Bently Nevada 330103-00-80-10-02-00 3300 XL 8mm Proximity Probe

Product Overview

The Bently Nevada 330103-00-80-10-02-00 is a high-precision 3300 XL 8mm Proximity Probe, a core component of the industry-standard 3300 XL Proximity Transducer System. This non-contacting sensor is designed to measure vibration, radial position, and axial thrust on high-speed rotating machinery. Engineered for extreme reliability, the probe provides an output voltage directly proportional to the distance between the probe tip and the observed conductive target (typically a shaft), enabling the early detection of mechanical imbalances, bearing wear, and misalignment.

Functional Engineering & Signal Accuracy

The 3300 XL 8mm probe represents a significant advancement in eddy current sensor technology. It features a chemically resistant polyphenylene sulfide (PPS) tip, which is molded onto the probe coil to ensure a hermetic seal against oil, water, and industrial contaminants. The probe is designed to operate seamlessly with a 3300 XL Proximitor® Sensor and an extension cable, providing a linear range of 2.0 mm (80 mils). This system is essential for protecting critical assets such as turbines, compressors, motors, and generators in power generation and oil & gas applications.

Technical FAQs

What is the purpose of the ClickLoc™ connector?The 02 connector option features a ClickLoc™ coaxial connector. This gold-plated, corrosion-resistant connector is designed to provide a secure, vibration-proof connection between the probe and the extension cable. It requires only finger-tightening to lock, ensuring signal integrity in high-vibration environments.

How does the total length affect system calibration?The 10 code indicates a 1.0 metre total probe length. It is critical that the combined length of the probe and the extension cable matches the calibration of the Proximitor Sensor (typically 5.0 or 9.0 metres total). Mixing lengths (e.g., using a 1m probe with a 9m cable on a 5m Proximitor) will result in significant calibration errors.

Can this probe be used in high-pressure environments?Yes. The 330103 series probe is designed with a high-pressure seal between the tip and the probe case, rated for pressures up to 700 psi. This allows it to be used in fluid-film bearing housings where oil pressure is present.

Field Engineering & Installation Guide

• Gap Adjustment: During installation, the probe must be "gapped" using a voltmeter. For a standard 3300 XL system, the mechanical gap is usually set so the Proximitor output is -10.0 VDC, which represents the center of the linear range.

• Cable Protection: The probe cable is made of FEP-insulated coaxial wire. While durable, it should be protected by flexible conduit or armor (if the armored option is selected) to prevent mechanical damage or interference from nearby high-voltage lines.

• Target Material: The standard calibration for this probe is AISI 4140 steel. If the shaft material is different (e.g., stainless steel or tungsten carbide), the scale factor will change, and a custom calibration or a "target factor" correction must be applied.

Engineering Advantages

The Bently Nevada 330103-00-80-10-02-00 offers the highest level of stability and interchangeability in the industry. Its wide operating temperature range and robust mechanical design ensure that it can withstand the harshest industrial conditions while maintaining sub-micron measurement accuracy. For B2B procurement, choosing the original 3300 XL 8mm probe ensures full compatibility with the 3500 Monitoring System, maintaining factory safety certifications and preventing catastrophic machinery failure through precise condition monitoring.
