Description

The Bently Nevada 330105-02-12-05-12-05 is a 3300 XL 8 mm Reverse Mount Proximity Probe designed for high-performance vibration and position monitoring in industrial rotating machinery. This transducer system provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface, enabling the measurement of both static (position) and dynamic (vibration) values.

This specific configuration includes a 0.5-meter cable length, a Miniature ClickLoc coaxial connector, and FluidLoc cable technology to prevent oil leakage. The 3300 XL system is fully compliant with API 670 standards for mechanical configuration, linear range, accuracy, and temperature stability, and supports complete interchangeability of components without the need for bench calibration.

Features

• Reverse mount configuration with 3/8-24 UNF threads.
• FluidLoc cable design to prevent fluid migration through the cable.
• Miniature ClickLoc coaxial connector for secure, reliable signal transmission.
• Complete interchangeability with 3300 XL series probes, extension cables, and Proximitor sensors.
• Advanced RFI immunity for operation in harsh industrial environments.
• Agency approvals: CSA, ATEX, and IECEx.

Applications

• Fluid-film bearing machines (turbines, compressors, pumps).
• Centrifugal air and process gas compressors.
• Turbo expanders and high-speed rotating equipment.
• Electric motors and generators with tight internal clearances.
• Keyphasor reference and speed measurement applications.

Technical Specifications

Installation Guidelines

• Ensure the reverse mount holder is securely fixed to the machine casing before inserting the probe.
• Recommended installation torque is 68 N·m (50 ft·lb); do not exceed 163 N·m (120 ft·lb) to avoid damage to the probe or machine.
• Ensure the probe tip is clean and free of debris to maintain measurement accuracy.
• Route cables away from high-EMI sources and ensure proper strain relief.
• System components are backward compatible with non-XL 3300 series 5 mm and 8 mm components.

FAQs

What is the 330105-02-12-05-12-05?

It is a 3300 XL 8 mm Reverse Mount Proximity Probe used for non-contact displacement, position, and vibration measurement in industrial machinery.

Can I replace individual components of the 3300 XL system?

Yes, the 3300 XL system is designed for complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need for individual bench calibration.

What is the purpose of the FluidLoc cable?

The FluidLoc cable is designed to prevent oil or other process fluids from leaking through the cable assembly, which is critical for maintaining the integrity of the machine housing and monitoring system.
