Quick Detail

Description

The 330709-000-130-10-02-00 is a high-precision 3300 XL 11 mm Proximity Probe, meticulously engineered by Bently Nevada in the USA to deliver exceptional reliability and accuracy in the most demanding industrial condition monitoring applications. As an integral component of the industry-leading 3300 XL transducer system, this eddy current proximity probe is specifically designed for non-contact measurement of shaft displacement, vibration, and position on large rotating machinery. It generates a highly linear voltage output that is directly proportional to the gap between its probe tip and a conductive target surface, providing the critical data needed for effective machinery protection and predictive maintenance strategies in sectors such as power generation, oil and gas, and heavy industry.

This specific 11 mm Proximity Probe model is distinguished by its unique physical configuration, optimized for installations requiring extended reach within the mounting assembly. It features a 0 mm unthreaded length and a significantly longer overall case length of 130 mm, allowing it to be securely mounted through thicker machine casings, bearing housings, or specially designed mounting brackets where standard-length probes are insufficient. The probe is supplied as a complete, ready-to-install unit with an integrated standard cable offering a total length of 1.0 meter (3.3 feet). This cable is terminated with a robust Miniature coaxial ClickLoc connector, which is further safeguarded by an integrated connector protector. This design ensures a secure, vibration-resistant connection and provides excellent strain relief, protecting the electrical interface in harsh environments.

Applications

This 3300 XL 11 mm Proximity Probe is ideally suited for monitoring large-scale axial thrust position and radial vibration on heavy rotating equipment such as utility steam turbines, hydroelectric generators, and large centrifugal compressors. Its extended 130 mm overall case length allows it to be mounted through thick casing walls or complex bearing housing assemblies where standard probes cannot reach the target measurement surface. The generous 4 mm linear range is critical for accurately capturing the significant axial movement and vibration amplitudes typical of these large rotors, providing essential data for protecting thrust bearings and preventing catastrophic rotor-stator contact.

The probe is frequently deployed in applications requiring precise rotor eccentricity and slow roll monitoring during machine startup and shutdown sequences. Its high sensitivity and stable output are crucial for detecting subtle shaft bows or misalignments before a machine reaches full operating speed. The integrated 1.0-meter cable with a secure ClickLoc connector facilitates reliable connections in crowded machinery galleries, while its wide temperature range ensures performance stability during the thermal transients experienced during machine coast-down and heating phases.

In retrofit and upgrade projects for legacy monitoring systems, this specific probe configuration is invaluable. Its physical dimensions and electrical compatibility with the 3300 XL system make it an excellent choice for replacing older, less reliable probes on critical machinery without requiring extensive modifications to existing mounting holes or hardware. The probe's robust construction and environmental resilience make it a reliable long-term sensing solution for continuous condition monitoring in challenging environments such as power plant turbine halls and offshore compression platforms.

Specifications

Competitive Advantage

1.Extended Reach Design for Challenging Mounting Scenarios

Featuring a unique configuration with 0 mm unthreaded length and an extended 130 mm overall case length, this probe is specifically engineered to solve installation challenges where the measurement point is located deep within a machine's structure. This design allows it to traverse thick mounting flanges, insulation layers, or protective sleeves, providing a direct and secure path to the target surface where shorter probes would be inadequate. This eliminates the need for custom adapters or complex mounting solutions, simplifying installation in retrofit applications and specialized machinery.

2.Superior Signal Fidelity and Measurement Stability

The probe delivers outstanding electrical performance, characterized by a wide 4 mm linear range for capturing large displacements and an exceptionally low supply sensitivity of less than 1 mV/V. This combination ensures that the output signal is both highly accurate for large movements and remarkably stable against variations in the system's power supply voltage. This level of stability minimizes false alarms and provides consistently reliable data, which is paramount for making informed maintenance decisions and ensuring the longevity of critical assets.
