Quick Detail

Description

The 330104-03-09-50-02-00 3300 XL 8 mm Proximity Probe is a high-precision eddy current displacement transducer engineered and manufactured by Bently Nevada in the USA, serving as a core component for critical rotating machinery condition monitoring and failure prevention. As a flagship model in the 3300 XL product line, this proximity probe is designed to deliver millimeter-level gap measurement accuracy in extreme industrial environments, converting the physical distance between its probe tip and conductive target surfaces into a stable, linear voltage signal that reflects shaft vibration, axial position, Keyphasor reference, and rotational speed. Boasting a 30 mm unthreaded length and 90 mm overall case length, the 330104-03-09-50-02-00 proximity probe features a rugged, compact structure with dimensions of 1.9x1.5x108cm and a 0.15kg lightweight build, enabling flexible installation in bearing housings, turbine compartments, and compressor units without requiring extensive equipment modification.

Equipped with a 5.0-meter (16.4 feet) long standard cable terminated with a miniature ClickLoc coaxial connector, the 330104-03-09-50-02-00 proximity probe ensures long-distance, noise-free signal transmission and plug-and-play compatibility with all 3300 XL series extension cables and Proximitor sensor modules—eliminating the need for complex field or bench calibration and enabling rapid replacement during emergency maintenance. Manufactured in strict compliance with the American Petroleum Institute (API) 670 standard, this proximity probe operates reliably across an extreme temperature range of -58°C to +108°C (-66°F to +213°F), withstanding exposure to lubricating oils, corrosive gases, and high particulate matter. Its probe tip is crafted from chemically resistant Polyphenylene Sulfide (PPS), while the housing utilizes durable AISI 301/304 stainless steel, ensuring superior long-term durability and stability even in harsh operating conditions.

Applications

The 330104-03-09-50-02-00 3300 XL 8 mm Proximity Probe is primarily utilized for continuous radial vibration monitoring of fluid-film bearing machinery, including steam turbines, centrifugal compressors, and large industrial fans across power generation, manufacturing, and general industrial sectors. Its 2 mm linear range and wide operating temperature tolerance enable accurate detection of minute shaft displacements caused by imbalance, misalignment, or early-stage bearing failures, providing maintenance teams with early warning to prevent catastrophic equipment breakdowns.

With its precise linear voltage output proportional to target gap distance, this proximity probe excels in axial (thrust) position monitoring for heavy-duty rotating equipment such as hydroelectric turbines and gas compressors. It tracks shaft float in real time, ensuring that rotating and stationary components maintain safe clearance distances, which is critical for protecting thrust bearings and avoiding costly mechanical collisions in high-speed machinery operations.

The 330104-03-09-50-02-00 proximity probe serves as a reliable source for Keyphasor reference signals and rotational speed measurement, supporting phase analysis, rotor balance correction, and electronic overspeed protection systems. Its 5.0-meter long cable is ideal for installations where monitoring racks are located far from the measurement point, making it suitable for large-scale industrial plants and remote machinery monitoring setups that require long-distance signal transmission without attenuation.

Specifications

Competitive Advantage

1.API 670 Compliance for Critical Industrial Reliability

Manufactured in strict adherence to the American Petroleum Institute (API) 670 standard, the probe meets rigorous requirements for linearity, temperature stability, and component interchangeability. This compliance makes it a trusted choice for monitoring "Category 1" critical machinery in oil & gas and power generation sectors, ensuring operational safety and regulatory compliance without additional certification costs.

2.Tool-Free Interchangeability for Rapid Maintenance

The probe supports direct, calibration-free pairing with all 3300 XL series extension cables and Proximitor modules, simplifying spare parts inventory management and enabling emergency replacement within minutes. This feature minimizes unplanned downtime for critical rotating equipment, a key advantage over non-compatible sensors that require time-consuming bench calibration.

3.Long-Cable Design for Flexible Installation Layouts

Equipped with a 5.0-meter (16.4 feet) integrated cable, the probe eliminates the need for additional extension cables in long-distance installations, reducing signal loss at connection points and simplifying on-site wiring. This design is particularly valuable for large industrial plants and remote monitoring setups, lowering installation labor costs and enhancing system reliability.
