Bently Nevada 330709-000-050-10-11-00 Proximity Probe: Technical Specifications, Product Description, Applications, Advantages, and Related Models

1. Product Overview

The Bently Nevada 330709-000-050-10-11-00 is a model identified within the 3300 XL 11 mm proximity probe family. Proximity probes of this type are designed for non-contact measurement of the distance between a sensor tip and a conductive target, commonly a rotating shaft in industrial machinery.

The probe is intended to operate as part of a compatible measurement system. When correctly installed and paired with suitable signal-conditioning electronics, it can provide measurements used to monitor shaft vibration, relative displacement, and other forms of mechanical movement.

The model number contains several configuration fields relating to the probe’s mechanical dimensions, cable arrangement, connector, and approval options. These details are important when selecting a spare part, replacing an existing probe, or checking compatibility with installed monitoring equipment.

Configuration note: the suffix 11 differs from the 02 connector configuration discussed in earlier models. Its precise meaning and compatibility should be confirmed against the product’s configuration documentation before purchase. It should not be assumed to have the same connector arrangement as a model ending in 02.

2. Brand and Product Series

The probe is a sensing component rather than a complete monitoring system. It needs the correct signal-conditioning hardware and monitoring equipment to convert its sensing response into usable measurements.

3. Correct Interpretation of the Model Number

For this model, the cable-length code is 10, which indicates 1.0 metre, not 5.0 metres. The connector and cable code 11 identifies a miniature ClickLoc coaxial connector with a connector protector and FluidLoc cable. The final 00 indicates that optional agency approvals are not requested.

4. Main Technical Characteristics

The following characteristics describe the 3300 XL 11 mm probe family and its typical installation requirements. Model-specific values should be checked against the applicable drawing before use in formal engineering documents.

The 50 mm case length is not the same as the complete installed length. The probe also has a cable and connector, and the final dimensions depend on the specific mechanical configuration. The product’s own mass should likewise be distinguished from shipping weight, which can include protective packaging and accessories.

5. Product Applications

5.1 Turbine Shaft Monitoring

The probe can be used in compatible turbine installations to measure relative shaft movement. In a properly designed measurement arrangement, this information can support vibration monitoring and help operators observe changes in the machine’s operating condition.

5.2 Compressor Monitoring

Industrial compressors often operate under demanding conditions and may require continuous monitoring. A compatible proximity-probe system can measure shaft movement at selected bearing locations and provide data for condition assessment.

5.3 Pump and Rotating Equipment Monitoring

The probe can be considered for suitable pumps and other rotating equipment where the shaft and bearing arrangement is designed for non-contact displacement sensing. The installation must provide an appropriate conductive target and the correct mounting geometry.

5.4 Axial-Position Measurement

In applications designed for axial monitoring, a proximity probe can detect relative shaft movement along the machine axis. The mounting position, target geometry, and measurement range must be selected for that specific function.

5.5 Machinery Protection Systems

When connected to compatible signal-conditioning and monitoring equipment, the probe can supply measurements used by machinery protection systems. The monitoring equipment, rather than the probe alone, determines how readings are displayed, recorded, and compared with configured alarm thresholds.

6. Product Advantages

The FluidLoc cable configuration is an important distinction from otherwise similar models with standard cable. Connector protection and cable construction should be considered when planning the installation, especially where cable routing and the surrounding environment may expose the connection to contamination.

7. Five Related Models

These models are useful for comparison within the same product family. Their configuration details differ, so they should not be treated as automatic replacements for the target model.

The fifth model above has a different base model, indicating an armored version in this product family. Its exact mechanical configuration must be checked before selection. If the application requires the same unarmored M16 × 1.5 probe, the base model should not be changed without confirming compatibility.

8. Five Other Common Models from the Same Brand

These models are used in related machinery monitoring systems, but they perform different roles. The dimensions and weights below are deliberately marked as unconfirmed where exact model-specific data is not available.

A proximity probe, extension cable, signal conditioner, and monitoring module are not interchangeable parts. When building or repairing a measurement loop, the complete combination must be checked against the intended application.

9. Dimensions and Weight for Procurement

For a formal quotation or equipment record, request the mechanical drawing and the actual product weight from the supplier. Do not use the cable length as the probe’s physical length, and do not substitute the shipping weight for the mass of the probe itself.

10. Installation and Maintenance

Before installing the probe, check that the mounting thread and 50 mm case-length option match the mounting point. Verify the cable route and make sure the connector protector can be fitted correctly.

The probe must be paired with the appropriate signal-conditioning equipment. The initial gap should be established according to the instructions for the complete measurement system rather than by using a generic setting.

During commissioning, confirm that the measurement is stable and consistent with the machine’s operating condition. Inspect the cable for crushing, sharp bends, abrasion, and excessive tension. Check that the connector is clean and properly secured.

If a measurement changes unexpectedly, examine the full measurement chain—including the probe, cable, connector, signal conditioner, mounting arrangement, and target surface—before replacing components.

11. Purchasing Checklist

• Verify the complete model number: 330709-000-050-10-11-00.
• Confirm the M16 × 1.5 mounting thread.
• Confirm the 50 mm case length and 0 mm unthreaded-length option.
• Confirm the 1.0 m cable length.
• Confirm the FluidLoc cable and ClickLoc connector with protector.
• Confirm that the 00 approval option is suitable for the installation.
• Check compatibility with the existing signal conditioner and monitoring system.
• Obtain the mechanical drawing if precise installation dimensions are needed.
• Confirm product weight and shipping weight separately.
• Inspect the supplied model label, connector, cable, and physical condition on receipt.

12. Conclusion

The Bently Nevada 330709-000-050-10-11-00 is a 3300 XL 11 mm proximity probe configuration with a 50 mm case-length option, a 1.0 m cable, a FluidLoc cable arrangement, and a miniature ClickLoc coaxial connector with protector.

Its principal function is to provide non-contact shaft-displacement measurements for compatible industrial machinery monitoring systems. Depending on the installation, these measurements can support shaft vibration, relative displacement, and axial-position monitoring.

The most important points when selecting this model are the complete part number, mounting dimensions, cable configuration, connector protection, approval requirements, and compatibility with the installed measurement loop. Exact product weight and full physical dimensions should be confirmed for the supplied configuration before they are entered into a formal technical datasheet.
