BENTLY 330105-02-12-05-02-05 sensor probe

Product Dimensions：

The Bently Nevada 330105-02-12-05-02-05 is a specialized 3300 XL 8mm Reverse Mount Proximity Probe. It is a core component of the 3300 XL Proximity Transducer System, used globally for industrial machinery protection and condition monitoring.

1. Product Detailed Description

This probe is an eddy-current sensor designed to measure the distance between the probe tip and a rotating shaft (or other conductive surfaces) without physical contact. The “Reverse Mount” configuration allows the probe to be installed from the outside of a machine housing into a threaded hole, making it ideal for tight spaces where internal mounting is impossible.

Part Number Breakdown:

• 330105: 3300 XL 8mm Reverse Mount Probe.

• -02: Unthreaded length (0.2 inches).

• -12: Overall case length (1.2 inches).

• -05: Total length of the probe cable (0.5 meter / 1.6 feet).

• -02: Connector option (Miniature ClickLoc coaxial connector).

• -05: Agency approval (Multiple Approvals: CSA, ATEX, IECEx).

2. Technical Parameters

The performance is highly stable when paired with a 3300 XL Proximitor Sensor and extension cable.

3. Product Advantages

• High Precision: Offers industry-leading accuracy for vibration and displacement monitoring, fully complying with API 670 standards.

• ClickLoc™ Connectors: Gold-plated, corrosion-resistant connectors that “click” when tight, preventing loosening due to vibration without needing special tools.

• Interchangeability: Probes, cables, and sensors are fully interchangeable, eliminating the need for individual bench calibration.

• Durability: Designed for harsh industrial environments, featuring high resistance to chemical exposure and extreme temperatures.

• Backward Compatibility: Works seamlessly with non-XL 3300 series 5mm and 8mm components.

4. Cautions & Maintenance

• Target Material: Specifications are based on an AISI 4140 steel target. Using other materials (like aluminum or stainless steel) will require recalibration as the scale factor will change.

• Minimum Gap: Ensure a minimum gap of 0.25 mm (10 mils) to avoid “bottoming out” the signal.

• Cable Handling: Avoid sharp bends or pinching the coaxial cable, as this can change the capacitance and affect measurement accuracy.

• Installation Torque: Do not over-tighten the probe into the mounting bracket; follow the recommended torque settings to prevent casing damage.

5. Product Applications

This probe is primarily used in Condition Monitoring Systems (CMS) for heavy rotating machinery:

• Radial Vibration: Monitoring shaft vibration in fluid-film bearing machines (pumps, compressors, turbines).

• Axial Position: Measuring thrust bearing wear or shaft thermal expansion.

• Keyphasor®: Providing a once-per-turn pulse for speed measurements and phase timing.

• Eccentricity: Measuring shaft bow in large steam turbines during startup.
