to accurately capture minute dynamic displacements caused by imbalance, misalignment, or incipient mechanical faults. Its compact form factor, with a 20 mm unthreaded length and 80 mm overall case length, allows for easy installation in the confined spaces of steam turbine bearings, centrifugal compressor housings, and large fan assemblies, providing essential data for predictive maintenance and preventing catastrophic failures.

The probe is equally critical for precise axial (thrust) position monitoring. By measuring the gap between the probe tip and a shaft's thrust collar or shoulder, it delivers real-time data on axial shaft movement. This is vital for ensuring safe operating clearances between rotating and stationary components and for protecting thrust bearings from overload. It is a standard configuration for monitoring axial position in critical equipment such as gas turbines, steam turbines in power plants, and high-pressure pumps on offshore platforms, ensuring operation within designed safety limits.

As a reliable source for Keyphasor reference and rotational speed measurement, this probe accurately detects keyways or notches on a shaft to generate a precise once-per-revolution pulse signal. This Keyphasor signal is the fundamental benchmark for vibration phase analysis, dynamic balancing, and advanced machinery diagnostics. Furthermore, its high-frequency response capability makes it suitable for accurate speed measurement and integration into electronic overspeed protection systems, providing real-time rotational speed feedback to control and safety systems.

Specifications

Competitive Advantage

1.Optimized Compact Design for Easy Plug-and-Play Installation

Engineered for space-constrained applications, this probe's compact dimensions—featuring a 20 mm unthreaded length and an 80 mm overall case length—enable effortless installation into standard, tight-tolerance bearing housing openings. The complete, ready-to-deploy package includes an integrated 0.5-meter cable with a Miniature coaxial ClickLoc connector and protector, ensuring rapid, reliable, and vibration-resistant field connections. This design significantly reduces installation complexity, labor time, and overall commissioning costs.

2.Premium Material Construction and Exceptional Environmental Resilience

Built for longevity in extreme conditions, the probe utilizes top-tier materials. The probe tip is made from high-performance Polyphenylene Sulfide (PPS), offering excellent thermal stability and resistance to chemicals and oils. The probe case is constructed from durable AISI 301 or 304 Stainless Steel, providing superior corrosion resistance and mechanical strength. Its wide operating temperature range (-56°C to +117°C) guarantees stable performance in diverse environments, from arctic cold to extreme heat near process equipment, minimizing the need for additional environmental protection.

3.High-Accuracy Signal Output and Unmatched System Interchangeability

The probe delivers precise measurement with a 2 mm linear range and stable 53 Ω output resistance, enabling accurate gap detection. Its superior supply sensitivity (less than 3 mV/V) ensures a stable output voltage that is highly resistant to input power fluctuations, resulting in consistent and reliable data. As a standardized component within the 3300 XL system, it is fully interchangeable with other series-compatible extension cables and Proximitor sensors without requiring field calibration, simplifying inventory management, maintenance procedures, and system scalability.
